Proton will so smtp if you’re on one of the paying plans. You can get your own domain setup to use with it. This is what I do. I just had to contact them to get it setup, they ask a few questions about usage, which I just said was self hosting stuff and sending occasional emails.
Just as long as I can get a full refund if I’m unable to attend anymore. Maybe up to an hour before or something.
For my use case, I can’t get it to autoplay the next podcast. I would need to setup a playlist or something. The Web version does this just fine, just not the app. I’ve been playing with Absorb and that seems to do this, though in Android Auto mode it breaks occasionally. Can’t speak for this app. Maybe I’ll try it and see.
In the most literal sense.
Maybe some day, don’t break what isn’t broken (for now).
