Rated 3 out of 5 stars

At first I couldn't get it to pick up any fields until I changed the perser setting from Nunjucks to Legacy. Then it picked up {{First Name}} in the body of the email but not the primary email address in the To: field. Then I read another review that says you have to hit the Enter key after typing {{Primary Email}} and that worked.

Overall I find it less easy to use than the original Mail Merge 8.4.0 by Alexander Bergmann and now Mail Merge 8.4.0 now has a preview feature so I don't think that Mail MergeP offers any advantages

This review is for a previous version of the add-on (2.5).
