April Retention Newsie

Welcome to The Retention Newsie by The Email Marketers - your biweekly dose of what's actually working in email and SMS retention for e-commerce brands. No fluff, no recycled 'best practices.' Just what we're seeing in the trenches with 50+ brands.

Let's get into it.

πŸ“Š Anonymous visitor ID: The tool war heating up behind the scenes

Here's a question one of our clients asked us last month that stopped us in our tracks:

Are we segmenting ourselves into niches that end up missing people?

Short answer: probably.

We've been preaching segmentation for years β€” and we still believe in it. But there's a version of 'good segmentation' that quietly turns into a revenue leak, and we're seeing it more and more.

Here's what over-segmentation looks like in practice:
β€’ You have 14 different welcome flow variations, and half of them haven't been updated in 6 months. On top of that, a few of them only have a handful of people go through them every month.
β€’ Your 'VIP' segment has 200 people in it because the criteria is so tight that almost nobody qualifies.
β€’ You're sending to smaller and smaller slices of your list, and your total email revenue is declining even though open rates look great.
β€’ Your team spends more time managing segments than actually sending emails.

Sound familiar?

The mechanism is sneaky. You start with a smart hypothesis β€” 'first-time buyers need different messaging than repeat customers.' Correct. But then you split first-time buyers by product category, then by acquisition source, then by geography, and suddenly you've got 47 segments and each one is getting maybe one email a month.

The reality: A segment that's too small doesn't have enough volume to generate meaningful revenue OR meaningful data to optimize from. You're flying blind with a blindfold you put on yourself.

What we recommend instead:

1. Audit your segment sizes. If a segment has fewer than 500 active profiles, question whether it needs to exist as its own flow path. Whether it exists as its own flow path, the 80-20 rule is helpful. Can you generate 80% of the results with 20% of the work? Or are you putting in 80% effort to generate 20% results?
2. Start with two welcome paths, not twelve. Klaviyo's own audit team reviewed nearly 100 accounts last year and the #1 recommendation was simple: split your welcome flow by purchase status. New subscriber vs. new customer. Two paths. Not twenty.
3. Measure total revenue, not just per-send metrics. A 60% open rate on a segment of 150 people looks amazing in your dashboard and is great for deliverability but will generates less revenue than a 35-45% open rate on a segment of 5,000. There’s a fine line between optimizing for revenue and for deliverability and you need to do both.
4. Consolidate quarterly. Every 90 days, look at which segments are actually driving revenue and which ones are just making your flow builder look complicated.

The brands winning at retention right now aren't the ones with the most segments. They're the ones with the right segments and the discipline to keep things clean.

Our team flagged an industry-wide trend to our clients last month: DTC brands are getting hit with privacy-related claims at an accelerating rate.

This isn't theoretical. We sent a proactive alert to our client roster because the pattern was clear enough to warrant it.

What's happening:
Privacy litigation targeting e-commerce brands has spiked in 2026. The claims range from improper cookie consent to SMS compliance gaps to third-party data sharing violations. And the plaintiffs' attorneys have gotten very efficient at filing them.

What makes this different:
β€’ These claims aren't just targeting the big brands anymore. Mid-market DTC brands are now in the crosshairs.
β€’ Many claims center on anonymous visitor identification tools, the same tools many brands recently adopted to grow their lists faster.
β€’ TCPA enforcement around SMS continues to tighten, with penalties up to $1,500 per violation.

What we're telling our clients:
1. Audit your data collection stack. Know exactly what's being collected, by whom, and whether your consent mechanisms are bulletproof.
2. Review your SMS opt-in flow. 'Implied consent' is not consent.
3. Check your anonymous visitor ID tool's compliance. Not all providers handle consent the same way.
4. Document everything. If a claim comes, your defense is your paper trail.

Spending a few hours on compliance now saves you six figures later. Don't sleep on it.

πŸ”§ Klaviyo's 75+ Product Updates: What Actually Matters

Klaviyo just dropped a massive update roundup. Here's what we care about:
β€’ Customer Agent improvements: Klaviyo's AI assistant is getting smarter at suggesting segments and flow triggers. Still not a replacement for a strategist, but useful for quick analysis.
β€’ Composer changes: The email builder got a refresh. Faster loading, better mobile preview. Small things that add up when your team lives in the builder.
β€’ Extended ID: If you haven't turned this on yet, do it today. It lets Klaviyo identify more site visitors, which means larger flow volumes and better segmentation data. This showed up in nearly two-thirds of Klaviyo's own account audits as a missed opportunity.
β€’ The rest? Mostly incremental. Nice to have, not need to have.

πŸ€– ShopTalk 2026: AI Was Everywhere

ShopTalk March 2026 | Las Vegas


We got back from ShopTalk a few weeks ago, and the consensus was clear: AI and automation dominated the conversation among agencies, brands, and tech partners.

Our take: Most of what's being labeled 'AI' in retention marketing right now is really just better automation with a fancier name. The actual game-changers like predictive send-time optimization, AI-generated subject lines that consistently outperform human ones, automated flow creation are still early. Worth watching, but not worth betting your Q2 on.

πŸ”οΈ Anonymous Visitor ID: The Tool War Heats Up

We're actively helping clients evaluate Retention.com vs. Customers.ai for anonymous site traffic identification. Both promise to identify visitors who don't fill out forms and feed them into your flows.

The reality: both work, but the compliance picture is evolving fast (see our privacy section above). We're recommending brands evaluate not just match rates but legal risk before committing. This space is going to look very different by Q4.

πŸ“‰ Is Email-Only Growth Hitting a Ceiling?

Klaviyo published a piece arguing that siloed email programs limit growth and brands should consolidate channels. We agree, to a point.

Our take: Email is not hitting a ceiling. Lazy email is hitting a ceiling. Brands that treat email as a batch-and-blast channel will plateau. Brands that build intentional lifecycle programs with email + SMS + on-site capture will keep compounding. The channel isn't the problem. The strategy is. And we have seen that email-only brands struggled with BFCM 2025 significantly more than those that used email and SMS.

πŸ“Š Yeah or Nay?

How many segments do you actively use in your email program?
A) 1-5 (keeping it simple)
B) 6-15 (structured but manageable)
C) 16-30 (getting complex)
D) 30+ (send help)

Reply and let us know β€” we're genuinely curious where most brands land on this.

β€œHands down the best & easiest-to-work-with email/SMS marketing agency! We had an extraordinarily tight timeline going into our first project, and Melanie and her entire team took care of us, going above and beyond to make sure we'd be successful. They quickly adopted our brand voice and created beautiful flows that we barely needed to edit. There's a saying that I love – "hire someone you'd happily work for," and that perfectly describes our experience with TEM.”
