Well WebDav/CalDav/CardDav works quite OK. Baïkal is trivial to selfhost (cal+card) then you just pick some webdav implementation like KaraDav/PicoDav/FlyDav and you are good.

Email is really the one that requires lot of caring about so not easy to self host.

IMHO the problem starts when you need to share your calendar with the outside, then you need to expose that service to the Internet and, to me, it's a whole different level of complexity making sure it remains safe.

If read only is good enough, a simple export of the .ics to a bucket can suffice.

Yes I'm aware, what I'm saying is, in the time between setting up my home server again, I've realised it's not even that useful. I used to think that having my todo and calendar locally on my phone was unusable.

You can self host email in an afternoon, its not nearly as bad as people make it out to be.

It's not about configuration but rather your IP reputation and the struggle to not have your mail go straight to addressee's spam folder.

Thats just a matter of buying a decent IP and setting up DMARC and DKIM.

I see this reasoning as the #1 reason not to self host, but it really isn't a big issue once you do the initial setup.

Please expand on this. Public cloud IPs would be on spam lists, and providers like Hetzner and OVH aren’t any better. Where does one go to buy a decent IP?

[throw-12-16]

Use an IP reputation tool like https://mxtoolbox.com/blacklists.aspx

What you will find is that many dedicated IP's from larger vendors are fine.

I personally use Hetzner and don't have any issues with reputation at all.

[kassner]

I had troubles with Apple blocking a bunch of range IPs from OVH, because they don’t handle abuse claims. It didn’t show up in blocklists at the time, but was in practice unusable.

IME anything that can be purchased by an average developer is in some list nowadays and deliverability is always crap (with luck it lands on spam folder).
