Email List Segmentation Strategies That Increase AOV & Customer Lifetime Value

These audiences are smaller, but they convert higher. They’re ideal for limited-time campaigns, abandoned cart flows, and conversion pushes that feel timely, not spammy.

Purchase History

We’ve seen this pattern across multiple accounts: great open rates, but weak second purchases.

A first-time buyer might need education or a reason to return. A second-time buyer may be ready for bundles, loyalty perks, or a product swap. And a VIP? They’re looking for early access, exclusives, or surprise gifts.

This kind of segmentation doesn’t just boost AOV, it sets the stage for stronger lifecycle marketing. It also pairs perfectly with automated flows like replenishment, cross-sells, or limited-time offers.

Imagine getting an email from a brand you’ve bought from before. But the product isn’t relevant. The tone feels off. It reads like it wasn’t meant for you.

So you close it. Maybe you ignore the next one, too. Maybe you unsubscribe.

That’s what happens when every customer gets the same message, regardless of what they’ve clicked, viewed, or bought. That translates to a loss of interest and, with it, potential revenue.



And that’s why we need segmentation.  It lets you send messages that match where someone is in their journey. What they’ve shown interest in, what they’ve purchased, and what they’re ready for next.

This post breaks down the segmentation strategies we use to increase order size, bring customers back, and turn email into a higher-performing revenue channel.


Why Is Email Segmentation Important?

Because relevance drives results. And irrelevance kills them.

Segmentation lets you run multiple conversations at once, each tailored to what your customer actually cares about.
You get higher clicks, better deliverability, stronger AOV, and more chances to send—because your emails feel personal, not pushy.

The more relevant your message, the more likely they are to open, click, and buy again.

Tools like Klaviyo make this easier than ever. The question isn’t if you should segment.

It’s how far you want to take it.

The Best Segmentation Strategies to Increase AOV and CLV

Before we dig into advanced tactics, let’s zoom out.
At its simplest, most brands start segmenting with the
basics: active vs. inactive, new vs. returning, past purchasers vs. prospects.

But once you’ve got that foundation, the next step is building smarter, more intentional segments that tie directly to revenue.

The goal isn’t to push people to spend more. It’s to give them a path that fits how they already shop, and make the next purchase feel like a natural step.

These sends often outperform generic campaigns 2–3x because they speak to what the customer already wants.

This is one of the most effective ways to extend customer lifetime value—and make your best customers feel seen.

New vs. Returning Customers
Someone discovering your brand for the first time needs something different than someone on their third order.
New customers want clarity, education, and confidence in what they just bought. Returning customers are ready for upsells, product pairings, or review requests.

This segmentation forms the backbone of most smart post-purchase and winback flows, and it’s one of the easiest to build inside Klaviyo.

Start with a pop-up. Tag by profile. Build flows that speak to their actual goals.

When segmentation strategies like these are applied intentionally, the results aren’t subtle, they’re exponential.
