I already use Tuta as my email provider. I already have a domain I can use with it (bought privately). What privacy implemcations does it come with.
The main reason is because I would like to be able to keep the same email address for longer and not have to change when/if I change providers.
Your own domain is not great for privacy though like others have said the registrar can hide your info at least from whois. If you already have a domain lookup the whois record and see what it says. Presumably even with whois privacy your identity is probably discoverable.
Custom domains are not great for deliverability too. Though mostly mine is fine. Sometimes Yahoo and ATT manged accounts give me delivery issues.
What your own domain is good for is nice, long term, and portable addresses. Also for many cheap addresses. I get something like 30 email accounts with my basic Namecheap cPanel account for about $25 per year.
Instead of 30 addresses it’s generally easier to just enable catch-all on your primary address. That way you’re not manually creating each new address.
Mine was fine until I upgraded my broadband. Under my new service the ISP doesn’t allow their IPs to be taken off of the Zen spamlist, so I’m pretty much fucked over and at the behest of the ISP
Edit: How do you have a limit? You outsource? I self host so my limit is my hardware.
Edit 2: Ah I see, there are services that charge for their hardware.
Do you mean 30 email accounts for $25 a year?
Yes. I do not use them all, but I can and my cPanel shared hosting only costs $25 per year. I can use web hosting part too if I want. It is all included. The above cost does not include the domain name itself.

Edit: Looks like after first year it will be about $50/year.
