I just found out that I can't send a merged mail from Word via Thunderbird. I was devastated because I didn't have much time left to accomplish this mail out. It took much less than an hour to find this add-on, install it, configure the mail and send it out. I'm glad to know, that I can do this now without the need to use Word. Where can I send my donation to?
This review is for a previous version of the add-on (4.3.0).
