Note: Undo Send works by holding the email in the Outbox folder on your account, for a time you specify. After that time, the message is delivered to the recipient and cannot be recalled.

How to undo a sent email

Note: Some email clients, like Gmail and Outlook, already have a similar feature built-in. This is why Mailbutler's Undo Send feature is currently only available for Apple Mail.

You have multiple ways of stopping a message from being sent.

1. Compose your message and click on the Send button.

2. A message will pop up from your menu bar, giving you the option to recall your email or to send it immediately. Click on the Undo Send button to recall or edit your email. Click on the Send button to send the email without further delay.

3. In your Mail Preferences you can choose whether you want to have the Undo Send icon in your menu bar always, only when necessary or never (see here for more information). If you select never, you cannot recall a message from your menu bar. Instead, you can recall a message from inside Apple Mail. Click on the Undo Send button to make the Undo Send message pop up.

If you send multiple emails in succession, scroll down in the Undo Send message to view all emails you can undo.

4. You can also recall an email from your Outbox. Your delayed emails are temporarily saved in your Outbox. Go to your Outbox and click Undo Send or Send Now in the green banner at the top.
