That's what I usually do. I have a first initial + last name @ gmail.com account and tons of people sign up for accounts using my email address. Unfortunately, doing a password reset on for a bank account, cellular account, or the like is usually impossible without an account number or something else. As it should be, but it's really important that people use closed-loop sign-ins and allow people to remove their email addresses from accounts without logging in.
