I guess if someone is a better sysadmin than me and knows how to deal with recipient servers auto-marking emails containing sexy language as spam, independent hosting could still work? I've been paying ยฃ30/month for newsletter hosting and would happily continue doing so. But I spent a few months trying to send to my (entirely opt-in) mailing list from my own server, and I couldn't find a way to stop my domain getting marked as a spam sender by the big email hosts ๐คท
