Not every email needs to be — or even should be — sent immediately, and that's why many mail apps offer a way to send email at a later time. Starting with iOS 16, Apple allows you to schedule an email for later on your iPhone using the standard Mail app. This way, for example, you can send email during normal business hours even if you drafted it late at night or over the weekend.
How to schedule an email on the iPhone
To schedule an email, your iPhone needs to be running iOS 16 or later. Check your version of iOS and update your iPhone if needed. After that, you'll be ready to schedule emails for later.
1. Start the Mail app.
2. Draft your email the way you normally would, complete with the recipient, subject, and message.
3. When you are done with the email and ready to send it, tap and hold the Send icon (the big blue arrow). You'll see a pop-up menu.
4. Choose when you want to send the message.
Apple gives you a few quick-pick choices, including Send 9:00 PM Tonight and Send 8:00 AM Tomorrow. If you want to choose a custom time, tap Send Later… and you can choose the date and time from a calendar view, then tap Done.
How to change the scheduled time before it's sent
After you choose your time, the email will be stored in the Mail app's Send Later mailbox. If you need to change when the email is being sent, you can adjust the send time right until the last moment.
1. In the Mail app, tap the Back arrow as needed to see the Mailboxes page.
2. Tap Send Later, then tap the scheduled email you want to edit.
3. In the gray bar at the top of the message that shows when the email will be sent, tap Edit.
4. Change the send time and then tap Done.
