The agency will be responsible for working on TMG's first dedicated loyalty programme launching this month. The newspaper group have already signed up Carluccio's and Debenhams as partners.
Flourish will develop direct response creative on projects that will span across the Group's new subscriber rewards and recruitment programme as part of its plans to increase penetration and retention of its customer base.
The loyalty programme will offer subscribers to The Daily Telegraph and The Sunday Telegraph a card that entitles them to a range of offers. It will be overseen by TMG loyalty director Graham Horner, who recently joined the media group from Coca-Cola.
TMG already has a relatively big subscriber base – it accounts for nearly half of the headline circulation of its titles. The company hopes to boost these still further by offering incentives, such as a free coffee at Debenhams.
Horner said: "Customer engagement has become a strategic priority for our business. I look forward to build and deliver a loyalty proposition that's right for our brand and right for our readers."
