     - The email subject to send with the reminder.

+- Review (Invited) - sent when a reviewer has been invited but not accepted a review request.
+- Review (Accepted) - sent when a reviewer has accepted a review request but not yet completed it.
+- Revision - Sent to authors with active revision requests.
+
+Review reminders, both invited and accepted, are sent based on the review assignment due date set by the editor. Revision reminders are sent based on the revision request due date set by the editor. You can set reminders to be sent either before or after the set due date.
