Email itself cannot be regarded as a reliable delivery method. That said, I host my own email service, have for decades, and often have problems sending to people. I am not running a product on it, and so my recipients usually will check in spam since they want my email. My family knows to txt if there is an email I need to read (that isn’t a mail hosting problem but I don’t really read email consistently). I also have a small web site where I can put family recipes and my resume and the odd file that is too large for email. And a mastodon instance, sync thing, dns, and an old fingerd I wrote in Lisp in 2008 when I was done being a stay at home dad and needed an industry job.

It is a great hobby, and a good way to keep aware of current trends in internet infrastructure. And, like riding a bicycle to commute, maximally free of red tape or external regulation.
