Hi, Im thinking about moving from gmail elsewhere but Im wondering if I should use my own domain for it, I dont have the domain yet but how to deal with whois lookup privacy? (Im EU based) are there any other issues I may run into if I chose my own domain over opening a account on posteo.de or mailbox.org with their domain. I know owning my domain will give me freedom to move my email elsewhere if I would want but I dont know if its worth it.
Any decent domain registrar provides WHOIS privacy for free (just note that that might not be available for .eu domain names). Additionally you can always use fake data on your account, but in this case you might lose your domain if they decide to check it.
When registering a domain, always look at the renewal price: often the first year costs relatively low, but after that there’s a steep price increase.
As for an email hosting service, in addition to the ones you specified in your post, I suggest you to look at migadu.com.
