Using AI to write email? Give yourself longer to hit Undo in Gmail.

You hit Send on an AI-assisted reply, then spot the wrong customer's name. If you're using Gmail on a computer, there's a small setting worth changing before that happens. Open Settings → See all settings. Beside Undo Send, choose a send cancellation period, then click Save changes at the bottom. Google's existing guide lists 5, 10, 20 or 30 seconds. I'd choose 30. After sending, the Undo link appears beside ‘Message sent’ at the bottom left. Click it immediately if something is wrong. This is a short cancellation window, not a way to retrieve an email whenever you notice a mistake later. I'd still read the recipient and any promises in the draft before sending. The extra seconds are for the mistake you notice just after the click. This is a setting suggested from Google's documentation, not a claim that I've tested an AI email tool or that the window covers messages sent by a separate service.
