I've been using Mail Merge for quite a few years. It took some learning at the beginning, but I use it effortlessly and well now. My experience is all with CSV file as source, and "send now" without any other options, and the program works flawlessly. Love it. Couldn't live without it. Alex, why don't you have a "donate" button? Unless you're filthy rich, I'd like to improve your life a little as thanks for improving and simplifying mine!

Great add-on, and thanks for showing me what I did wrong.

(I have updated my review in light of Alexander's clarification of an issue I had with conditional statements, and to help others avoid the mistake I made.)

In case anyone else has an issue with conditional statements not working as intended, you may have a syntax issue. Taking one of the If/Then/Else constructs as an example, say '{{var|$|if|then|else}}', let me explain;

Af first glance, you may think, as I did, that in order to make that statement work, you would simply substitute the parameters with your variables. Thus, you might write something like the following:

{{{{JobTitle}}|$|{{TestField}}|{{ThenField}}|{{ElseField}}}}

However, this is incorrect!! The right way to implement this would be to use (notice the lack of curly brackets around JobTitle):

{{JobTitle|$|{{TestField}}|{{ThenField}}|{{ElseField}}}}

The conditional syntax is actually an extension of how variables are represented, rather than a separate construct. So, to use the job title field in your email without conditions you would refer to it simply as {{JobTitle}}.

Note that you can use string literals, variables, or combinations of these, as the 'if', 'then', and 'else' parameters. It may also be possible to perform indirection on 'var' if you construct 'var' from variables and text, but I haven't tried this.

I needed to send a simple e-mail to 50+ members to confirm their contact info. (Nothing fancy, no logic conditionals) The MailMerge extension worked perfectly once I conformed my source .csv file to the exact variable names supported by Thunderbird (no spaces, capitalization the same) , and the sequence it expects (i.e. followed the developer's instructions).

Please, add to the description. When using on Windows with .CSV, then, after saving the .CSV, it's better to reopen it in a text editor and save it in UTF-8, and after that choose UTF-8 in the add-on's dialog window. Otherwise there may be some charset problems or even errors in sending emails.

Excellent add-on for sending customized emails to many people at once. However it would be great if it would allow nested variables. For example,

Pluralizing numbers:
{{NumProducts|==|1|1 product|{{NumProducts}} products}}, which would use the text "1 product" if "NumProducts" is 1, or else it would display "{{NumProducts}} products" if it is not 1.

Either one variable or another variable:
{{Name||{{Company}}|{{Name}}}} which would use the text of "Company" if "Name" is empty, or else use the text of "Name"

URL containing string:
{{PromoCode|||Click on http://www.example.com/promo/{{PromoCode}} for a {{PromoDiscount}}% discount off your next purchase}} which would add this text if the "PromoCode" is not empty.

This is really good - and could be even better:

(Alexander, you seem to be German, so I'll be lazy):

Scheinbar hat Thunderbird die eigenen Maßnahmen zur Überprüfung der EMails auf Gültigkeit verbessert. Zumindest bekomme ich heutzutage reichlich Fehlermeldungen noch bevor die Email rausgegangen ist.

Mail Merge wird durch diese Meldung im Sendeprozess unterbrochen, wenn man es nicht gleich merkt wird mitunter auch der ganze Sendeprozess abgebrochen. Das ist sehr lästig. Die Lösung wäre ein Überspringen und Ausgabe eines Sende/Fehlerprotokolles. Vorschlag: Ausgabe als CSV-Datei, die dann direkt überarbeitet werden kann (Tippfehler korrigieren, zum nochmal probieren, oder einfach aufheben als Dokumentation).

PS.: Die Bewertung "Excellent mais" hat das Gleiche zum THema.

Je suis novice et j'ai expédié un message à partir d'une liste de +- 20 noms en utilisant .csv.
Mais si une adresse est erronée (courriel) alors tout le processus semble stoppé. Je n'ai pas encore trouvé le moyen de ne pas recommencé tout le processus autrement qu'en refaisant une nouvelle liste (.csv)

I've used this program for years. It's quite feature-filled and useful.

I use this sparingly, not every day. So sometimes I forget which settings work and which do not. This has led to two high-stress problems for me recently.

First, I always forget how to get attachments to work, and I struggle to format the .csv file correctly. The best luck I've had is to make sure that a double-quote is around every text field in the csv file. But I've had trouble getting even this to work before.

The second problem sent me in a panic earlier today. To my memory, I thought that the default send setting on mail merge was to save everything as a draft that I can review before sending. I realize there's an option to select this, but I thought it was the default, and I ended up sending a bunch of letters I didn't review. This turned out to have fairly bad consequences in this case, actually, and in any event was an unpleasant surprise.

These are really my problems, and shouldn't reflect poorly on the program. But it could be improved by making it more idiot proof: making "save as draft" the default setting and having a simpler way to associate file paths with other data for attachments.

...you can be certain the product has earned it.
MailMerge is a deceptive add-on because it's simplicity to use masks a very feature rich functionality that I have only begun to explore. I have a couple of clients who are going to be even more delighted by MailMerge than I am, if that's possible.

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.
