What about a CASE statement to insert a constant into the name fields if they are blank? Then, you can use a distinct to ensure you return only one email address for null names?
SOmething like: Select DISTINCT CASE WHEN FirstName is null THEN 1 ELSE table.firstName END AS FirstName, CASE WHEN LastName is null THEN 2 ELSE table.LastName END AS LastName, emailAddress Every record with a null first and last name should look the same, unless their email addy is different. Think that'll work. Syntax untested of course.
