The restructured company will be located in two sites, at Merseyside and London, headed up by David Steele, who took over from former chief executive Stephen Clark in June.
He said: "Our services are geared towards turning clients’ transactional data into actionable insight, and then using that understanding to enable clients to set customer strategies, deliver engaging communication and drive business profitability.
"The Transactis data pool and customer transactions coupled with their reputation and industry profile makes Transactis the logical identity to take us forward."
Transactis' core offering will focus on customer insight and database management, personalised direct mail, image management and catalogue production as well as campaign management and execution.
Its print and mail operation, which are run from the Merseyside site, will be operated as Transactis Document Solutions, a division of Transactis.
Chris Morris, the previous managing director of the original Transactis company, will stay on as a non-executive director of the new business, which has clients that include Nationwide, Betfair, HM Revenue and Customs and Shop Direct Group.
"By putting the activities of the two operations together, we can extend services to both our clients and our members to boost their insight, targeting, digital print and delivery capability. That’s what the market wants," said Morris.
