How to Increase Gmail's Undo Send Time

Give yourself a longer short window to cancel a message immediately after sending.

Quick Answer

In Gmail Settings → General, change the Send cancellation period.

Step by Step

  1. Open the relevant email account or application.
  2. In Gmail Settings → General, change the Send cancellation period.
  3. Review the result carefully before making any permanent deletion, forwarding, or account change.
  4. Confirm the change worked from the mailbox or settings page.

If That Doesn't Work

  • Menu names can differ between web, desktop, mobile, classic, and newer versions of an email application.
  • For business or managed accounts, administrator policies can restrict some settings.
