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........
