Can anyone with experience compare Mailtrain / Mautic / others? I did a quick Mautic setup on a DO droplet a while back. It felt a little like beta software, a lot of careful steps to get things working, some things didn't work, updates and some actions on a clean install gave me PHP errors, Amazon SES API wasn't built yet so sent super slow via SMTP only, etc. And it leaned way harder into marketing automation as I should've expected from the name (JS on page to track users then associate them if/when they sign up later). This was at least a year ago and they've had a major release since so might have fixed some of these but I'm still trying to save money for a small business who can't afford $200/mo for sporadic newsletters and welcome series with free stuff.
