Hi - generally, I'm a big fan of SubsiMail. I have it self hosted and its really been a wonderful and helpful alternative to something larger like Woodpecker. I am a small business owner and it is allowing me to do some good work.
There are two big issues though that I really hope you fix, as they present what feels like frequent disruptions.
First, disabling old versions. I am using the TrueNAS community edition of the app and versions are often discontinued before they are updated in the TrueNAS community store. I have campaigns already set up, so moving to a custom YAML would be a headache. It would be extremely helpful if you could have some sort of 30 day buffer for old versions or at least wait until the TrueNAS community version.
Second, your licensing heartbeat server (and seemingly website) have gone down twice in a month and when the license can't verify with the server, SubsiMail shuts down. Again, this is a place where a 30 day buffer would be most helpful.
The pace at which you're providing updates is genuinely appreciated but these updates are causing me, presumably others, to lose precious time on their work. You've built something impactful but the disruptions are a bummer.
Thanks for considering
