What's the point of the email address in the query? Since you have a users userid, in the $id variable, that will uniquely identify everything you need to update the appropriate stuff in the subscriptionthread table.

If what I understand you want to achieve why not use the following query:

PHP Code:

 $db->query("UPDATE " .TABLE_PREFIX. "subscribethread
                   SET emailupdate = 0
                   WHERE emailupdate IN (1,2,3)
                   AND userid = $id"); 


Also note two things, first your $db->query should use () not {} and have a ; at the end, and also an update query can only be applied to a table and not a join.
