This is a page to test emails (August 1, 2023)

Rules:

1. In most cases, the columns users.user_login and users.user_email should be the same unique, valid e-mail.
2. The user profile creation should create a psp_primary_email row in user_meta and fill it with the users.user_email value and set the psp_preferred_email to “primary_email”.
3. If a user specifies and chooses an alternate e-mail, a row should be created in the user_meta table with psp_alternate_mail and set the psp_preferred_email column to “alternate_email”.
4. The user may toggle between primary and alternate emails, the column psp_preferred_email should always contain the correct value of either “primary_email” or “alternate_email”.
