If Mail Merge is not yet translated into your own language and if you are familiar with both Thunderbird and Mail Merge, then please contact me by email: There is no money involved, but an honorable mention in the "Hall of Fame" a.k.a. Call for Help with the Translations: Mail Merge is already fully translated into some languages (English, German, Czech, Spanish, French, Hungarian, Italian, Dutch, Polish, Romanian and Turkish). This change is caused by the new "pills" in Thunderbird 78.

See: Changelog - Variable(s) in the To field in Thunderbird 78 / 91 / 102: You must hit "Enter" or "Tab" once you have added the variable(s) in the To field.

See: Changelog - Attachments in Thunderbird 102: There is an important change in the way (individual) attachments are specified in the Mail Merge Dialog. Most of the code has been ported from a MailExtension "Experiment" to a "Pure" MailExtension. Thunderbird 91: Mail Merge 8.4.0 is fully compatible with Thunderbird 91! - Thunderbird 102: (Recommended) Mail Merge 9.4.0 is fully compatible with Thunderbird 102! - IMPORTANT: Mail Merge 9.0.0 is a major update from the previous version 8.4.0.
