Undo send

Web-composer messages wait 10 seconds before dispatch. Use Undo in the send notification during that window to stop the queued message and return to its draft.

After dispatch, MailMoose cannot recall the email. Provider acceptance does not guarantee inbox delivery.

API sends, agent sends and guided-setup tests send immediately, without this undo window.

Sending requires paid access, sender readiness and quota. If these change before dispatch, a queued message can fail; check its error and saved draft.
