Unsend an email in Gmail for as long as 30 seconds! Here's how
You may well have often sent a Gmail email to the wrong person or mails having some errors. Even if you usually have excellent email habits, like always double-checking who's in the "To" field, it is natural to occasionally forget to link a file or notice misspelled names after hitting “Send.” However, once you click on send, you cannot delete the email, but, you can undo it to fix the error.
