With reminders, you can receive a notification if your email goes unopened for 48 hours. This gives you a heads up that the email you're using didn’t reach your intended recipient. It could be that the recipient is busy, is away, or worse, is ignoring your emails. Whatever the case, an email notification will alert you that your message has NOT been read. This knowledge lets you take the next appropriate steps because your current email recipient may not be your best point of contact.
