Sending Resubscribe Requests
Sometimes subscribers unsubscribe by accident, change their minds, or you've changed something and want to invite them back. Hail Mail's resubscribe request feature lets you safely and respectfully offer unsubscribed contacts the option to rejoin your mailing lists.
What Are Resubscribe Requests?
A resubscribe request is a special email sent to unsubscribed contacts that:
- Explains you'd like them to consider rejoining your mailing list
- Provides a secure link to a resubscription page
- Lets them choose which specific lists to rejoin
- Expires after 7 days for security
- Respects their choice if they ignore it
Important: This feature is only for unsubscribed contacts. It does not work for bounced or complained subscribers (see "Unbouncing and Uncomplaining Subscribers" for those - TODO add links).
