Purpose of data processing

Datamixx is a media agency specialising in the careful management and centralisation of consumer database access in order to support efficient planning and fulfilment of one to one direct marketing campaigns. DataMixx works with a number of partners who themselves collect the data we hold. DataMixx neither buys data from these partners nor re-sells it. All data is owned by the contributing source partner through which the data was originally collected and any partner can choose to withdraw access to it at any time. Marketing agencies and advertisers use us when they wish to rent data on defined and controlled usage terms for specific campaigns without having to go to multiple different sources. All partners are declared to advertising partners to enable source audit.


The core areas we support are:


  • The sending of relevant marketing communications

  • Verification and enhancement of customer and marketing databases

  • Enhance targeting relevance through market research, analysis, segmentation and profiling

  • Identity verification, credit and risk management, revenue collection, database tracing activities


We ensure the following:


  • Data is processed fairly and lawfully

  • Data is processing is compatible with the purpose it was collected for

  • Data is accurate, relevant and up to date.

  • Data is held only as long as is necessary

  • Data is kept securely


Use of Email

Legal basis for processing: consent


If you give permission to be contacted by advertisers via email, DataMixx might help identify relevant advertisers and support the email communication to you.  DataMixx does not ever sell this information outright to any advertiser.  Any email you might receive will always be sent on behalf of the source to whom you have given your consent to be contacted by and will always be identified as having originated from said source you have consented with.  This approach is described as a 'host emailing' where the 'sender' represents the holder of your consent for such communications. Any email received will be clearly identified as having originated from the original data controller.  Their details will also always be provided – name, address, telephone number.


Use of postal data

Legal basis for processing: Legitimate interest


If you give permission for advertisers to contact you by post we may make your postal address available for them to do so, governed by strict usage terms and monitoring tools, and provided you have not registered with the MPS

Use of telephone data

Legal basis for processing: Legitimate interest


If you give permission for advertisers to contact you by phone we may make your number available for them to do so, governed by strict usage terms and monitoring tools, and provided you have not registered with the TPS.

Use of linkage

Legal basis for processing: Legitimate interest


Data can be used for linkage purposes - linking offline data with online IDs for targeting and identity resolution purposes. Third party clients, such as third parties operating in the marketing technology sector, can associate information they have collected about you with certain identifiers linking personal data with cookies and mobile IDs helping marketers to deliver a more personalised and appropriate service. The types of data that can be used for linkage purposes will include name, postal address, phone number and email address.
