Check the Enable two-step unsubscribe box to take a recipient who clicks an unsubscribe link to a web page where he needs to click a secondary link to actually unsubscribe. Without this setting, clicking the original link in the email will unsubscribe him. This feature enforces a two-step unsubscribe process versus a one-step unsubscribe process.
- Subscribers sometimes click the unsubscribe link unintentionally. When this feature is turned on, clicking the link in the email will not immediately unsubscribe a recipient.
- Some anti-spam systems scan the body of an email and programmatically visit every URL in the email, thus triggering the click of the unsubscribe link. The two-step confirmation process will prevent software from automatically unsubscribing a recipient.
