If you can't see any exchanges from your email then try this one below as an alternative from jrrsparkles posted above

Sort them to the oldest one to find the exchanges that still exist at that time. After that try to log in to any exchanges before 2014 if you can't remember the password just try to use the forgot button and put the email that you used before. Let's hope that you can find the right exchange after you receive the recovery password.
