How do I unlink an email from my account?
Edited
If you no longer want to see data sharing agreements for an email, you can unlink it. You'll just need to ensure it's not the primary email for your account.
Unlink a social profile or email
In the menu, click Settings then Linked Accounts.
Find the account you want to unlink and click the More actions menu.
Click Unlink account.
Your account will be unlinked. You won't be able to sign in using it and you don't see any more data sharing agreements related to that email.
