The awards ceremony, which acknowledges excellence in the direct marketing industry, will be held on June 6 at London's Millennium Mayfair Hotel. It includes categories for achievement in innovation, creativity and branding across the 12 categories.
Professor Derek Holder, IDM managing director, said: "The IDM Business Performance Awards continue to be the only awards that reward exemplary direct marketing that measurably improves business success."
The IDM chose Johnson, the former editor of The Spectator magazine and current MP for Henley-on-Thames, for his trademark wit and charisma.
"We are delighted that such an inspired speaker as Boris Johnson has agreed to speak," Holder said.
