We want to assure you, as a Dunkin’ customer and member of the DD Perks program, that both our restaurants and the DD Perks program are operating the same as always to keep you runnin’. We’ll continue filling you up on great coffee and food options while you earn points toward your favorite free beverages.

On behalf of your local Franchisee-owned Dunkin’, we thank you for being a member of DD Perks.

Sincerely,

Scott Murphy, President, Dunkin’ Americas
