Are you referring to our weekly newsletter? If so, unfortunately our email provider only allows one unique email address. To resolve this I would recommend using a second email address, or otherwise use GMail's + operator, which allows you to have multiple email addresses under one account (e.g. email@example.com and firstname.lastname@example.org). There is no other way to resolve this issue at this time.
If you're referring to something else entirely, please explain a bit further.
