This is a very interesting service. Let’s say you send an email to someone about subject X, you can also set up a reminder about subject X to be sent out in two days, two weeks, even two months. This service lets you do it by simply using the “CC” or “BCC” field.
If you use the “CC” field, the reminder will come to both of you. The “BCC” field will only remind the recipient. There are some other features here and you’ll probably find a variety of ways to use it.
The service is free and is exceptionally simple to use.
