A big step forward

We are very happy to announce the release of Mailster 1.0. Although the release version 1.0 might indicate it is a complete new product everyone familiar with Mailster knows it has been in development since 2010 and that there were more than 15 public releases since the first release named 0.1.0.

Mailster 1.0 is the result of further development on the existing product bringing in many long-awaited features, improvements and bug fixes.

New Product Editions / Mailster Professional discontinued

With reaching this milestone we decided to discontinue Mailster Professional and introduce three new product editions in addition to the existing basic version of Mailster which remains free, of course. This are the four Mailster flavors we offer from now on:

The goal of the new product editions is to provide a cheaper entry price for a more advanced version allowing more recipients than the free edition. Many of our customers are non profits and will benefit from that using the cheapest paid option Mailster Essential. For more advanced use cases we offer Mailster Business and Mailster Ultimate.

You can find information on the differences between the product editions in our pricing overview and a list comparing all of the features.

Professional subsribers get access to Mailster Business

All customers that have an active Mailster Professional subscription were migrated to a membership plan of Mailster Business for the remaing time of their subscription period. This enables them to benefit from the many improvements of the new release while making sure they keep the functionality of the former Professional product edition as all (and more) features are included in Mailster Business.


Feature Highlights

Joomla groups, finally!

You are now able to choose from your Joomla user groups (e.g. "Registered", "Administrator" or any of your custom defined groups) to use them to manage your mailing list subscribers on a group level and also for the list's rights management (e.g. who is allowed to send to list?).

Simply go in Mailster to User Groups >> [ + ] --> "Method 2: Use Joomla group" and choose the groups you want to use for managing recipients and so on. Then, this Joomla groups can be used just the same as the groups of Mailster.

Improved Compatibility

We made sure Mailster still runs on Joomla 1.5, although the 1.5-support will probably dropped early next year. Therefore an upgrade to Joomla 2.5 or 3.3 is recommended. Speaking of: this release runs on Joomla 1.5, Joomla 3.1, 3.2 and 3.3. We have only dropped the support for Joomla 1.6 and 1.7 as these release are outdated and insecure.

Email Digest Mode (Mailster Business and Ultimate)

Subscribers can now decide to receive the mailing list messages as daily, weekly or monthly digests.

The admin can edit the digest settings of the subscribers and also enable/disable the digest feature on a mailing list wide level.
