Many, many times I have been glad to review an email, even 15 minutes before it goes out.
And I use it to schedule emails long times ahead, getting the job done early.
I do suggest an option to send a notice back to me before an item is sent, when it is scheduled for a longer time ahead.

This review is for a previous version of the add-on (6.3).
