Fair warning. Ecommerce email marketing is not for the faint of heart.

And neither is this article.

It won’t unpack “email marketing definitions.” It won’t offer tips on “email marketing 101.” Why?

Because if you own or operate a growing business, that’s not what you need.

Instead, what you’re about to experience is an exhaustive and practical guide to acquiring new customers, retaining existing customers, and accelerating their lifetime value … all through the power of email.

Every step will be anchored in two things.

One, the full audit we use at Common Thread Collective to guide new clients. Two, a behind-the-scenes look at a multi-million-dollar brand with ambitious goals. 

And, for store owners looking to go above and beyond email — harness the power of SMS, WhatsApp, and Chat with the only multichannel, conversational marketing CRM for Shopify from our friends at Freshmarketer. 

Here’s the ecommerce email marketing path before us:
  1. Covering Your Email Service Provider Set-Up
  2. Capturing Subscribers to Build Your Email List
  3. Automating Welcome, Abandon & Post-Purchase
  4. Merchandising Your Email Marketing Campaigns
  5. Optimizing Creative: Subject Lines, CTAs & Content
  6. Diagnosing List Health, Segmentation & Personalization
  7. Testing Deliverability: Inbox vs. Spam + Unsubscribe Rates
  8. Reporting on the Right Email Metrics & Accurate Tracking
  9. BONUS: SMS Marketing That’s Essential and Intimate
  10. Prioritizing Your Ecommerce Email Marketing Strategy

But first, let’s pregame ⚾️ your ecommerce site, brand story & products

Every audit we conduct starts with the ecommerce business itself.

If you’re running your own brand, you likely have piles of documentation: style guide, voice and tone, aesthetics, product lists, a marketing calendar, assets library, and more.

Put all that away.

What’s crucial is experiencing your ecommerce store through the eyes of a first-time visitor.

In “Incognito” mode, visit your homepage on mobile then desktop.

Note the hero imagery, headline, featured products, and breadth of categories. Click through each main link in the navigation. As you do …

  • Read your About page out loud
  • Identify sold-out or discounted products
  • Locate any subscription or loyalty programs

To make this process as practical as possible, let me introduce you to Fielder’s Choice Goods. We’ll use it to evaluate every step and point from the audit:

Ecommerce brand Fielder's Choice (FC) Goods

Common Thread Collective acquired FC Goods for $5k. After growing it to ~$3M in annual revenue, we sold the brand and — during its transition to new ownership — provided full-service growth as well as email marketing.

Its hero products are handcrafted wallets made from upcycled baseball gloves. It also offers apparel and accessories.

FC Goods brand images

Fittingly, FC Goods majors on quality plus nostalgia. The About page reinforces those same elements. As do its product pages.

The tone is heartfelt and honest. The aesthetic, rich.

Videos showing off everything from its supply chain to manufacturing to origin story accentuate one theme: “We build our products because, like you, we love baseball. Together, let’s celebrate that love.”

FC Goods about page

Before jumping into the audit, take time to walk through your site the same way. Bonus points if you get a friend or new employee to do it with you. The value of fresh eyes cannot be overstated.

Now, onto the main event …

Checklist from a Klaviyo Email Marketing Agency: Covering Email Service Provider Set-Up

1. Has the ESP been integrated with the site backend?

First and foremost, have you connected your email platform directly with your ecommerce platform?

FC Goods relies on Klaviyo — hands-down our preferred email marketing software. If you go into the Integrations section, you can see that Shopify and Facebook are enabled.

Email service provider basics: Integration

2. Is a product catalog feeding into the ESP?

Data feeds fuel the merchandising side of flows (sometimes called, sequences or automations) with personalization and dynamic content.

Email service provider basics: Product Catalog

Data feeds can be customized in order to power dynamic recommendations with more control over what’s populated, but the default is all that’s required for most businesses.

Email service provider basics: Data Feed

3. Are tracking pixels installed to record behavior?

Tracking pixels come in two flavors.

One, onsite events to trigger flows around cart abandonment, browse abandonment, and purchases.

Email service provider basics: Tracking Pixel

Two, Facebook and other ad platforms to sync with Klaviyo lists and segments for Custom Audience Creation. This is imperative if you’re leveraging Facebook Lead Ads.

Capturing Email Subscribers to Build Your List

4. Is there an effective pop-up for lead capture?

Observe onsite email capture tactics through the lens of a consumer. Again, visit your online store in an “Incognito” window to note:

  • How quickly does the pop-up appear?
  • Where and when does it display?
  • Is there an incentive for sign-up?
  • Is the creative compelling?
  • Is it inclusive of SMS and email?

FC Goods has a universal pop-up that fires shortly after landing on the site. Submitting an email address immediately leads to SMS opt-in, so they’re fueling both their email and text programs.

The incentive is a giveaway for a free wallet. Typically we don’t recommend giveaways as they can produce low-quality, freebie-seeking leads.

effective pop-up incentives for building your email list

Without an incentive to grease the wheels, there’s little reason for me to check my inbox. I’m probably not going to hear right away if I’ve won.

Nonetheless, it’s compelling. Powered by JustUno, the creative is strong and the pop-up converts at 3.48%; with a seasonal spike of 8.36%.

pop-up conversion rate statistics from JustUno

Eight percent crushes as a pop-up. Still, if we find lead quality isn’t equally crushing — based on welcome conversions — I’d recommend testing a few different sign-up offers:

  1. Percentage off
  2. Free shipping
  3. Buy X, Get Y

Ecommerce website pop-up marketing examples: Using a percentage off (APL), free shipping (Love Wellness), or buy'x' get 'y' (Thirty One Bits) incentives to build your email list

Use both sign-up rates and revenue to determine which works best.

5. Are forms present in the header or footer?

Next, we want to see a form for email capture in either the header or footer. On FC Goods, there’s a “Subscribe” box in the footer that leans on scarcity to entice.

Add forms to your ecommerce websites header or footer to build your email list

With every sign-up source, go through the process of subscribing to test if contacts …

  • Flow into the ESP
  • Receive the welcome series
  • Get added to relevant lists or segments
6. Is sign-up prompted at checkout? If so, is marketing pre-checked?

Like all ecommerce sites, FC Goods’ checkout collects emails. It also contains a checkbox to sign up for text messages, enabling a strong cross-channel experience between email and SMS.

The more options you give your customers to connect with your brand through the channels they prefer, the better.

FC Goods ecommerce checkout fails to request email-marketing consent

Unfortunately the cart doesn’t ask for email marketing consent, instead focusing on TCPA compliance for their SMS opt ins. Both should be present in this case.

Without that, you could easily fail to comply with GDPR and CCPA for Canadian or EU shoppers. Brands that only ship to the US are free from this constraint.

Automating Welcome, Abandon & Post-Purchase

Welcome Email Series

A welcome series is likely to be one of your top revenue-driving flows.

An effective series should onboard new subscribers, educate them about your brand, and propel them toward first purchase.

7. Is there a compelling welcome series active to motivate first purchase?
  • How quickly does the first message deploy?
  • How many emails are in the flow?
  • Is there an offer present? If so, what is it?
  • Does the series highlight the brand’s UVP & breadth of products?
  • Can subscribers receive marketing messages while in this flow?

Here’s an overview of FC Goods, which we’ll examine bullet-by-bullet:

How quickly does the first message deploy?

Immediately; there’s no delay before the first message.

Triggering an email as soon as someone signs up alleviates anxiety and accelerates conversions.

How many emails are in the flow?

Six; we recommend starting with the three to five and monitoring engagement throughout to determine if emails should be pivoted, added, or removed.

This one kicks off with a 45% open rate and 7% click-through rate. By the last message, we’re at a 20% open and 2% click. These engagement rates are what we’d expect from batched campaigns, rather than a highly personalized flow.

This tells me the messages further down need subject line testing, creative refresh, or should simply be cut in order to move the subscriber into more timely campaigns.

Is there an offer present? If so, what is it?

No; sadly, it opens with “Thanks For Stopping By.” There’s a nice note from the founder. But the first touch doesn’t mention the wallet giveaway or provide a reason to convert right now.

ecommerce thank you email example from FC Goods

Does the series highlight the brand’s UVP & breadth of products?

The rest of the flow showcases its story, background, and what makes the product special.

welcome flow email marketing examples from ecommerce brand FC Goods

The biggest opportunity lies in merchandising.

The “Shop Now” CTAs all lead to collection pages. That means, the customer arrives several clicks from carting an item. And even more clicks away. from completing a purchase.

Instead of being general …

Make your CTAs drive to landing pages with specific hero products. This shortens the path to purchase.

Can subscribers receive marketing messages while in this flow?

Flow filters govern what actions qualify or disqualify a subscriber. The most-crucial filter for a welcome series is “Placed Order.” The moment a potential customer becomes an actual customer, remove them from your welcome flow.

ecommerce email flow triggers and exclusions

Consider how and when to exclude subscribers from ad-hoc campaigns — like seasonal events, sales, and new product releases.

Smart Sending limits the number of emails a recipient gets within any given time period. Excluding major moments, personalized messages anchored in past behavior convert far better than one-size-fits-all.

Abandoned Cart Emails & Browse Abandon Emails

8. Are cart and browse recovery retargeting potential customers?
  • How quickly does the first message deploy?
  • How many emails are in the flow(s)?
  • Do the emails contain dynamic content of the item(s)?
  • Is there an offer present? If so, what is it?

Abandonment emails exist for a single reason: getting people back to their cart to convert.

Here’s an overview of FC Goods’ abandoned checkout:

How quickly does the first message deploy?

One hour; fantastic!

Klaviyo’s template defaults to four hours. Based on our experience across dozens of clients, that’s too long.

One to two hours is an optimal starting point to get shoppers back to your online store while the product is still top of mind. And before they can purchase something similar from your competitors.

How many emails are in the flow(s)?

Five; that’s quite a few messages for a cart flow — you might be in the territory of irritating someone if they’ve decided the product isn’t right for them.

Normally, three emails are enough to address the reasons they should convert: product quality, scarcity, easy returns, etc.

For FC Goods, the open and CTRs remain high throughout. Why?

Likely because its products are heavily weighted towards gifting. Buying for someone else — particularly something with a relatively high price point — involves more shopping around and a longer consideration phase.

Evaluating the window for email remarketing requires a slightly different approach from paid social remarketing.

On social media, you’d adjust your window based on the Time Lag from Google Analytics to avoid overspending on contacts who are unlikely to convert.

On social media, you would adjust your email marketing window based on the Time Lag from Google Analytics for your ecommerce business

Email is significantly cheaper for retargeting, so you can rely instead on engagement metrics within the flow itself to determine how often and for how long to attempt to recapture those carts.

Do the emails contain dynamic content of the item(s)?

Yes; plus, they’re one-for-one.

Dynamic content should showcase exactly what someone left in their cart. This instantly provides a visual recall: “Hey, you were interested in this! Come back and complete your order.”

dynamic content built into your email marketing templates for ecommerce

Is there an offer present? If so, what is it?

Yes; every email in the sequence drives shoppers back to their cart through dynamic content.

Even better, discounts aren’t offered until the last two emails:

ecommerce marketing emails offering discounts are pushed to the bottom of your email flow

Usually, people just need a gentle nudge to come back and convert.

Providing a discount too early could mean unnecessarily cutting into your margin. Open with a reminder and delay discounting. You don’t want to sacrifice profit if you don’t have to.

Post-Purchase Email Series

Post-purchase emails drive recurring orders, improve retention, and increase customer lifetime value (CLV).

A post-purchase series should (1) thank customers, (2) help them get the most out of the product, and (3) entice a second purchase through cross-selling or a bounceback offer.

9. Is there a post-purchase series to accelerate LTV?
  • How quickly does the first message deploy?
  • How many emails (or SMS messages) are in the flow?
  • Are purchased product(s) displayed dynamically?
  • Is excitement built for the impending delivery?
  • Does it explain how to use products for maximum enjoyment?
  • Does it solicit feedback: NPS, review request, or otherwise?
  • Is it segmented for first-time vs. repeat customers?
  • Is there an offer present? If so, what is it?
  • Are customers asked to leave a review, refer a friend, or take other action as brand ambassadors?

How quickly does the first message deploy?

With branching logic early in the flow: messages for repeat purchasers fire immediately; first-timers get a one-hour delay.

FC Goods also triggers order confirmation emails through Shopify. Staggering transactional messages coming from the site versus your ESP avoids overcommunication.

branching logic for 'Placed Order' email flow

How many emails (or SMS messages) are in the flow?

Based on customer type, the flow ranges from one email for returning customers … to eight for first-timers who indicated the purchase was for themselves.

Respect your repeat purchasers by avoiding too much communication. But don’t miss out on feedback or referrals from customers who have indicated enthusiasm for your brand.

Are purchased product(s) displayed dynamically?

No; using a post-purchase flow to remind users what they ordered and provide care instructions can go a long way in providing a fantastic customer experience.

Is excitement built for the impending delivery?

Not really; the first email contains a personal note from the founder reinforcing the brand’s origin story. Making your customers feel like they’re part of something meaningful can drive affinity and loyalty.

From there, however, the flow pivots to different products rather than the story behind or tips on how to use the product ordered.

Does it explain how to use products for maximum enjoyment?

No; the series doesn’t branch based on product purchased, so it’s difficult to serve personalized emails that speak to care.

This type of messaging goes a long way in building relationships. It shows a genuine interest in helping them get the most out of the product and ensuring longevity.

Does it solicit feedback: NPS, review request, or otherwise?

No; while FC Goods has customer reviews onsite, they’re not actively soliciting them via email. A simple message requesting feedback can help to drive a higher volume of reviews.

Is it segmented for first-time vs. repeat customers?

Yes! Messaging for new customers vs. repeat purchasers should be different.

First-timers need education in the form of how-to content. Returning customers should be rewarded — or, at the very least, praised — for their loyalty.

Is there an offer present? If so, what is it?

Free monogramming is offered to first-time purchasers, whether they indicated their initial purchase was for themselves or for a gift. This offer may not be compelling for a broad swath of users, especially since monogrammed items cannot be returned.

Testing a straightforward offer like percentage-off, dollar-off, or a gift with purchase can confirm the right approach.

Are customers asked to leave a review, refer a friend, or take other action as brand ambassadors?

No; repeat customers, in particular, are only receiving one message.

Capitalize on loyalty by requesting reviews explicitly or through referrals to drive new-customer acquisition.

Warning about ‘skipped subscribers’

Notice Email #13 under the branch for customers who bought “as a gift.” 314 people have been “Skipped” in the last 90 days.

email marketing analytics view from ecommerce brand FC Goods Klaviyo account

Clicking “View all Analytics” and then “Recipient Activity,” you can see why: 44 were because FC Goods was over its email limit and 223 were because of a coupon issue.

skipped email list

The brand is using dynamic coupon generation and probably ran out of codes. Or, there might be an error in the account. Because the coupon couldn’t be created, the user was just skipped.

BONUS: Nine More Automated Emails for the Entire Customer Journey

Welcome, abandonment flows, and post-purchase sequences set the foundation.

But, you should implement a number of additional flows to take full advantage of a subscriber’s behavior and location in the funnel.

flow overview from FC Goods email marketing for ecommerce

Non-purchaser flow: For subscribers who signed up, progressed through the welcome series, but didn’t convert. Remind them of sign-up incentives or add a deal-sweetener to get them to purchase.

Cross-sell or upsell flow: For all customers based on related products, commonly purchased-together products, or similar products. Is the timing effectively driving up short-term LTV and payback windows?

Re-engagement (reactivation): For subscribers who haven’t opened or clicked recently. Too many businesses focus on the net-new side of email. Instead, balancing list growth with list hygiene keeps your revenue strong without putting the program at risk of deliverability issues.

Review requests: May be part of a comprehensive post-purchase series or a stand alone. Regardless, base your timing on how long it takes for a customer to receive their product and use it long enough to leave an informed review.

Loyalty or referral: Likely triggered from a platform other than your ESP, but worth implementing thoughtfully. Relying on loyalty templates makes it difficult for your program to stand out or compel engagement.

VIP flows: Possible without the investment in a loyalty platform. Consider what makes a customer a VIP — total spend, number of orders, etc. Then, set up custom triggers for when users are close to achieving VIP status. Or, to celebrate their achievement.

Winbacks: For customers who made a purchase but haven’t come back within a certain timeframe, maybe 60 to 90 days, depending on the typical repurchase rate.

Milestones: For birthdays, purchase anniversaries, and VIP programs. We normally tier the rewards for milestones by the number of purchases rather than treating everyone the same.

Merchandising Your Email Marketing Campaigns & Newsletters

Individual campaigns communicate timely messages to a broad audience of subscribers. This can include major sales, product launches, or seasonal stories.

A regular campaign cadence keeps your brand top of mind, drives cookied-email users to the site for behavioral tracking (to power your abandonment flows), and keeps your sender reputation strong.

When you navigate to the Campaigns page, you can see a laundry list of emails that have been sent.

ecommerce email marketign campaign list

This view provides a snapshot, including cadence, segments in use, high-level KPIs, and how email and text messages are used in tandem via Klaviyo’s native SMS functionality.

10. How often are broadcast campaigns deploying?

Is the frequency of messages right for the brand and product line? Is it consistent?

Yes and no.

As a gifting brand, FC Goods sent 30 campaigns between the middle of Nov. and the end of Dec. Ten of those were Black Friday, Cyber Monday related:

ecommerce gifting brand FC Goods email marketing examples sent between November and December 2020

On the “no” side, nothing happened between Dec. 23rd and Feb. 10th. Automations continued, but if someone didn’t visit the site or engage in qualifying behaviors …

They wouldn’t have received any email for over a month.

On top of missed revenue and neglected relationships, the biggest issue with this is deliverability.

Internet service providers look not only at your reputation and authentication when evaluating whether or not your email should go to the inbox or the spam folder, they also look at peaks and valleys in your send volume.

A regular cadence of just two or three emails per week — unless you have good reasons to mail more — gives subscribers consistency and ensures your messages end up being seen.

11. Does the marketing calendar offer a good mix of messages?

Is there a healthy ratio between promotional emails, launches, and content-driven, story-heavy messages?

Again: yes and no.

Naturally, FC Goods’ calendar leans heavily towards the holidays. Its Christmas emails — including Black Friday, Cyber Monday — speak directly to urgency.

Still, there’s more that it (and, probably, you) can do to make the benefits of the product come alive.

The product pages do a fantastic job of diagramming the benefits of its flagship wallets. Similarly, a wealth of content centered on its Limited Edition collections exists behind the scenes.

All that remains untapped in its ongoing campaigns:

FC Goods PDP (product description page.) 'How we make this wallet...'

Full-color booklet for the 70's series

Signature series booklet that tells the full story of the 1919 'Black Sox' scandal

The solution? Sell stories, not products.

A whopping 86% of consumers say authenticity is a major factor when considering which brands to give their business to.

Spending all of your time pushing products or discounts while failing to convey your how and why … will leave your customers feeling zero connection — a kiss of death for building a healthy foundation of repeat purchasers.

FC Goods was born out of a love of baseball — a uniquely American cultural touchstone. This gives it baked-in emotional connections through appreciation for the sport and the memories made with friends and loved ones watching the game.

The products themselves pack a nostalgic punch. Coupling sourcing and production with stories from baseball’s past should evoke an emotional connection. But only if you show and tell your audience.

If, like FC Goods, you’ve already done the legwork to create content …

It simply needs to be sown into campaigns that celebrate the sport — especially during timely moments or within onboarding and post-purchase flows to drive relationship-building narratives.

12. Are emails effectively merchandised?

Are the emails shoppable? Do the links make it easy to get back to the relevant pages on the site? Are CTA buttons present throughout?

Yes, yes, and yes. Though — not surprisingly — there’s room for improvement.

Let’s use three examples as test cases …

(1) Grab a Gift Card

FC Goods Gift Card Email

Obviously, this campaign promotes digital gift cards for last-minute gifters around the holidays. Tweaking a few things could increase clicks and purchase intent:

  • Pare down the copy to make it skimmable; get people back to the site and shopping quickly
  • Move “With only 2 days left until Christmas” into a top banner for additional urgency

(2) Free Upgraded Shipping

upgraded shipping emails

Sent in mid-Dec., both messages include timely offers with strong urgency. What else could they do?

  • Add banners underneath the “Shop Now” button with wallets, accessories, belts, and other popular products to cut down the number of clicks to convert
  • Link those banners — and preview images — directly to product pages rather than collections
  • Alternatively, categorize the CTAs by the type of person who’d be interested in each wallet; rather than lead with the product, use personas to connect the dots for gift-givers

(3) Back In Stock & Low Stock

back in stock and low stock warning emails from FC Goods retention marketing strategy drive ecommerce sales

If you have products that go in and out of stock (OOS) frequently, it’s a lot of manual work to create individual campaigns. Automating back-in-stock messaging can significantly reduce the level of effort to execute.

Before the product goes OOS, target people who have browsed within the last 30 to 60 days with low-inventory triggers. Sell-out risk and scarcity can drive shoppers to quickly convert:

  • “We saw you checking out [product]. Inventory is running low — come back and claim yours before it’s too late.”
  • “Good news, [name], [product] is back. But probably not for long.”
13. Are the emails error-free?

Yes; admittedly, proofing your emails is the least exciting part of the entire process. Once they go out, you can’t take them back.

A quality assurance (QA) checklist will save you loads of heartache and embarrassment. Send a test on desktop and mobile to review …

  • Copy for spelling and grammar
  • Links for correct landing pages
  • UTM parameters for tracking
  • Image “alt text” for accuracy
  • Coupon codes for functionality
  • Featured products for availability
  • Fine print for disclaimers and expirations

Optimizing Creative: Subject Lines, CTAs & Content

14. Do the subject lines and preheaders entice opens?
  • Does the subject make the reader want to learn more?
  • Does it use personalization where relevant?
  • Does the subject interplay with the preheader?
  • Does the inbox preview match the message within?

Sure, it’s email marketing 101 (and I told you we wouldn’t cover that kind of thing). Here, I’ll make an exception. For good reason: subject lines have a huge impact on performance.

Review your subject lines subjectively — using the list above — and objectively, through open rates.

15. Do the content, copy, and calls-to-action drive clicks?
  • Is the creative engaging and on-brand?
  • Is there an effective messaging hierarchy?
  • Are CTAs present throughout?
  • Do layouts vary from send to send?

To answer those questions, we’ll examine three recent campaigns of varying lengths and for different products: (1) hats, (2) Valentine’s Day gift cards, and (3) a holiday “one last email” message.

different length email examples from FC Goods

Is the creative engaging and on-brand?

Yes; the photography grabs my attention. The copy is approachable and easy to skim, making me want to explore. Most importantly, when I click through, there’s cohesion between the inbox and the landing page, assuring me I’m in the right place.

Is there an effective messaging hierarchy?

Yes; they’ve got a good headline that frames the story, sub-copy that provides more detail and builds up purchase intent, and then a CTA that tells the reader exactly what to do.

Are CTAs present throughout?

FC Goods includes a CTA button in every email, sometimes multiple to differentiate sections of content or corresponding landing pages. While there are some instances where I’d like to see a CTA fall higher in the email, overall they’re mostly hitting the mark.

Do layouts vary from send to send?

Somewhat. While the photography changes from message to message the layout does not. Most follow the formula …

  • Hero image
  • Headline
  • Body copy
  • Button

Infuse different layouts and templates to maintain visual interest and keep people opening and scrolling.

16. Is dynamic content being used to power personalization?

No; for FC Goods — and for you — dynamic content should be a top priority to easily layer personalization into campaigns and flows without manual effort.

Klaviyo makes it easy to personalize data feeds and drop in product blocks with dynamic recommendations based on popularity or what a user has shown interest in.

Klaviyo personal data feed setup

Beyond recommendations, banners can dynamically hide or display content based on a contact’s profile details.

For instance, if you’re running a promotional campaign specific to a geographic area, you can create one email and use dynamic blocks to hide or display promo details based on location:

17. Do the emails render on desktop, mobile, and dark mode?

Yes; CTC utilizes Email on Acid to preview across hundreds of devices and inbox to ensure a positive experience no matter the device or ISP.

review email renders on different ESPs

If you don’t have access to a preview tool, you can fake it by checking a few key things across your personal devices.

Send a live test of a message to yourself and open it on a laptop, tablet, and phone. Make sure the images scale as expected and the message is readable, even in dark mode.

A note about accessibility

Many ecommerce retailers rely on sliced images in their coded emails. This can help to maintain the integrity of the aesthetics and custom fonts.

The downside? It’s not optimal for accessibility — it can make it difficult for people with disabilities to navigate your content.

CTC utilizes a blended approach to coding, adding live text over background images for important content, or where a webfont in line with our clients’ branding.

Some marketers, however, may not have the technical ability to execute in this way.

At a minimum, add ample alt text on your images. The text should reflect the entire content of the message, render legibly, and be easy for a screenreader to process. View your emails with images turned off to see how your alt text comes across.

Email Accessibility and Ecommerce Marketing

18. Is there a lag in load time?

Nope; FC Goods’ emails load quickly no matter the device, indicating appropriately sized images. Subscribers have a short attention span and will sooner trash your email than wait around for it to load.

Diagnosing List Health, Segmentation & Personalization

Scaling your email list is crucial to driving healthy revenue from your program, but don’t get caught up in the vanity of a high subscriber count.

Quality > Quantity.

Not only are you spending more money on your platform fees to mail to unengaged contacts, but you could put your entire program at risk without proper list hygiene.

Chronically low engagement tells ISPs that you’re not following healthy sender practices.

19. What is the current active contact count?

At the time of this audit, FC Goods regularly mailed to an audience of ~59K contacts who had opened in the last six months.

Engagement reports reveal where you should tighten the window. Unengaged contacts negatively impact performance and deliverability.

Email marketing for ecommerce engagement dashboards indicate overall list health

Using that segment as a baseline, establish four additional segments:

  1. Prospects
  2. One-timers
  3. Two-time purchasers
  4. Loyal customers (three or more purchases)

Customer Status: Active Subscribers based on '6 Months Engaged' sending segment from FC Goods email marketing list

In this case, a more effective onboarding process is necessary to convert prospects into customers. We fast-track repeat purchasing through a post-purchase flow, winback campaigns, and other loyalty efforts.

20. Is new contact acquisition outpacing churn?

Yes; delivered counts show the audience is growing over time.

For better insight into how growth is pacing against churn, compare list size against new contacts added month-over-month. Pay attention to two common culprits: high unsubscribes and users lapsing due to lack of engagement.

email marketing list and segment statistics relevant for ecommerce brands

21. Are engagement parameters present?

Yep; recently sent campaigns display the segments in active use for FC Goods. Most rely on recency of engagement to qualify.

Klaviyo Campaigns Dashboard

Avoid static lists where people can age out or stop opening without being removed.

22. How effectively is segmentation being leveraged?

Are engagement, purchase behavior, demographics, first-party data, etc. factored in?

For the most part, FC Goods sends batched campaigns to a broad audience with little segmentation.

That’s not necessarily bad. It’s just an indication that personalized experiences aren’t being leveraged as much as they could be — whether that means tailoring based on customer status, demographic data, or purchase behavior.

Don’t let segmentation overwhelm you …

Instead, create test segments based on your primary mailing audience to determine:

  • What percent of the active list has purchased?
  • How often do they repurchase versus buy once?
  • What category of products are repurchased?
  • How many subscribers are in your loyalty program?
  • How many have failed to open recently? Click recently?

Based on your answers, layer in segmented personalization through dynamic content by serving product recommendations or displaying loyalty points or tiers.

Take it a step further by tailoring messages for specific audiences, or adjusting your mailing practices to match the frequency of messages with a subscribers’ engagement level.

Testing Deliverability: Inbox vs. Spam + Unsubscribe Rates

Maintaining a healthy unsubscribe rate is just one piece of the deliverability puzzle.

Some contacts won’t put in the effort to unsubscribe but will instead sit on your list without engaging, putting you at risk of deliverability issues across the program — even with your engaged users.

23. Are emails landing in the inbox or spam folder?

Inbox; well, for me anyway. The only way to be sure they’re doing so across ISPs is to use a deliverability monitoring tool with active seed lists.

These can be prohibitively expensive for small brands, but using Klaviyo’s Open Rate report grouped by Email Domain can give you an at a glance view of recent opens to help you catch problems early on.

Rates are fairly consistent across ISPs, with similar peaks and valleys, so we can assume all is well.

24. Are unsubscribes and spam complaints healthy?

Happily, they are!

Unsubscribe rates by email type are on a steady decline, indicating subscribers are happy with the frequency and content of messages. Aim for half a percent or below for your account.

With flows accounting for a higher share, it’s worth digging into which are driving the opt-outs to find issues that might be annoying subscribers.

Spam complaints, on the other hand, trend upward. Anything over .1% is cause for concern and should be further investigated.

25. Are emails sending from a dedicated subdomain?

No; FC Goods’ email campaigns come directly from their root domain:

Any issues with their marketing emails (spam complaints, blacklists, etc.) could affect their ability to send and receive emails internally or for transactional-email purposes.

26. Are accurate UTM parameters in all links?

Yes; FC Goods appends with Klaviyo’s automatic UTM parameters.

We highly recommend brands take advantage of this functionality (customized to meet your needs) to track in Google Analytics. This enables a better understanding of email’s role in traffic, revenue, and conversions using a consistent last-click attribution models.

27. Are conversion rate and revenue being tracked in the ESP?

Indeed, they are; if your Shopify integration is set up properly, conversion and revenue tracking will happen automatically.

That said, monitor the difference in attribution between Klaviyo — which uses a view-through model — and Google Analytics, which uses last click.

Klaviyo’s reporting will always take credit for more conversions than Google Analytics. Klaviyo attributes conversions to email for any users who opened or clicked a message within a specific time frame before converting, regardless of the source of the session when the conversion occurred.

28. Are key KPIs (open, clicks, conversions) in a healthy range?

Klaviyo recently added Benchmarks to their Analytics suite, making it easy for brands to compare their performance to peers in the same industry.

29. What percent of site revenue is email driving?

BONUS: SMS Marketing That’s Essential and Intimate

30. Is SMS used? If so are …
  • Welcome texts in place and optimized?
  • Abandonment texts in place and optimized?
  • Broadcast texts effective, valuable, and respectful?

SMS is an incredibly powerful platform for driving revenue for a retail brand, and it is made even more powerful when it is cohesively integrated with email marketing.

An SMS audit follows a similar structure to email: making sure strong capture tactics are in place on the site, ensuring key flows are live and optimized, and that broadcast campaigns are being used effectively and respectfully.

There’s a lower tolerance for frequent communication via SMS as it’s a more intimate communication channel.

Send one to two broadcast campaigns a month, segmenting as much as possible and pinging your customers only when it’s worth it. SMS notifications can quickly begin to feel intrusive when overused or used inappropriately.

If your customers are anything like me, they sleep with their phones next to them. Following a quiet hours is crucial. Do not deploy SMS messages between 9:00 PM and 9:00 AM at the recipient’s local time zone.

Aside from time and cadence, email and SMS ought to coordinate seamlessly in a way that plays to the strengths of each channel.

SMS shines through short, timely, quick calls to action and urgent messages. For example, in a cart-abandonment flow to notify a subscriber their cart is about to expire or granting early access for a major sale.

Email marketing, by contrast, is much more effective for visual and longer-form storytelling.

In any event, make sure you’re not sending the exact same message via SMS and via email at the same time. It is highly likely you’ll have subscribers who are engaging with your brand on both channels. Don’t duplicate efforts or blast people with the same message at the same time.
