Merseyside-based CDMS said that London-based Transactis would continue to operate under its existing brand with its 30-staff inventory remaining unchanged.
CDMS added that the data processing business would help it to offer an end-to-end service while bolstering its multi-channel marketing offering.
Stephen Clark, chief executive of CDMS, said the acquisition was "a very good fit" that gave the company the ability "to offer a truly end-to-end proposition in direct marketing services".
He added: "The combined services that Transactis and CDMS offer will give clients the opportunity to improve speed to campaign launch and with increased effectiveness while reducing the cost of success."
The move will also allow Transactis to offer its members a print and paper management service.
Chris Morris, managing director of Transactis, said: "The tie-up with CDMS allows us to extend those services to offer our members and clients a complete targeting, digital printing and delivery service plus highly targeted digital campaigns at very competitive prices."
Last year, CDMS invested in two InfoPrint 5000s and two Xerox DocuTech 180 machines to grow its transpromo operation.
