Cannot give enough kudos to this add-on. It is simply brilliant. The ability to time when I send an email has been extremely useful. The natural language recognition works great.
This review is for a previous version of the add-on (5.0).For the record, the natural language recognition in Send Later is part of a third-party library, SugarJS, written by Andrew Plummer. So he gets the credit for that. :-)
