✉️ Overview

Mailbird offers a convenient “Undo Send” feature, allowing you to cancel an email shortly after sending it. This is especially useful when you notice a mistake or change your mind at the last second.

With this feature enabled, you’ll have a short window of time to stop the email before it’s delivered.

⚙️ How to Enable and Configure “Undo Send”

Follow these steps to set up the feature:

  1. Open the Mailbird menu in the top-left corner (three horizontal lines)
  2. Click on Settings
  3. Navigate to the Composing tab
  4. Scroll down to “Undo send period”
  5. Select your preferred time window (between 5 and 30 seconds)

This setting determines how long you have to cancel a sent email.

↩️ How to Undo a Sent Email

After sending an email, you’ll see a small pop-up notification at the bottom of your inbox.

  • Click Undo within the visible time window to cancel sending
  • The pop-up will only remain visible for the duration you selected

If you don’t click Undo in time, the email will be sent as usual

📝 What Happens After You Undo

If you cancel sending using Undo:

  • The email will not be delivered to the recipient
  • A copy of the email will be saved in your Drafts folder
  • You can review, edit, and resend it whenever you’re ready

⏱️ Important Notes

  • The Undo option is only available for the configured time window (5–30 seconds)
  • Once that time expires, the email cannot be recalled
  • This feature works by delaying the send, not retrieving emails after delivery
