If you contact support from your account, the support reply may probably go to the email address you don't remember.
Log out of the Spotify website in your browser and fill out this contact form. Someone from Spotify will be happy to help you get access to your account again.
Make sure you are logged out of any Spotify account in your browser when using the contact form or the username and custom email field will not show up. It is important so that you can enter the information of the account you are having trouble with. If you are logged in with a different account that is not having the problem, that account info will be used and support will be confused.
You should get a reply within 24 hours. Don't forget to check your spam folder for responses as they may end up there.
If you get an automated reply email telling you to check the help section or the Community, you need to reply directly to email@example.com
Alternatively, if you prefer support via Twitter, you can tweet @SpotifyCares.
