I don’t often take the time to write a review but the “support” for this plugin 
is absolutely abysmal. The last FOUR WEEKS of trying to switch from legacy Mailster
to new forms has been excruciating. It’s been a complete waste of my time as a developer
and a complete waste of my client’s budget, having me liase all this time only to
have to give up because ‘support’ won’t help. Firstly the ‘legacy’ forms were hacked
and they were being used to send spam, so the hosting company took the website offline
until the issue was sorted. I completely removed the legacy form, got the website
back online, and then tried to switch to their new forms….. and then the fun really
started! Their documentation is awful. It’s not even basic. So I kept having to 
reach out to ask one excruciating question after the next, one question a day, one
answer a day. The days and weeks dragged by and we still can’t create a ‘Mailster
Homepage’ which is the new feature that replaced the ‘legacy’ feature. This newsletter
was used on a large health organisation website which is funded by the EU. Of course
we’re not going to grant 3rd party access to a live website so that can start testing.
ONE MONTH LATER and the issues are still not resolved, because ‘support’ have said
that they won’t help. The reason? We don’t have a license for the staging/development
site which they can use to troubleshoot the issue. We have now moved to a popular
3rd party solution because this last issue was really just the last straw. When 
the plugin was still working it would take an entire TWO DAYS just to send ONE newsletter
to a small list of 2400 subscribers, even after using their ‘intelligent email throttling”
or whatever fancy name they give for a tool that makes no difference at all. We’re
not on cheap hosting either. We have dedicated CPU and processors. Don’t waste your
time with this plugin.

 [Patryk](https://profiles.wordpress.org/patryktarachon/) 2025年11月3日

I’ve been using the plugin for 2 years, it works averagely. Since then they’ve only
introduced up to 3 automations, which rarely work. It still doesn’t load blocks 
and constantly displays error messages. The worst-optimized newsletter plugin. Considering
autoresponders, I’ve tried many times to figure out why some work (despite the same
settings) while others don’t send. I also don’t understand why some subscribers 
receive Auto-responder messages while others don’t, despite being added to the same
lists. The time since they registered doesn’t differ from the time those who receive
these messages. The plugin requires a lot of patience from developers, not to mention
non-technical users.

 [emma336](https://profiles.wordpress.org/emma336/) 2023年6月28日

What a nightmare of a plugin. There are virtually no instructions on how to set 
it up, it’s unreliable and has lots of bugs. We had an issue with it trying to send
hundreds of emails without knowing why it was doing it and there’s no way of knowing
how to solve the issues.
