Caple has been at Future Publishing since 1996 and has been ad director for its Bath-based titles for the past year.
As a member of the board, her first task will be a review of the publisher's ad sales processes and structure.
Robert Price, the managing director of Future Publishing, said: "Jayne's promotion and appointment to the UK board are both well deserved and comes at a time when Future Publishing is moving forward, strengthening and growing its portfolios and UK business as a whole."
Caple began her ad sales career at the Auto Trader Group in 1989 before working for regional newspaper groups, including Bristol United Press.
