Regarding email, consider buying a personal domain for your email address. You specify the ip addresses of the email provider in the domain’s DNS, and on the provider’s side specify that the domain is for your email box. This way, if the email provider doesn’t work out, you only need to change the DNS records to another provider, instead of changing the email address on accounts (which is often impossible).
However, not all email providers support custom domains, and some only do that on paid tiers.
