Useful selections. I'd also like to add this directory (OpenAlternative), which suggests open-source alternatives with filters & sort options.

Hi @kwnaidoo thanks for the feedback on Mautic, I was trying to consider introducing it in our company, and I found your comment here I would gladly be happy to have your guidance on the performance issues you mentioned, In our company we are targeting around 500k SMS per day.

Yes, we're doing a lot of work refactoring core ourselves when it comes to the performance issues with Mautic. 5.1 has a lot of improvements and we've got a backlog of PRs relating to scalability.

Perhaps you could help us with testing some time given your expertise, docs are at mau.tc/tester and we'd always welcome contributions from the changes you made to your own instance if you feel so inclined!

I would say, however, that my experiences with Joomla have been really quite positive with the 5.x series - the UX is much more friendly, there's a bunch of nice built-in accessibility features and overall after being a long term user I feel like it's the best release edition yet (using Joomla since the 1.x days).
