Achieving corporate membership required the firm to undergo a stringent application process, taking stock of the Huddersfield direct marketing specialist’s financial stability, its trading behaviour since its establishment in 1996 and references from customers and suppliers.

Nicola Cummins, new business development manager, said: “We’re thrilled to have been recognised by the DMA in this way, the process has required us to scrutinise our business and our approaches to direct mail and marketing.

“It’s good to know that a nationally respected body such as the DMA has recognised our efforts, allowing us to earn the trust of our customers and their custom.”

With the high-profile advent of GDPR, and with socially responsible marketing practices high on the agenda, the Huddersfield company hopes its membership will provide reassurance to existing and future customers.

Propack, which also has a presence in London, specialises in direct mail, marketing, digital print, distribution and postage. It serves many well-known blue-chip clients including Sky Bet, Travis Perkins and Go Outdoors, as well as a raft of national charity clients.

It turns over £10m and employs 68 members of staff after hiring six new members in May in response to an influx of new business.

The DMA comprises the Data & Marketing Association and the Institute of Data & Marketing (IDM) and represents more than 1,000 members across the UK's data and marketing landscape.
