Rated 5 out of 5 stars

Please, add to the description. When using on Windows with .CSV, then, after saving the .CSV, it's better to reopen it in a text editor and save it in UTF-8, and after that choose UTF-8 in the add-on's dialog window. Otherwise there may be some charset problems or even errors in sending emails.

This review is for a previous version of the add-on (4.12.0).
