Welcome to the brand new list of Target Marketing's Top 50 Mailers. For the first time, we are relying exclusively on data from our partner Who's Mailing What! in compiling this list, as well as the other lists in this article, combined with list management information provided by SRDS. Who's Mailing What! has compiled the most complete library of direct mail and email in the world, and has tracked mail for more than 25 years. Earlier this year, it relaunched on a state-of-the-art, fully searchable platform.
