In this tutorial, we’ll show you how to use the Reminders app on your Mac to remind yourself about specific emails you receive in the Mail app.

The Reminders app on your Mac can be used for more than just typing out your own reminders. You can also use it to remind you to read or reply to specific emails at a particular time or date.
But before you begin, note that the Mail app on macOS Ventura and later already has a built-in Remind Me feature. You can use that, or keep reading to convert your email into an actual reminder.
Method 1: Drag an email and drop it into Reminders
1) Open the Mail app and the Reminders app side by side on your Mac. Then, select the reminder list in the Reminders app and keep it on the screen.
2) Look in the Mail app’s left sidebar and select the email for which you want to be reminded.
3) Drag the email from the Mail app onto the Reminders app screen. Immediately, the subject line of the email will become a reminder entry. You’ll also see a tiny Mail app icon next to it.
4) Take the pointer over the newly created reminder and hit the info button ⓘ. Now, you can set the reminder date, time, and other details.
5) When the reminder time comes, your Mac will send you a notification. You can click the body of the notification banner to launch the Reminders app. From there, click the tiny Mail icon, or the “Shared from Mail” option, which will take you straight to that particular email.
Method 2: Select text and add it to the Reminders app
With this second method, you don’t even need to leave the Mail app! Here’s how to turn your email into a reminder:
1) Open the desired email inside your Mac’s Mail app. Select the text inside the email body or the subject line. After that, right-click and choose Share > Reminders.
2) Hit the info button ⓘ to set the reminder time and date. You can also choose a reminder list, tweak the reminder title, or add a note. With all this done, click Add.
Congratulations! You’ve just set an email-based reminder on your Mac and will be reminded at your designated date or time.
