Definition
A goodbye email, also called an unsubscribe confirmation email, is the final message sent to a subscriber after they have unsubscribed from an email list. While the subscriber expects no further communication, a well-crafted goodbye email provides one last opportunity to re-engage them, gather feedback, or leave a positive brand impression. Goodbye emails have typical open rates of 5 to 15 per cent, significantly lower than campaign averages but still reaching a meaningful portion of departing subscribers.
The goodbye email typically includes a survey or feedback request asking why the subscriber is leaving, with options such as too many emails, content not relevant, or no longer interested. It also presents low-commitment alternatives to full unsubscribe, such as pausing emails for 30 or 60 days, reducing frequency to a monthly digest, or changing content preferences. Offering alternatives recovers a portion of subscribers who would otherwise be lost entirely. The email also serves as brand impression management — a memorable goodbye can leave the subscriber with positive feelings that lead to resubscription in the future.
Best Practices
Send the goodbye email immediately after the unsubscribe action is processed. Timing matters because the subscriber's reason for leaving is fresh and they are more likely to provide feedback. A delay of more than a few hours reduces survey response rates.
Offer at least three alternatives to full unsubscribe before processing the removal. Present options such as a weekly digest instead of daily emails, a temporary pause, or a switch to a different content topic. Subscribers who accept an alternative are retained and may re-escalate their engagement later.
Keep the survey short with no more than three to five questions. The first question should be the primary reason for unsubscribing with multiple-choice options. The second can be an open-text field for additional context. Keep optional questions minimal to maximise completion rates.
Design for a positive brand impression even in the farewell. Use warm, appreciative language. Thank the subscriber for their time on the list. Avoid defensive or argumentative tone. A subscriber who leaves with positive feelings is more likely to recommend your brand and may rejoin later.
Include a resubscription link that re-adds the subscriber with a single click. Circumstances change, and a subscriber who unsubscribes today may want to rejoin in three months. A simple reactivation link reduces friction for return. Track resubscription rates as a measure of goodbye email effectiveness.

Frequently Asked Questions
Subscribers who have unsubscribed are naturally less engaged and less likely to open future email. The 5 to 15 per cent open rate represents the subset of departing subscribers who are still somewhat interested in the brand and are willing to provide feedback or consider alternatives.
Too many emails is consistently the most common reason cited across industries, accounting for 40 to 60 per cent of all unsubscribe feedback. Content not relevant is the second most common reason at 20 to 30 per cent. This data should inform frequency and content strategy improvements.
Recovery rates vary, but offering low-commitment alternatives typically retains 5 to 15 per cent of subscribers who would otherwise be lost. The recovery rate is highest when the alternatives are presented prominently and require minimal effort to select.
No. If a subscriber marked a message as spam rather than unsubscribing through the standard mechanism, do not send a goodbye email. Sending additional email to a spam complainant will increase your complaint rate and damage sending reputation. Respect the implicit no-contact signal.
Goodbye emails do not negatively affect sender reputation when sent appropriately. Since the subscriber explicitly unsubscribed, the message may bounce or be filtered, but because it is a single confirmation message, the impact on reputation is negligible. The benefit of feedback and recovery outweighs the minimal reputation cost.
