Have you ever regretted an email immediately after you’ve sent it and wish you could grab it back from the ether before it gets to your recipients? We all have. And here’s the good news: you can.

Both Gmail and Outlook let you unsend an email for a short period of time, but the trick is you need to have the feature enabled first. Once enabled, “Undo Send” will allow you a brief window when you can successfully retract your message before it reaches its end destination. The “Undo Send” feature doesn’t retrieve your email from other people’s inbox; it merely delays sending your email, giving you the chance to change your mind before it’s too late.

Outlook has a “Recall Message” feature that can delete an email sitting in the recipient’s email inbox. However, it only works if you are sending a message to someone using the same Microsoft Exchange server (i.e. someone within your company) or to another person with a Microsoft 365 account.
