Getting newsletters to gmail?

My account settings show my yahoo address - only.  Yet I am recently getting newsletters to my Gmail address.  I do not want any of the newsletters.  To my knowledge, my Gmail address is not on record.  Unsubscribe does not negate the newsletters.  How do I unsubscribe for a non-listed Gmail address without simply banning all email from SA?
