Review for Mail Merge by Jeffrey Flaker
Rated 4 out of 5 stars
I have to say, this is a very nice addon. However, if Enigmail is installed, it will encrypt every outgoing email with your key only. This makes the message unreadable for the intended recipients. Disable Enigmail with a restart of Thunderbird....run your mail merge, then re-enable Enigmail........
This review is for a previous version of the add-on (3.9.0).To create your own collections, you must have a Mozilla Add-ons account.
