A couple of things I noticed...

 Code:
$recordset = DBGetRecordset("$objConn, $SQLQueryRS")

The arguments you pass to DBGetRecordset shouldn't be in quotes. Just:

 Code:
$recordset = DBGetRecordset($objConn,$SQLQueryRS)

...is sufficient.

On a SQL note, if you want to ingore duplicate email addresses, just add DISTINCT into your SELECT clause:

 Code:
"SELECT DISTINCT 'Email Address' FROM 'Person'"
