Unsending an email after it’s been sent can be tricky. If you are using a service like Gmail, you can enable the “Undo Send” feature, which allows you to recall an email within a specific time frame (up to 30 seconds) after sending. However, if the email has already been delivered, it’s not possible to unsend it without the recipient knowing.
