The Two Segments That Actually Drive Revenue
Most ecommerce brands send every campaign to a single generic engaged list. They treat someone who has purchased five times exactly the same as someone who opted in yesterday and never spent a cent. That is a mistake.
If you want to turn the highest possible number of subscribers into first-time buyers, you need to split your engaged audience into two distinct groups: those who have placed an order before, and those who have not. We implement this setup for every single client at In-box.
Your campaign strategy then becomes remarkably simple. You create one core campaign, clone it, and send it to both groups with one crucial difference: non-purchasers get a reminder to use their welcome discount, while existing purchasers get the clean campaign with zero promotional discount.
How to Build Your Engaged Segments Properly
Deliverability is the foundation of every high-performing Klaviyo account. Before splitting by purchase history, you need a rock-solid definition of recent engagement so your emails actually land in the primary inbox.
Here is the exact criteria we use for an engaged non-purchaser segment over a 60-day window:
- Engagement: Has opened email at least once in the last 60 days OR clicked email at least once in the last 60 days OR active on site at least once in the last 60 days OR subscribed to list at least once in the last 30 days.
- Deliverability protection: Bounced email zero times in the last 30 days.
- Consent: Can receive email marketing (subscribed).
- Purchase history: Placed order zero times overall.
We include the 30-day recent subscription rule because fresh sign-ups might not have had an opportunity to click a regular campaign yet. For your engaged purchasers segment, keep every single engagement rule identical, but change the purchase condition to placed order at least once overall.
The Math Behind the 80/20 Revenue Split
When you break out your audience this way, you will quickly notice a pattern. Roughly 80% of your total email campaign revenue will consistently come from people who have already bought from you.
In one of our client accounts, a standard campaign generated roughly $10,500 in total sales. When we looked at the breakdown, approximately $8,700 came from existing purchasers, while $1,800 came from engaged subscribers who had never ordered before.
Subscribers do not pay your bills. Customers do.
Your primary objective with non-purchasers is simply converting them into first-time buyers as quickly and cheaply as possible. Once they cross that line, their lifetime value skyrockets, and they move into the profitable 80% bucket.
Why Giving Away 10% Margin Makes Total Sense
Brand owners often push back when I tell them to include a discount in regular campaigns for non-purchasers. They worry about eroding their margins by training people to expect deals.
Here is the thing. You already promised them an incentive on your sign-up form (usually 10% off or free shipping) to get them onto your list in the first place. If they did not convert during the initial welcome flow, they still need a reason to take that first leap.
You do not need to redesign the entire email. Take the exact same campaign, add a small banner or text button that says, "Don't forget to use your 10% welcome code", and send it. You make up that 10% margin sacrifice instantly on their second and third orders, which are bought at full price.
Adjusting Segment Windows for Deliverability
We typically maintain four variations of these purchase-split segments across different timeframes: 30, 60, 90, and 120 days. Which one you use depends entirely on your account health.
If your open rates are sitting in the top 25% of your industry and spam complaints are near zero, you can comfortably send to a 90-day or 120-day engaged segment. You get more reach without hurting your sender reputation.
If your deliverability takes a hit and open rates drop below 20%, you constrict immediately. Move down to 60 days or 30 days of engagement until your engagement metrics recover, then gradually broaden your audience back out.
The Two-Campaign Cloning Workflow
Executing this strategy does not double your workload. It adds about two minutes to your campaign build routine inside Klaviyo.
Build your master campaign with full-price messaging for your engaged purchasers segment. Once that email is approved and ready, clone the campaign, rename it for your non-purchaser segment, and drop your welcome discount reminder into the layout.
You are sending the same high-quality content to both groups, but you are meeting each audience with the exact commercial incentive required to get a transaction over the line.
Final Thoughts
Stop blasting the exact same offer to your entire email list. Segmenting your database by both engagement and purchase history ensures you protect deliverability, stop discounting to existing fans, and aggressively convert new subscribers into long-term customers.
