I use Thunderbird as my Mail client, and have used Mail Merge during December 2018 - January 2019. It worked smoothly.
However, I have tried using Mail Merge for the last 2 days, and it is not working. I have installed the latest version of the Mail Merge tool (5.6.0) yesterday. My Thunderbird version is 60.6.1 (32-bit).
However, despite following instructions for Mail Merge using csv file as the source, not a single mail has gone out.
Can someone help?
