If the email address entered here is the same as the email in your public listing, it will, of course, be seen.
If the email address here is different, it will NOT be seen by the public. It will not be disclosed to any other party.
For automated approval, the domain of the email address must match either the domain of the email in the public listing or the domain of the agency's web site.
Example: In firstname.lastname@example.org, "myagency.com" is the domain. If the email address in the listing is email@example.com or if the agency's web address is myagency.com, approval of your registration will be automated. Otherwise, verification of your registration will be done manually.
