Lockwood joined Edge Marketing last year from Mastercard, where she was group head of marketing for Asia-Pacific, Middle East and Africa.
Patrick Pitcher, chairman of Edge, said Lockwood has assisted in "completely re-thinking" internal operations since joining the company.
“Natalie has made a tremendous impact on our business since joining us last year. Integration between digital, direct and data capabilities is just as important for us as it is for our clients," said Pitcher.
"Having proven this to both our clients and our staff, it was a very easy decision to appoint her to this new role,” he added.
