The group will measure companies' opt-out rates and benchmark how they compare to their competitors and other industry sectors, as well as to national opt-out rates.
The aim is to establish trends across participating companies' sectors, other industry sector averages, and MPS and TPS rates. It will also aim to address the reasons why an increasing number of consumers are opting out, and provide companies with advice on how to reduce this.
"This project addresses a real client-side need and is vital if we are to tackle the number of consumers who are opting out," said tank! founder Sean Larrangton White.
