I didn’t receive an email after logging in

This can be caused by one or both of the following:

1. You did not opt in to marketing communications during the login process.
2. If you logged in with email, you did not click the verification link in the email that we sent you.

Regarding point 2, we will only send emails to verified accounts. You could log in using potus@whitehouse.gov but while it is possibly a genuine email address, it probably doesn’t belong to you.
