Re-engagement emails: 13 examples, subject lines, and a win-back sequence that works

Marketers work hard and spend a considerable amount of time and resources building effective email marketing campaigns. But do all these efforts always bring the expected results?

Unfortunately, the answer is “no.” According to ZeroBounce’s 2026 Email List Decay Report, 23% of the email addresses it checked in 2025 were invalid or risky. Even valid subscribers may gradually stop engaging. 

This happens for several reasons:

• subscribers change jobs, abandon old email addresses, or move to another country;
• their needs change, so they no longer use the same products or services;
• other brands catch their attention with a more relevant offer;
• the emails no longer match their current interests or expectations;
• some loyal subscribers simply lose interest in your campaigns. Yes, it may happen.

What is a re-engagement email?

A re-engagement email is sent to subscribers who once showed interest in your emails, product, or service but have since stopped responding. They are still subscribed, so you have a chance to remind them why they joined your list and give them a good reason to return.

The desired action depends on your business. 

You may want the recipient to:

• click through to new content;
• make another purchase;
• return to their account;
• restart a trial;
• reply or update their preferences.

Sometimes one email is enough. In other cases, you may need a short sequence that starts with a friendly reminder and ends with a final subscription check. People who have already unsubscribed do not belong in either campaign.

Re-engagement vs. win-back vs. reactivation

These terms are often used interchangeably, but they do not always describe the same audience. Here is the easiest way to separate them.

 

For example, Klaviyo describes a win-back flow as a series for customers who purchased before but have not returned within their usual buying cycle. Other platforms may use a different name. What matters most is not the label but the action that will count as a successful return.

Why re-engagement emails matter

You might think it is easier to find new subscribers than to win the lost ones back. But people who already know your brand do not need the same introduction as someone seeing it for the first time.

A good re-engagement campaign helps you:

• bring interested subscribers or customers back;
• learn which content, products, or offers still appeal to them;
• collect updated preferences and feedback;
• identify contacts who should stop receiving regular campaigns.

Not everyone will return, and that is fine. A clear “no” is still useful because it keeps you from sending email after email to someone who is no longer interested.

The deliverability angle

Sending to inactive subscribers for months may look harmless, especially when they do not unsubscribe. In reality, silence is not always a positive signal. Low engagement, spam complaints, and invalid addresses can make it harder for your future campaigns to reach the inbox.

Mailbox providers also leave little room for complaints. Yahoo asks bulk senders to keep their spam complaint rate below 0.3%. This is one more reason not to send endless “We miss you” emails to the same dormant audience.

A re-engagement campaign gives subscribers one last clear choice. Those who respond return to the appropriate active segment. Those who remain inactive can be suppressed or archived after the final email and grace period.

How to know when it’s time (defining “inactive”)

There is no universal 30-, 60-, or 90-day rule. The right period depends on how often people normally interact with your business.

Let’s imagine that a subscriber has not clicked on an email for two months but placed an order last week. They may be inactive in your newsletter, but they are clearly not an inactive customer. This is why email activity should be checked against the rest of the customer journey.

The most useful inactive signals depend on the business:

• for a newsletter, no clicks across several editions;
• for eCommerce, no purchase after the normal reorder period;
• for SaaS, no login or important product action;
• for a subscription service, no renewal or a drop in usage;
• for B2B, no reply, meeting, website return, or CRM activity.

Choose the signal that reflects the relationship you want to restore. An open alone is rarely enough.

Opens vs. clicks after Mail Privacy Protection

Opens used to be the easiest way to identify inactive subscribers. Today, they can give you a misleading picture.

Apple Mail Privacy Protection prevents senders from reliably seeing whether a protected recipient opened an email. Apple may download remote content without confirming that the person actually read the message. As a result, an inactive subscriber can appear active in an open-based report.

Clicks require intentional action, so they are usually a stronger signal. Still, do not look at clicks in isolation. Combine them with purchases, replies, logins, website visits, preference updates, and product activity. Opens can remain a supporting metric, especially when your platform identifies an MPP-affected activity, but they should not decide on their own who enters a re-engagement campaign.

Timing and frequency: When to send

Send the first email after the recipient has passed your normal engagement, purchase, or product-use cycle—plus a reasonable grace period.

 

The goal is to reach people after their usual activity has stopped but before they completely forget why they subscribed. Too early, and you may contact someone who is simply taking a short break. Too late, and even your brand name may no longer look familiar.

How long to wait before the first email

Start with the behavior of your active audience. A weekly publication may act after several missed newsletters. A store selling shampoo can use the normal reorder period. A furniture retailer will naturally need a much longer window.

Klaviyo’s win-back guidance recommends sending the first email slightly after the company’s average buying cycle. The same logic works for other businesses: find the usual interval between meaningful actions, add a short grace period, and test the result.

Do not choose 30, 60, or 90 days simply because another brand uses that number. Their customers may behave very differently from yours.

How to space the sequence

Note: Do not send all emails on the same day. Let people recollect who you are, then give them time to decide whether they want to return.

Each email should also have its own job. The first can remind recipients why they subscribed. The next may show what has changed, ask for feedback, or present a relevant offer. The final email can ask them to stay subscribed, update their preferences, or leave the list.

The spacing should match your usual frequency. If you normally send one email a month, three re-engagement emails in one week will feel out of place. Klaviyo’s current sunset-flow guidance uses a three-day grace period for daily sending and suggests 7-10 days for less frequent programs. Treat these numbers as a starting point, not as a rule for every campaign.

Remove recipients from the sequence as soon as they click, purchase, reply, log in, update their preferences, unsubscribe, complain, or bounce.

How to segment inactive subscribers

Before starting a re-engagement email campaign, make sure that you know your audience well. One large “inactive” segment can contain very different people: former customers, newsletter readers, trial users, and active customers who simply do not click marketing emails.

Start with one inactive condition and one action you want to restore. 

Then narrow the audience using information such as:

• previous purchases or product interests;
• subscription type and content preferences;
• account, website, or product activity;
• customer value and purchase frequency;
• the point at which engagement stopped.

Exclude people when the message is irrelevant or mistimed. This includes new subscribers without enough history, recent purchasers, active product users, recipients in conflicting flows, unsubscribed contacts, complaints, and hard bounces.

The goal is not to create the largest possible segment. It is to send a relevant reason to return to people who may still want one.

13 re-engagement email examples

The following re-engagement email examples are grouped by campaign job, not ranked by quality. Each shows how one message pattern can lead recipients toward a specific action.

1. Personalization

eBay’s win-back email greets the recipient personally followed by four product recommendations based on likely interests. This creates several clear return points without sending the recipient into the full marketplace. A feedback link also offers an action for people who are not ready to shop, showing that personalization can do more than insert a first name.

2. Blame the inbox

ARRIVAL’s 2025 email acknowledges that busy inboxes make messages easy to miss, without blaming the recipient. It then provides simple steps for finding future emails and reconnecting with the sender. Inbox-placement instructions can support re-engagement, but they cannot replace proper authentication, recognizable sender details, or content that gives recipients a reason to keep opening emails.

3. Show emotion (GIF)

Doppler’s 2025 re-engagement email asks “Are you still there?” and uses a GIF to reinforce the emotional tone. The animation attracts attention without carrying the whole message, so the email still makes sense when images are blocked. A short survey gives recipients a deliberate reason to click while helping Doppler learn why their interest declined.

4. Keep it simple

Michael Kors’ 2025 reactivation email uses a restrained black-and-white design built around the headline “Let’s stay together.” The recipient sees one dominant message and one clear action rather than another product-heavy promotion. This short format suits a final interest check, where the main purpose is to confirm whether the recipient still wants the brand’s emails.

5. Show what they’re missing

Saks Fifth Avenue’s 2025 email invites the recipient to discover what has arrived since their last visit. Its product selection focuses on a designer connected to the recipient’s previous interests instead of presenting the full catalog. This makes the “what’s new” angle more specific and gives the recipient a familiar starting point for returning to the store.

6. Show your generosity

YouTube TV’s 2025 win-back email places subscription benefits alongside clearly stated savings, reminding former customers what they receive and what the return offer costs. The CTA takes recipients directly to reactivation, keeping the next step clear. An incentive is optional.

7. Give them an alternative

Canva’s 2026 preference email allows recipients to stop Canva Create updates without affecting their other Canva subscriptions. This campaign-level choice is more precise than forcing an all-or-nothing decision. Recipients can remove an email category that no longer interests them, while Canva preserves the parts of the relationship they still value and records a clear preference.

8. Show off your new look

Google’s Gemini re-engagement email uses “Check out what’s new with Gemini” as its reason to return. Instead of relying on a generic “we miss you” message, the email introduces product developments that appeared during the recipient’s absence. This approach works when the updates are substantial enough to change how the recipient might use or assess the product.

9. Extend the trial

Shopify’s 2026 trial email reduces the financial barrier to returning with a $1 trial extension. It also connects subscription credits to sales, giving the offer a business benefit beyond its low entry price. Pricing details and conditions remain visible, helping recipients understand what they are accepting before they restart the trial or choose a paid plan.

10. Make it funny

Birddogs’ 2024 re-engagement email uses illustrations and humor consistent with the company’s established voice. The playful presentation attracts attention, but the featured products and return action remain easy to understand. The email also avoids disguising itself as a personal reply or system notice, which keeps the joke separate from the information recipients need to make a decision.

11. Update preferences

In our guide to retention emails, we shared an example from Levi’s that lets recipients choose between “Keep me subscribed” and “Unsubscribe.” This turns continued interest into a measurable action instead of counting an open as confirmation. The visible exit option also lets recipients make a clear decision without having to search the footer or a complicated preference page.

12. Monthly digest

RealSelf’s 2025 editorial email organizes a timely topic into a scannable digest supported by expert comments and practical treatment details. The available example is not confirmed as a campaign for inactive subscribers. Still, the format can support re-engagement when sent to a defined inactive segment because the digest itself supplies a current, useful reason to return.

13. Run a re-engagement sequence

Stripo’s seven-day reactivation case targeted subscribers who had been on the list for at least 90 days without purchasing and reused seven emails that had performed well before. Daily delivery generated 45% more revenue per subscriber than every-other-day sending and a 6% lift over the control group, without an unsubscribe spike. These results describe one tested audience and should not turn seven daily emails into a default sequence for every brand.

Make two or three emails in the series.

Stay polite.

Before starting a re-engagement email marketing campaign, make sure that you know your audience well.

Use Stripo reactivation templates to save time.

Re-engagement email subject lines

Your subject line has one job: give inactive subscribers a reason to open the email. “We miss you” may sound friendly, but it says more about the sender than about what the recipient will find inside.

Choose an angle that matches the message and the action you want the recipient to take.

 

Real brands take the same approaches. eBay used “If the 90s can make a comeback, so can you,” Doppler asked recipients to help improve its emails, and Levi’s went with the direct “Don’t let this be goodbye.”

The subject lines in Email Love’s 2026 re-engagement collection average 31 characters, while 30% use discount language. These figures describe that specific gallery, not a rule for every campaign. A discount may help, but it is far from the only reason to return.

Keep the promise honest. Gmail prohibits using Re: or Fwd: unless the message is an actual reply or forward.

How to A/B test subject lines

Do not test two random ideas and simply choose the one with more opens. Start with a clear question, such as whether inactive subscribers respond better to new value or a direct subscription check.

Then follow four steps:

1. Define one hypothesis and the result that would support it.
2. Change only the subject line while keeping the sender, preview text, content, and timing the same.
3. Randomly split the same inactive segment between the two variants.
4. Compare clicks, conversions, unsubscribes, and complaints alongside opens.

Opens can still provide supporting information, but Apple Mail Privacy Protection makes them less reliable. If one subject line gets more opens but the other brings more purchases, replies, or logins, the second one has done the more important job.

How to build a re-engagement sequence

Make two or three emails in the series. This is enough to try different return angles without repeatedly contacting people who have already stopped responding.

Each email should have one clear job.

 

This structure is only a starting point. One email may be enough for a final interest check, while a longer sequence needs testing. More emails do not automatically mean more recovered subscribers.

Before you activate the sequence, decide:

• which inactivity condition starts it;
• who must be excluded;
• how much time passes between emails;
• which action immediately removes a recipient;
• how long the final grace period lasts;
• what happens to nonresponders.

Exit rules are particularly important. If someone purchases after Email 1, do not send Email 2 saying that you are still waiting for them to return. The same applies to clicks, replies, logins, preference updates, unsubscribes, complaints, and hard bounces.

Stripo helps you create emails, add merge tags and fallback values, preview the results, validate URLs, run email client tests, and export the finished templates. Your ESP or CRM handles the segment, trigger, delays, sending, exit events, and suppression.

Best practices and common mistakes

There is no secret element that makes every inactive subscriber return. Most successful re-engagement emails simply make the decision easy and avoid giving the recipient five different things to do.

The table below shows where a useful idea can quickly turn into a common mistake.

 

Before sending, check how the email looks on mobile and in dark mode. Test every link, add a static fallback for GIFs, and keep the main message in readable HTML rather than placing everything inside a single large image.

Stay polite. The recipient does not owe the brand another purchase, click, or reply. Your task is to give them a relevant choice, not to make them feel guilty for leaving.

What to do when re-engagement fails (list hygiene and suppression)

Sometimes, even a good subject line, useful offer, and clear CTA do not work. Allow the planned grace period after the final email, then stop sending regular campaigns to recipients who remain inactive.

The exact action depends on your ESP. Klaviyo recommends running long-term inactive profiles through a sunset flow before suppressing nonresponders. Mailchimp allows inactive contacts to be archived without losing their data, and archived contacts can be restored later.

Keep the following distinction in mind:

• inactivity means that the recipient has stopped taking the chosen actions;
• suppression or archive removes the contact from regular marketing sends;
• unsubscribe is the recipient’s explicit decision to stop receiving marketing emails;
• deletion permanently removes data and should not be treated as the default list-cleaning action.

Do not mark inactive subscribers as unsubscribed if they did not opt out. At the same time, never send another marketing reactivation request after an actual unsubscribe.

Measuring re-engagement success

An open tells you that the subject line may have attracted attention. It does not tell you whether the subscriber has returned.

Start with the action chosen before the campaign:

• purchases, revenue, renewals, or trial restarts for commercial campaigns;
• clicks and returning website visits for content campaigns;
• logins or core product actions for SaaS;
• replies or booked meetings for B2B;
• preference confirmations for subscription checks.

Then watch list-health metrics such as unsubscribes, complaints, and hard bounces. A campaign that produces a few sales but causes a sharp complaint increase may create more problems than it solves.

For context, Omnisend’s lapsed-purchase automation data report a 33.00% open rate, 1.96% click-to-send rate, 0.52% conversion rate, and 26.74% click-to-conversion rate. These are platform-specific figures, not universal targets. MPP also limits direct open-rate comparisons.

If possible, keep a small randomized control group that does not receive the sequence. This shows how many recipients would have returned on their own and how much additional activity the campaign actually produced.

Re-engagement for B2B/sales pipelines

B2B re-engagement works a little differently. The recipient may not need to purchase anything after opening the email. A reply, meeting, reopened opportunity, or return to a pricing page can be a much more valuable signal.

The first step is to define inactivity around the sales process. Useful signals may include:

• no reply after the last conversation;
• no meeting or CRM activity;
• no return visit to an important website page;
• no product login or trial action;
• no movement in the opportunity for a defined period.

Do not place every quiet lead into the same automated sequence. Someone who downloaded one guide six months ago needs a different message from a former customer or a decision-maker involved in an open deal.

A B2B re-engagement email can refer to the previous conversation, share an update connected to the recipient’s role, ask whether the project is still relevant, or offer an easier next step. “Would you like to continue?” is often more suitable than another product-heavy promotion.

Marketing and sales also need shared exit rules. Exclude contacts with active opportunities, recent replies, scheduled meetings, open support cases, or current conversations with a sales representative. Otherwise, automation may send a “We haven’t heard from you” email while someone on your team is already speaking with them.

Wrapping up

Define inactivity before deciding what the email should say. Test the first-send timing and sequence length against the recipient’s actual behavior. Return responders to the appropriate active segment, then suppress or archive nonresponders after the final grace period. Stripo supports email creation, preview, testing, and export throughout this process.

FAQ

1. What is a re-engagement email?

A re-engagement email is a targeted message sent to an inactive subscriber who can still receive marketing communications. It asks them to return, confirm their preferences, or unsubscribe.

2. When should you send a re-engagement email?

Send one after the recipient has passed the brand’s usual email-engagement, purchase, or product-use interval, allowing enough additional time to distinguish inactivity from a temporary pause.

3. How many emails should a win-back sequence have?

One to three emails are a sensible starting point. Longer sequences need frequency limits and measured results; Stripo’s seven-email reactivation case is a tested exception, not a general recommendation.

4. What is a good open rate for re-engagement emails?

No single open rate applies to every campaign; 33% for its lapsed-purchase automations, but this is platform-specific; clicks, conversions, and revenue provide stronger evidence.

5. Do re-engagement emails hurt deliverability?

Yes, if brands repeatedly contact large dormant segments. Narrow eligibility rules, sending limits, immediate exit events, and suppression after the final attempt help control the deliverability risk.

6. When should you remove inactive subscribers?

Suppress or archive inactive subscribers after the planned final email and grace period if they do not complete the target action. Do not treat permanent deletion as the default.

7. What is the difference between re-engagement and win-back emails?

Re-engagement emails usually target subscribers who stopped interacting with marketing or the product. Win-back emails typically target former customers who stopped purchasing, renewing, or paying.

8. What are good re-engagement email subject lines?

Good subject lines state a truthful reason to return, such as new value, a feedback request, a genuine incentive, or a clear decision about future emails.
