✉️ 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:
- Open the Mailbird menu in the top-left corner (three horizontal lines)
- Click on Settings
- Navigate to the Composing tab
- Scroll down to “Undo send period”
- 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
