Retain AI + Klaviyo

Keep your flows on.
Add Retain AI alongside them.

Klaviyo powers the flows you’ve already built. Retain AI adds a new kind of message — truly personal, one-to-one. Together, they form a complete retention strategy.

AI customer segmentation

We use all context to find the customers who are most likely to convert.

Retain AI

Previous orders. Browsing history. Support conversations. And more. Our AI uses context from all your tools to find the lapsed customers most who are most likely to buy again.

Klaviyo

Even the most sophisticated segmentation your marketing automation platform can do requires pushing people through a common experience based on attributes or triggers.

True personalization

It’s not all about the email copy. It’s about each email being unique.

Retain AI

Per customer, AI decides which prior interactions to note, what products to recommend — and in what sizes, and what imagery to use. Each email is 1:1. Unique.

Klaviyo

Tools like Klaviyo were built for scale — and they’re great at blasting one message to millions. They simply weren’t designed for true 1:1, context-aware messaging.

High open rates

Remarkable AI emails land in the primary inbox for more visibility, opens, and conversions.

Retain AI

We use warm, two-way email addresses to land in the primary inbox, and follow-ups appear in the same threaded conversation. These emails feel too personal to ignore.

Klaviyo

Emails from your marketing automation platform are all but guaranteed to land in the promotions tab. Right next to the emails from allll those other brands.

Zero-effort optimization

Our AI learns with every send, so you get continuous improvement without ever needing an overhaul.

Retain AI

We let AI do what it does best: Learn and optimize. You get the benefits of continuous improvement and proven practices from across the industry. No effort required.

Klaviyo

Regularly optimizing your marketing automation emails and flows takes a ton of time, energy, resources, and fresh creative. (That’s why most brands don’t do it.)

Inbox position

Emails sent from existing help desk domains are likely to land in the primary inbox.

Marketing automation and sender domain land your emails in the promotions tab.

Threaded follow-ups

Follow-up emails appear as part of the same thread, for more natural conversations.

No ability to thread conversations. Each email is treated as a one-off.

Setup effort

No work required. Automated by AI and fully managed by Remarkable.

Very high effort. Average 12 – 14 FTE hours for a 3-email flow with only basic dynamic fields. Includes manual segmentation, flow building, email creation (copy and creative)

Optimization effort

No work required. Continuously optimized based on your campaign results and broader best practices.

High. Minimal adjustments may be quick, but are still manual. Larger refreshes to email strategy and creative require a heavy lift

Real talk

Retention is about revenue.

Most Klaviyo winback flows generate about 11 cents per recipient.

That’s not retention. That’s pocket change.

Retain AI delivers dollars — automatically.

1-click setup.

You keep what’s working.

FAQ

Still reading? Let us know if we’ve left anything unanswered.

How do you handle attribution? How can I tell if Retain is really driving the sale?

Your ecommerce platform shows which orders were influenced by Retain emails. We track time since the last order, which messages were received, UTM data, and whether customers bought the products Retain recommended. During your pilot, you also get reporting that compares Retain to control groups and your existing flows — so you can confidently prove the impact.

How do you count conversions?

Many platforms call a click a conversion. We don’t. Retain only counts a conversion when a customer actually places an order as a result of our outreach. Our focus is revenue, not clicks. That distinction matters when comparing Retain results to benchmarks or your own data.

I already send tons of emails. Why would I want more?

Retain isn’t about volume. It’s about precision. Our AI identifies high-potential customers and delivers one-to-one messages at the exact moment they’re most likely to buy. Brands using Retain see up to 50x more revenue per recipient — not by sending more emails, but by sending fewer, smarter ones.

How does this scale over time? Will you run out of customers to send to?

We recommend starting with 10% of your customer base, then ramping up to 60% over time. We can also test Retain on other flows, like 30-40 days post purchase and new subscribers who have never made a purchase.

What does 1:1 actually mean?

1:1 is short for "one-to-one." It’s true personalization, going way beyond “Hey {First Name}” or a mention of someone’s city. Retain AI crafts a unique message for each person, based on their behavior and history.

The example emails look like templates. Can’t I already do that in Klaviyo?

We get it. A sample email can look like a template — but it isn’t. With Retain, every message is different because every customer is different. AI pulls from each customer’s order history, browsing, and support interactions to decide what to mention, what to recommend, and how to personalize the links and images. The structure may look familiar, but the content is always unique. That’s what makes customers feel known in a way that flows can’t.

What if I use the same email copy and send it from Klaviyo?

Several customers tested that. They sent the same plain-text emails from Klaviyo as a control. The results? Klaviyo campaigns drove less than 10% of what Retain delivered. It’s not just about the email format or copy. The way Retain AI finds the highest-potential customers at the right time is an essential component of its success.
