Reactivation Flow: How to Convert Subscribers Who Never Bought

What is a reactivation flow?

A reactivation flow is an automated email for subscribers who signed up, showed some interest, and never bought. It's different from the flows it gets confused with:

Flow	Who it targets	Goal
Welcome series	New subscribers	A first order, fast
Reactivation	Subscribers who engaged at least once but haven't bought after 60 days	One last push for a first order
Win-back	Past customers who haven't reordered	The next order
Sunset	Subscribers with no real engagement for a long time	Protect deliverability by suppressing them

Most brands build the welcome series, the post-purchase flow and browse abandonment. Almost nobody builds the flow for the subscribers who never become customers.

Why do most email subscribers never buy?

For most DTC brands, the majority of subscribers never place an order, often 60 to 80% of the list. The ones who do buy tend to buy early: typically 10 to 30% convert within the first 30 days, and most people who haven't bought by day 60 never will. Exact numbers vary by brand, so check your own.

That means the clock starts the moment someone subscribes. The faster you turn a subscriber into a customer, the lower your real acquisition cost, and the more profitable that signup becomes.

So what happens to everyone who doesn't buy by day 60? At most brands, nothing. They keep getting campaigns until they tune out, and they quietly disappear from your revenue without anyone making one last, deliberate attempt.

What results should you expect from a reactivation flow?

A reactivation flow typically converts 0.5 to 2% of the people who enter it. That sounds low until you remember who they are: subscribers who were going to leave without ever buying.

One example: a brand we work with had 8,400 non-buyers in this segment. The flow converted 1.1% of them into first orders over 90 days. That's 92 new customers who would have churned without ever buying. At a $67 average order value, that's $6,164 in revenue from people who were about to drop off the list anyway, before counting the ones who come back for a second order.

Not life-changing, but not nothing. The flow took 45 minutes to build and hasn't been touched since. You aren't discounting full-price buyers or annoying your best customers. You're giving someone who's about to leave one last good reason to buy.

The reactivation flow blueprint

Step	Setting	Why
Trigger	Added to your main email list	Starts the clock at signup
Time delay	60 days	Gives your welcome series and campaigns time to work first
Flow filter 1	Placed Order zero times over all time	Only people who have never bought
Flow filter 2	Opened Email at least once over all time where Apple Privacy Open is false, OR Clicked Email at least once over all time where Bot Click is false	Proves a real person engaged at some point
Email	Your strongest angle plus the most aggressive offer your margins allow	Answers "why should I buy today?"
Kill switch	Review after 30 days of sends	Protects your sender reputation

How do you build a reactivation flow in Klaviyo?

1. Create a new flow from scratch and set the trigger to your main email list.
2. Add a 60-day time delay as the first step.
3. Add both flow filters from the blueprint above. Filter 2 uses OR between the Opened and Clicked conditions.
4. Add one email after the delay. Lead with your strongest angle and your offer.
5. Use Klaviyo's flow trigger preview to confirm the right people qualify.
6. Set the email live, then add past profiles so your existing non-buyers enter the flow too. Step 6 matters. A list-triggered flow only picks up people as they join the list, so everyone already on it would be skipped. Klaviyo lets you add past profiles to list-triggered flows, placed where they would have fallen in the flow's timeline.

What most brands miss in the engagement filter

The engagement filter is what keeps this flow safe. If someone has never opened or clicked, they're a deliverability liability. Don't email them. This flow only targets people who showed real interest at some point.

The catch: "opened at least once" isn't proof of interest anymore. Apple Mail Privacy Protection can register opens automatically, and security tools click links to scan them. Klaviyo flags both as Apple Privacy Opens and bot clicks. If your filter counts them, you'll mail people who never read a single email, which is the exact audience you're trying to protect your reputation from.

There's a second trap. Klaviyo won't add past profiles to a flow that contains a dynamic coupon. If you plan to back-fill your existing non-buyers, use a static discount code in the email.

What offer should the reactivation email use?

Pair your most compelling angle with the most aggressive offer you can afford. This person is about to leave. The email has to answer one question: why should I buy today?

Work out your unit economics first. Start with the price of a typical first order, subtract product cost, shipping and fees, and the discount has to fit inside what's left. If the deepest discount that keeps the order profitable is 25% off, send 25% off. If you need a threshold to make the math work, like $15 off $50 or more, use that.

Mistakes that break a reactivation flow

• Mailing people who never engaged. No opens and no clicks means no interest, and every send to them chips at your sender reputation.
• Counting machine activity as engagement. Filter out Apple Privacy Opens and bot clicks.
• A weak offer. If you're asking someone who's about to leave, make it worth acting on.
• Using a dynamic coupon and then being unable to add past profiles.
• Sending it to past customers. People who have bought before belong in your win-back flow.
• Leaving it on when it's hurting deliverability.

When should you turn the reactivation flow off?

Turn it off if, over a 30-day period, it drives no revenue and shows either a higher-than-normal bounce rate or a click rate below 0.5%. Check both in the flow's analytics in Klaviyo.

Protecting your sender reputation is worth more than squeezing another $200 out of people who don't want your emails. If the flow stops working, kill it. Nothing else in your program depends on it.

For subscribers who have stopped engaging altogether, a sunset flow is the right tool. For the full set of flows a consumable brand needs, see our Klaviyo flows guide.

FAQ

What's the difference between a reactivation flow and a win-back flow?

A reactivation flow targets subscribers who have never bought. A win-back flow targets past customers who haven't reordered. They need different messages: a non-buyer needs a reason to try you for the first time, while a lapsed customer already knows your product and needs a reason to come back.

When should a reactivation flow trigger?

Around 60 days after someone joins your list. Most subscribers who are going to buy do it within the first 30 to 60 days, so by day 60 your welcome series and campaigns have had their chance. The reactivation email is the last deliberate attempt.

What discount should a reactivation email offer?

The most aggressive discount that keeps a first order profitable. Work it out from your margin after shipping, fees and product cost. If 25% off still makes money, use 25% off. If a straight percentage doesn't work, use a threshold offer like $15 off $50 or more.

Will a reactivation flow hurt my deliverability?

Not if you filter it properly. Only send to people who have engaged at least once, and exclude Apple Privacy Opens and bot clicks from that definition. If the flow shows a click rate below 0.5% or higher-than-normal bounces with no revenue over 30 days, turn it off.

What conversion rate is good for a reactivation flow?

Reactivation flows typically convert 0.5 to 2% of the people who enter. That's low compared with other flows, and that's expected: these subscribers were about to leave without buying. Judge it on the extra first orders, not on the rate.

How many emails should a reactivation flow have?

Start with one. Its job is a single, clear last offer to people close to leaving. One strong email keeps the flow simple to build, easy to measure and quick to switch off if it starts affecting deliverability.
