Most probably some of the $RecSet->AddNew(...) failed. Does the method return some kind of success/failure status? And aren't you supposed to call something like $RecSet->Update() or something if you use this insane way of adding data?

Basicaly you'd better forget about ADO, change the script to use DBI and DBD::ODBC and use the normal way of adding data:

use DBI;
$db = DBI->connect("dbi:ODBC:$DSN");
$insert = $db->prepare('INSERT INTO Addresses ("Email Address", "Websi
+te Title") VALUES (?, ?)')
 or die "The INSERT statement is wrong: ".$db->errstr()."\n";

while (...) { 
 ...
 $insert->execute($email, $titlePage)
  or die "Failed to insert the email $email : ".$db->errstr."\n";
}
