The problem with several of these email subscriptions is that they will reissue your email address to another if you leave them, with all the risks that entails. The answer is to buy and use your own domain or get someone else to do it.
This is a good idea but in practice it just shifts the problem onto the domain registrar. Maybe/hopefully they are friendlier than email provider but if you do Gmail vs Google Domains, what's the difference?

Google Domains has (at least in theory) the option to transfer the domain to another registrar. Gmail does not let you transfer the email to annother mail provider (because that would be impossible).
That only states that you currently can't get past names using the normal signup pocess. It makes no promises about the future and does not guarantee that there is no separate VIP signup process that has fewer restrictions.
