Definition
💡 One-click unsubscribe is a link or button contained in an email header allowing the recipient to remove themself from future marketing messages. While similar to an unsubscribe link, one-click unsubscribe automatically removes the recipient from the mailing list without any further actions like confirming on a web page.
How does it work?
When an email recipient uses the one-click unsubscribe option in a message, they are automatically removed from future emails. This applies to promotional and marketing emails, not transactional or relationship communications.
