With the latest version of macOS, you can set an email to send in the future and prevent emails from being sent.
The Apple Mail app has a few new features in macOS Ventura, but there are two that stand out: You can now schedule an email to be sent at a specific day and time, and if you accidentally send an email, you can stop the message before it’s sent. This is how both functions work.
What you’ll need to schedule or unsend an email
To use the new features in Mail, your Mac must be running macOS Ventura or later.

To update to a previous version of macOS, click the Apple icon, select About This Mac, and then click Software Update. Click Update Now to install the update.
Schedule email on macOS Ventura
Open the Mail app, then address and write a new email. When you’re done, click the down arrow next to the Send Message icon at the top of the toolbar. The resulting menu offers three options: Send now, Send at a specified time, and Send later. Click on the second option to select a suggested time. To select another day and time, click on the third option (Figure A).
In the Send later window, select a specific day and time. When done, click the Schedule button (Figure B).
After you schedule your email, a special Send Later folder appears in the left panel as part of your inbox. Click on the scheduled email to view it (Figure C).
At this point, you cannot change or edit the email itself, but you can change the scheduled date and/or time.
Click the Edit button above the email to display the Send Later window. You can now change the date or time. When done, click the Schedule button (Figure D).
When the scheduled time arrives, we will send the email. To check, find it in your Sent folder (Figure E).
Unsend email on macOS Ventura
Apple describes the next feature as Unsend Email, but that’s not quite accurate. The Apple Messaging app allows you to actually retrieve and exchange texts that have already been sent and delivered to the recipient.
The option to cancel the sending of a letter does not work in the same way. When you send an email in Apple Mail, it isn’t sent immediately. By default, it waits 10 seconds before proceeding to the recipient. During this brief second, you can unsend the message to prevent it from being sent.
To try this, write and send an email. The Undo Send option appears at the bottom of the left pane. Click on this option (Figure F).
Your email will stop and appear on the screen for you to edit. Make the necessary changes and resubmit (Figure G).
Want more than 10 seconds to prevent emails from being sent? Click the Mail menu and select Preferences. In the Settings window, select the Mail icon. In the Send section, click the Cancel Send Delay drop-down menu to extend the delay time to 20 or 30 seconds (Figure H).
