There's not much that you would want to do in this situation. The system is working as designed. You should change your password to something you don't use elsewhere just to be sure they aren't attempting to log in with your actual password. 4 emails in 10 days is not excessive. If the e-mails bother you and your account is secure, then you can just filter them into a folder and then go looking for them when you actually need to reset your password.
