I have seen around on the Mautic e-mail/campaign builder. There is some nice features with the dynamic content, but I can also see that the builder is very old school compared to other companies. But of course it is also free of charge, so no complaints.
At my former work it took a backend developher around 20 days to build the most coolest e-mail builder I have ever seen. So I am thinking, out of so many people who is using Mautic, did anyone rebuild on the e-mail builder to be more functional etc? And again no complaints, just a question.
