I beging with the premise to reduce email to zero so that every interaction I make with it to make it more secure, simplifies it and removes it from a method previously used, if possible. I use a different email for each service that is financially related, that I cannot "not" use email and whether by alias, or not, each hackable service is then reduced to one email with no knowledge of my other ones, by domain too. Obviously, different passwords (where then that becomes the honeypot, both in knowing your other emails and passwords to them). Simple. As for easy account logins through a service reusing the same account, those are restricted to non-essential, go ahead, take it, I don't care type of scenario. Some of those accounts may have a payment system attached to it which I don't leave on the system, but enter manually, or the access to it, has very little money that it could steal.
It comes down to more inconvenience to you what you value more going to most convenient to what you value less. With each interaction you make with them or new, to make a change, you evaluate. In this way, you spend less energy managing it 🙂
