I picked zoho.com free tier, with an eu.org domain after scanning through a set of different options. No marketing appended to emails and only throttles on excessive sending instead of hard limits. Each service sends from its own address.

purelymail.com was my backup paid option if the free plans were no good, with the advanced pricing and low usage the cost would be miniscule.

You might consider something like the friendly elec CM3588 for a DIY option with openmediavault or freenas. I have a big old box currently with spinning metal, but am looking at this as an option now that there are some larger m.2 drives available.

I tried bazzite, which is very close to kinoite, as Fedora itself had a great out of box experience, even on laptops.

Whilst there was a way to get most setups, apps and configs working it was clear I would eventually run into a piece of software that the effort to get it working was not worth it. Some software and development tools are not (yet) designed and maintained to easily work in an immutable environment.

My biggest gripe was that any interaction with os-tree meant that updates now started to take a really long time building the image with high CPU/power usage. I wasn’t ditching Windows to go back to a world of unnecessarily long updates.

For some, I can see the immutable can work well if they want an Android like experience and can accept the software catalog available. It wasn’t the right model for me, as I expected my machine to do more than point and click app install. I would be curious how your typical arch user would find it.
