I use one dedicated email address per service.
This is a golden rule I started about 20 years ago. Today I have about 700 email addresses in use. The Password Manager keeps track, which Email address is used for which service.
This has several advantages:
- An attacker has no idea which email address I use for a certain service: this makes attacking my accounts a lot more painful
- I can very easily sort incoming email associated with those services
- It becomes more difficult to track me
Lately more and more services do no longer allow me to create an account with an email address I designate.
Instead authentication is delegated to a third party (e.g. Discord, Paypal) and the email address associated with that service is used.
Such a service will never receive any money from me.
