It is not known whether he has a job to go to.
According to a DMA statement, his responsibilities will be shared between the DMA’s directors and senior staff until a successor is appointed “later this year”.
Keitch was promoted to the brand and membership role in June last year. The role was created as part of a restructure of the Association aimed at refocusing its role in the direct marketing industry.
Prior to this, he was the DMA’s director of media channel development and environmental affairs for three years.
Keitch will continue with his day-to-day duties until the end of March, and will serve as the organisation’s media spokesman through to July.
Keitch says: “I’m proud of what I’ve achieved in setting the DMA on a steady course of change that will ensure it can continue to represent the interests of the direct marketing industry today and far into the future.”
