Entries for the DMA Door Drop Awards will be accepted starting from October 10, but the shortlisted entrants will have to wait until February next year to find out if they've won.
According to the Direct Marketing Association, the judges will be looking at the strategy, creativity and results of campaigns.
Nick Smith, a member of the DMA's Door-to-Door Council, said: "This is a great opportunity for agencies and clients to showcase their work, and have the chance to be recognised as producing the industry's most effective Door Drop campaign."
Entries must be in by December 12, and the winner will be revealed at the DMA Door-to-Door Conference.
