We’ve put in the inquiries with the United States Postal Service on this, but until we receive comment, we’re hearing from sources in the know that some of the agencies pitching for the USPS creative business include WPP siblings JWT and Grey. We’ve been told that both are finalists while other names that have been thrown in the hat include Mullen and Droga5, though the latter two have yet to confirm involvement (Update: We’ve been told by sources that Mullen is NOT in the mix, though the first two we’ve mentioned are).

It’s been six months since the government agency began cutting ties with Campbell-Ewald, which had been working with USPS for 10 years. The Postal Service shifted its media duties, meanwhile, to UM. Sources add that a decision is expected to be made by the USPS in April.
