This would be useful for lists of emails with no first or last name associated with them.

For example, I have a lot of emails in Mailchimp with no name--simply the email!

Instead of trying to add each individual email as a constituent with an "N/A" last name, it would be nice to have a spot to import just the email for ebalsts out of the NXT email module.

Alternatively, It would be nice to have the "LastName" field be a business rule rather than a Blackbaud rule. Sometimes we just have the email and nothing else.
