I am part of a small non-profit online workshop organization. We have a small hetzner server to host our email server. I don't think we ever had any trouble with email delivery in the year we have run it. I also set my personal email server (mailinabox on the cheapest hetzner server) last month. All my emails were accepted. Only some exchange emails to my friends were initially sent to spam, but after asking them to mark the emails as not spam, and them replying to me a few times, I have not had further delivery issues. I did have some weird kurfufle with dns last week, where my domain would not resolve. There was some notice on the namecheap website about some dns outage, but it has disappeared since then and I was too busy to explore then. I just spent yesterday resetting everything in namecheap configuration after which everything started working again.
