The agency prevailed in a four-way competitive pitch and will work with Yodel’s in-house team.
The campaign will focus on increasing Yodel’s share of voice in the industry as well as redressing "lingering perceptions among media and consumers about poor service levels", the company said.
Chris Hewitt, chief executive of Berkeley, said: "Working with Yodel is a stake in the ground for the agency. It’s a fantastic addition to our growing client roster that already includes global giants and UK super-brands. We’re looking forward to the challenge of helping the brand gain the positive recognition it deserves."
