The DMA Code
The DMA Code is an ethical framework that sets the standard for the data and marketing industry. All DMA members must commit to the Code.

The DMA Code is overseen by the DMA's Governance Committee and enforced by the DMC. It promotes transparency, authenticity and responsibility. These qualities are key to building trust, loyalty and long-term business success. We investigate any complaint that falls within the remit of the Code. However, our scope does not extend to investigating or adjudicating on the People Principle contained within the Code.
Under the hero principle ‘Put Your Customer First‘, the Code promotes the evolution of marketing as a genuine exchange of value. Businesses thrive and their customers benefit.
Respect privacy
Be honest and fair
Be diligent with data
Take responsibility

Other regulatory and co/self-regulatory organisations apply rules to data & marketing such as the Information Commissioner’s Office which regulates data protection and other information rights legislation, ensuring compliance with laws like the Data Protection Act, the General Data Protection Regulation (GDPR) and the Privacy and Electronic Communications Regulations 2003. You can access guidance on your data protection rights on the Information Commissioner's Office website here.
The Advertising Standards Authority’s CAP/BCAP Codes also contain a wide range of rules relating to data & marketing.
