Recall a sent email

Right after you send, Gmail shows an Undo prompt. Press z to trigger it and reopen the draft. The window lasts 5–30s — set it in Settings → General → Undo Send.

Enable keyboard shortcuts

Single-key Gmail actions need shortcuts turned on: Settings → See all settings → General → Keyboard shortcuts on → Save Changes.

FAQ

What is the undo-send shortcut in Gmail?

Press Z immediately after sending (same on Mac and Windows) to recall the message within the undo window.

How long do I have to undo?

5 to 30 seconds, set in Settings → General → Undo Send.

Why doesn't Z work?

The undo window must still be open, and Keyboard shortcuts must be on in Settings.
