I needed a mailing system for my joomla page, compared some extension and decided on Mailster. Never regretted it! Started using the basic version last year but then switched to the professional version some time ago. Very good decision, only had one problem so far, concerning the double-opt in feature but i got help today after waiting for less then a day, despite asking the question on a weekend!
The extension itself is easy to set up and offers a lot of features.

I run a website for a small sailing club. We have several mailing lists for members, committee etc., which used to be managed in a Google Groups account. After installing Mailster, I was able to greatly simplify the management of these lists as they are now all administered from within the Joomla backend. I've had a couple of small problems which have been sorted extremely quickly by the developer, Holger. I've just upgraded to the Pro version, which has made the mail archive available on the frontend of the website for all the members registered at the site.
This is a great extension, which I highly recommend.

I have been using this software for many months. This is absolutely the best email discussion group component for Joomla!. Its easy to use, easy to setup, a huge amount of optional features and tweakability, and best of all...RELIABLE. It is also the only software I have found that ties Joomla ACL groups to mailing lists, which is SUPER handy. I don't know what I would do without it.

I installed Mailster v0.40 on a Joomla 3 install and had a niggling problem with the plugin version when trying to assign it to an article. I emailed Holger at their support address and I have to say I was VERY impressed with how much help he gave me to get over the issue. Thank you Holger, great service and a great addon for Joomla!

I started with the free version, but was impressed by the product so I purchased the professional version. A problem reported when using Joomla 3.2 was resolved with an update within 24 hours! Excellent service!

Mailster is an excellent choice for people who want to manage their mailing lists based on Joomla users. There are a lot of options and the component is working very smooth. I would recommend everybody to buy the Pro version, as you get a lot for your money. In case of any problems, the support is very fast and takes time to solve your issues.

I have been using Mailster for over 2 years and found it to be an excellent component. I’ve recently upgraded to the pro version, and wish I’d done it sooner, the additional functionality is well worth it. The component feels so mature I don’t understand why they haven’t made it a full 1.0 release yet. Don’t let the fact they are calling it version 0.4.0 deter you from trying it, it is more mature and stabile than some products that are at version “2.0 +”.

I had an issue with one of my clients, it was taking a considerable amount of time to get all the emails sent to their full recipient list. A couple of email responses from Holger later (same day) and I had the full process down to under 10 seconds. Was purely poor configuration choices on the client’s part, component worked perfectly.

In summary:
1) If you need a simple yet powerful mailing list component integrated into Joomla’s/Community Builder’s user lists this is it.
2) Support is excellent

Mailster is, to me, a critical component of the Joomlaverse in its ability to tightly integrate email, and particularly an internal mailing list, with a Joomla website. My client had used a Mailman mailing list for years for 130 lawyers and was reasonably happy with it, but it was completely separate from their website. They were two ships passing in the night. The user lists didn’t correspond, and a lot of very good information was shared on Mailman that didn’t make it to their website. That’s a critical loss for a group that is trying to build a searchable database of information that grows in value over time.
Mailster changes all that. It duplicates the capability of Mailman as a closed listserve and adds many more very useful (and kind of amazing) features:
1. It integrates tightly with Community Builder, so you only have one database of users. You no longer need to do painful user reconciliations between the group’s website and its listserve/mailing list.
2. You can add users, permanently or temporarily, to a mailing list who may not possess registered access to the website.
3. You can create as many mailing lists as you want, all from the same interface. This is useful in my client’s case for subgroups of lawyers who might be collaborating on a project.
4. The archives are immediately available on the front and back ends, and are searchable both with a Mailster search and a Joomla full-site search. Attachments appear in the archives (unlike Mailman, which drops them), and they are likewise searchable. This is huge. It means that all the information the group shares is available on the website and easily found either by search or using the menu items for the mailing list front-end archives. A list view and threaded view are both available.
5. Archives for multiple mailing lists can all be set up to be viewed on the website, each with their own menu item or all combined. Using Mailster’s user group tools and Joomla ACL, you can restrict archives to a subgroup of users.
6. Even a complete Mailman archive (but even better, including attachments) can be integrated on a website using Mailster. If you want to keep a Mailman list active, you can set up a public mailing list (perhaps with a complex, non-guessable email address) in Mailster with just one recipient, and list the complex address of that mailing list as a user on the Mailman list. That way, Mailman will send its emails to Mailster, which will incorporate the archive on your website (including attachments). The archive can be viewable by registered users only if you choose. (Note: Mailster is not a "Plugin" solution for Mailman, and imports no existing data from Mailman.)
7. There are lots of possibilities beyond even that. Many of us have clients that are terrified of adding something to a website. But they’re not terrified of email. You could set up mailing lists in Mailster by functional category and give each of them a separate email address. Users who email something to that address will find the contents of that email in the website archives for that category’s email address. This is not the same as Joomla categories … you can’t email an article to a category. But functionally, it gets pretty close to being able to do just that.
I think of Mailster as a flexible bridge between (1) the email interface that everyone is used to and (2) your website, a group’s listserve, specialized mailing lists, and the searchable content of the website itself. It’s a wonderful tool.
One other note: Holger, the primary developer, is extremely knowledgeable, professional and responsive. If you need clear and fast help, you’ll get it. But get Mailster Pro … it’s worth it and necessary to do much of the above!

Best service, excellent product
I was able to install this fairly quickly and got it up and running with the helpful manual that came with this. Ran perfectly the first time out and I even had a rapid response from the developers when I needed to extend the use of the product to interact with Community Builder - using multi-check boxes to create mailing groups. All my requests were handled quickly and to my full satisfaction. Excellent service and excellent product!

We are using Mailster for mailing within a small club. It allows for mailing lists that are extremely simple to use.

The extension works exactly as described.

The developers are active and extremely helpful in case of issues.

I have been using Mailster for about six months now. I found it to be a very user friendly setup in Joomla.

However, whenever I did have a question, their support has always been 100% friendly and supportive.

I highly recommend this extension!!! ♥

Our Joomla! Installation had problems with the Mailster installation in operation. Brief contact via e-mail and voila, fast and competent assistance by Mr. Brandt.


Thank you.

We wanted to avoid the double handling of managing mail lists in our cPanel hosting software separately from our Joomla site. Mailster works a charm, was easy to configure and just what we needed!!

A great extension for Joomla, setting up the mail settings was a bit fiddly but the self checking option on each tab was really useful.

One thing which puzzles me, the time shown is very odd, not corresponding to any time scheme I know of. The date is right. However the option to take the time out of the email is a help.
Owner's reply

Thank you for your excellent review!
You do have the option to format the date/time format as you like - there is an option for that in the component's configuration.

A great extension which will make my life a lot easier, allowing other people in charge to send out their newsletters. Their support is even greater, had a small problem with the header and footer pictures not showing in the email send. A very quick response from one of their developers solved the issue (not related to their extension btw), very impressed. Most paid extension don't deliver support like that.

I was looking for a Joomla newsletter extention which could be operated by front-end or email, as it needed to be used by luddites. This fits the bill very well, as the content can be provided by email, and subscription can be handled by recipients as well as in the back-end.
Installation was fairly easy, although I found the server options a bit over-complicated, and it worked first time. It took a while to find all the appropriate settings, but the process was fairly painless.
I can see one major problem--the lack of full integration with the Joomla user list. Subscription seems to default to the user's registered email, but this can be changed at subscription time. If the user subsequently changes email address, this does not update Mailster's address, and they get out of sync. Finally, removing a user does not remove it from the mailing list.
Otherwise, this is a very good extension, and I would recommend it for simplicity of operation.

Thank you for your review!

This extension is easy to install and use. If your site is not frequently visited but you want the mailing lists to work after all, then pay attention to the help on how to create automated visits to your site and keep the framework awake.
One thing drove me crazy for a few hours: if you manage a site through httpS and Chrome, be sure to allow Insecure Content to be loaded, otherwise many functions misbehave.

My web-host is great, but their mailing list software sucks (sending commands via email?!). So I'm very glad this extension for Joomla exists. It turns a Joomla installation in a full featured mailing list server. There are tons of options and the interface makes it very easy to configure and maintain. Update cycle isn't the fastest, but I'm not looking for tons of new features anyway. Reliability is important. If the next Joomla version should make Mailster incompatible, I'm certain an updated version will be available in no time. I've been using Mailster Pro for like 8 months and it sent about 600 emails to mailing lists (5 up to 40 recipients). Maintenance effort on my part? Negligible. E-Mail Support is good, no complaints here. The Pro version is bit pricey, but it's well worth the money.

I was looking for a replacement for dadamail in a Joomla environment about 6 months ago. I found Mailster and I couldn't be happier. The extension is easy to use and fits my needs perfectly. The pro version is well worth it for me. I have had very few problems, but when I have, Holger provides lightning fast answers to my questions and I'm up and running again in no time.
