Here's How To Undo A Sent Email In Gmail Read more

You clicked send. Oh crap.

When you send a no-take-backs email — maybe an admission to a secret crush, or accidental reply-all — there's an instant pang of regret. It feels like there's no going back.

1. Click the gear icon in the top-right corner of your Gmail window and select Settings from the dropdown menu.
