Excellent in every way - functionality, ease of use and documentation.

Been using it with Send Later extension once every month to send 500 to 700 customized emails for more than a year (non-profit purpose) and it has never failed, never crashed. It's actually a pleasure to see it working - merging, queuing and sending emails one by one in a very smooth fashion.

Big thanks to the developer for putting in the time and effort to develop and maintain it. The world is a better place because of people like you.

This extension deserves 10 stars out of 5.

I have had hard time writing the same email individually.
It took me one hour and above to understand usage.^^; as a novice.

It took me about half an hour to figure this out, but it is actually very easy to use with an address book. I just create an email with multiple email addresses as usual and then run Mail Merge and it generates a personalized email for each recipient.

Very happy with this tool. A few things can be a little tricky, but once you understand how to configure your email and merge file, it worked perfectly.

We've been using Mail Merge for several years to manage the distribution of press releases - and it has never failed. It's versatile, with conditional processing, and enables us to use csvs exported from spreadhseets of contacts.

It's a superbly well built and useful add-on.

Highly recommened

Since 2017-08-29 version 4.9.0 is broken on Seamonkey 2.48. The current version 4.9.1 works as fine as the former version 4.8.0. Thanks to the author for his fast reaction.

Attention! With address book you need to insert all email addresses to "To:" manually!

With csv you need a complete CSV-file with first line = header line, eg. First,Last,xmail, .... then you have to insert to "To:" {{xmail}}

I lost a lot time with that, the autor explained it to me by email. :)

Concerning the claim that there is no way to use special language characters in a .csv-file: If you change the character set to "Windows-1252" in the 'Mail Merge' window, you can use special characters like ü, ä, ö as well. Excellent add-on, it's saving me tons of time.

Didn't work the first time I installed. I spent a frustrating couple of hours trying to find MY errors. Removing, restarting the PC and reinstalling fixed it, it would seem, as the same data set worked perfectly afterwards.

Ich habe Verteilerlisten angelegt, Eine davon hat fast 200 Empfänger, die alle nicht öffentlich erscheinen sollen, also im BCC liegen. Das Versenden der Rundmails an diese Liste funktioniert praktisch genau so unkompliziert, wie das "normaler" Mails. Toll!

У этого расширения есть поддержка русского языка ?
И можно ли при рассылке задавать интервал времени для отправки писем ?

Even accepts variables in the href attribute of links!
With a "send later" option, the addon could be perfect. A must-have for a quite small list and maybe more!

I really appreciate this module, and I use it intensively for mailing to students and colleagues. My typical mailing size is 20, driven by a rather complex CSV configuration file with a dozen of columns. It works perfectly.

I have a suggestion: adding a mean to exclude certain lines of the CSV file to be included in the processing. It could be for instance is some variable is defined. This would enable partial mailing much more easily than today.

Really handy extension for Thunderbird. Would like an option to reuse a template already designed with the various fields etc without the extension creating a copy of the same template during the mailmerge.

This is particular an issue when you have multiple people doing the processing.
