How effective is changing email addresses to alias?

do websites still have a history of old email addresses you used to use? Is it better to recreate accounts with the new email rather than just switching it?

I would assume they keep your old email. When I started with Proton and aliases, I created new accounts (where possible), and deleted the old ones.

I feel like this doesn’t exist, but is there a phone number alias service similar to simplelogin?

https://relay.firefox.com/. Firefox has a new phone relay service. It’s so new, I don’t have any information on it.
