Re-engagement campaigns target subscribers or customers who have stopped buying or opening your emails, aiming to bring them back before they are lost entirely.
Done well, it recovers revenue from an audience that already knows your brand, at a fraction of the cost of acquiring new customers. Done poorly, it damages deliverability, conditions subscribers to expect a discount before engaging, and suppresses contacts who would’ve come back on their own.
The difference between the two is almost always in the setup: How you define a lapsed customer, how you structure the sequence, and when you decide to let go.
If you want help building this from the ground up, our Email Marketing Services include a re-engagement flow setup in every program we build.

How to Define a Lapsed Customer for Your Specific Brand
The most common mistake in re-engagement is using a default 90-day lapse threshold, meaning the point at which a subscriber is considered lapsed, without checking whether it matches how your customers actually buy. A brand selling skincare with a 45-day repurchase cycle has a very different lapse window than a brand selling furniture where a second purchase might take two years.
How to Set Your Own Lapse Threshold:
- Pull the Time Between First and Second Purchase for Returning Customers – This is your natural repurchase window. A lapsed customer is someone who has gone meaningfully past that window without buying again.
- Avoid Re-Engaging Customers Still in the Normal Repurchase Cycle – If your average repurchase window is 45 days, your lapse threshold might be 60-75 days. If it’s 90 days, then your threshold might be 120 days.
- Set Separate Thresholds for Subscribers Who Have Never Purchased – A subscriber who joined your list, never bought, and hasn’t opened an email in 60 days needs a different approach than a customer who bought three times and went quiet.
According to Klaviyo data, win-back emails sent 30-45 days after a lapse tend to convert at higher rates than those sent at 90 days, because brand recall and purchase intent decline with time.
Most brands wait too long and miss their chance.
How to Structure a Re-engagement Email Sequence
Using an email sequence with 3-4 emails tends to outperform a single re-engagement email because each email can do a different job.
Here’s How to Structure It:
| Timing | Main Job | What to Avoid | |
|---|---|---|---|
| Email 1 | At lapse threshold |
| Don’t lead with “We miss you!” Reference something specific about their history with the brand instead. |
| Email 2 | 3-5 days later |
| Don’t just repeat Email 1. This email should feel like a natural follow-on, not another version of the first. |
| Email 3 | 5-7 days later |
| Don’t make the discount too large. A significant offer at this stage signals that waiting is always rewarded. |
| Email 4 (optional) | 7-10 days later |
| Don’t use guilt or pressure. A clean, honest message performs better than manufactured urgency. |
Genuinely interested subscribers often return after Email 1 or 2 without needing an incentive, which protects your brand’s margin on those reactivations while reserving the offer for contacts who need it.
When to Offer a Discount and When Not To
Leading a re-engagement campaign with a discount can condition lapsed customers to disengage intentionally, expecting an offer every time.
How to Use Incentives Without Creating That Pattern:
- Discounts Work Best as a Last Resort, Not A First Move – Reserve them for Email 3 or 4, after your initial value-led emails have had a chance to convert. This way, you only discount the contacts who genuinely needed the incentive.
- Make the Offer Product-Specific Rather Than Sitewide – A discount on the category a customer previously bought from is more relevant than a blanket sale. It signals that you created the offer with them and their preferences in mind.
- Consider Alternatives to a Discount – Free shipping, early access to a new product, or a loyalty reward can re-engage lapsed customers without conditioning them to expect price reductions. These work particularly well for brands where discounting undermines the premium positioning of their products
When to Stop Sending and Suppress Lapsed Contacts
Continuing to send to contacts who have not responded to a full re-engagement sequence damages sender reputation because inbox providers track low engagement as a signal that your emails are unwanted. Suppression keeps your deliverability healthy and your engagement rates meaningful.
The Practical Suppression Framework:
- Move contacts who don’t open or click any email in the sequence to a suppressed segment and remove them from regular campaign sends.
- Suppressed contacts can remain on your list for transactional emails if they have purchase history, but should not receive promotional campaigns.
- Run a re-engagement attempt once per year for suppressed contacts who were previously high-value buyers. For contacts who never purchased, one attempt is enough.
- Suppress hard bounces and spam complaints immediately, regardless of history.

How to Measure Whether Your Re-Engagement Campaign Works
The metrics that matter for re-engagement are different from regular campaign metrics. You should know what to look out for to determine whether your campaign is getting results.
Here’s What to Track:
- Reactivation Rate – The percentage of lapsed contacts who purchase within 30 days of entering the sequence. Average reactivation tends to sit between 12-20% based on 2025 to 2026 ecommerce data, with variations depending on brand strength, offer quality, and timing.
- Revenue Per Recipient – Total revenue generated divided by the number of contacts who entered the flow. This is the honest bottom line because it accounts for everyone in the sequence, not just those who converted.
- Click rate Per Email – Tracking this at the individual email level tells you where in the sequence subscribers are engaging, which helps you refine timing and content for the future.
- Suppression Rate – A very high suppression rate may indicate your lapse threshold is too late and you are reaching contacts who have already moved on entirely.
Frequently Asked Questions (FAQs)
Q1. What is an email re-engagement campaign?
An automated sequence sent to subscribers or customers who have stopped opening, clicking, or purchasing. It uses brand reminders, value-led content, and a time-limited incentive as a last resort to bring them back before they disengage permanently.
Q2. How do you define a lapsed customer for a re-engagement campaign?
Pull the average time between first and second purchase for customers who do return, then add a buffer. If your repurchase window is 45 days, set your lapse threshold around 60 to 75 days. Most brands default to 90 days, which is often too late for shorter repurchase cycles.
Q3. How many emails should a re-engagement sequence have?
Three to four emails tends to outperform a single send because each email can do a different job. The first reintroduces the brand, the second adds value, the third introduces an incentive if needed, and the fourth is an optional last-chance message before suppression.
Q4. Should you offer a discount in a re-engagement email?
Leading with a discount in the first email tends to condition subscribers to expect offers before re-engaging. It generally works better as a last resort in Email 3 or 4, after value-led emails have had a chance to convert. When you do use one, making it product-specific rather than sitewide tends to feel more relevant.
Q5. When should you suppress lapsed email subscribers?
After they complete the full sequence without responding.
For previously high-value buyers, one re-engagement attempt per year is reasonable. For contacts who never purchased, one attempt is enough before permanent suppression.
