Do you ever want to email something to yourself so that you can remember it later? It happens to me all the time especially when I am on a mobile phone. For instance, if I come across a cool site that I would want to check out later from the desktop, I just send the URL to my own email account. If I have an idea for a blog or need to remember something, I jot it down in a message and email it to myself. Now there are quite a few apps that can help you schedule email based reminders, including Google Calendar, but if you prefer to have something really simple that you can use from your email program itself and one that requires no setup, check out FollowUpThen.
