Whatever the aim and purpose, SendTools lets you specify an exact sending time in the future (you cannot send emails in the past; I tried; changing the computer's clock works, though). When you click "Send", SendTools places the message in a "Scheduled" folder, whence it is delivered at the time you set.
Everything works in a clear and uncomplicated manner — except for actually setting the time, perhaps. Using precise mouse commands, you have to click at the various date fields, in the upper half to increase and targeting the lower half to discount. If you don't have to do it often, I imagine this to be fun.
While SendTools sends individual emails in the future automatically, you cannot schedule messages to be repeated at an interval. The option to edit messages after they have been scheduled (but before delivery time has come) might be nice, too.
