DM Data is a UK direct marketing data company that says it collects data from other data controllers under legitimate interest and helps clients tailor products and services for marketing purposes. While it does not collect data directly from consumers, it acts as a data controller on behalf of suppliers and clients to facilitate data sharing for marketing activity.
This DM Data opt-out guide explains how to request suppression of your details, what suppression means, what information you may need to provide, and what to expect after submitting a suppression request through DM Data’s consumer page.
OptOutAI’s DM Data Opt-Out Review
DM Data’s suppression process is relatively straightforward. The page clearly explains what suppression is and provides a dedicated request form, along with alternative contact methods for consumers who want their details handled directly.
Speed: 4/5
The form is quite short and can usually be completed within a few minutes if you have the name, address or phone number shown on the communication you received.
Difficulty: 2/5
The process is fairly simple because it is based on one suppression form, but you still need to provide accurate details so DM Data can match your information correctly.
1. Start on the DM Data Consumer Suppression Page
Go to the DM Data consumer suppression page. This is the main page DM Data provides for consumers who want to have their details suppressed from its database. The page explains that DM Data collects information from other data controllers and uses it to support marketing activity for clients. It also states that DM Data will never obtain or share sensitive or financial information about you. Before filling in the form, it helps to keep the communication you received nearby, whether it was a postal mailing, phone call or another marketing contact, because the page suggests using the name and address shown on the mailing piece or the phone number where you were called.
2. Understand What “Suppression” Means
DM Data explains that, in most cases, it is preferable to follow the marketing industry practice of suppression rather than deleting an individual’s details entirely. Suppression means keeping just enough information to ensure your preferences are respected in future. This matters because if your details were deleted completely, DM Data says it would have no reliable way to check future marketing lists against your request, which could increase the chance of you being added back again later. So if your goal is to stop future marketing contact through DM Data’s systems, suppression is the route the company specifically recommends.
3. Enter Your Name and Contact Details
The suppression request form asks for your first name and last name, and it also allows you to add another individual if necessary. This is useful if more than one person in the household needs to be covered by the request. Next, the form asks for your address and/or contact number. You can enter your postcode and use the address lookup tool, or add the address manually. There is also a field for telephone if that is the contact detail that was used. The key thing here is accuracy. Use the name, address and telephone details exactly as they appeared on the marketing piece or call record where possible.
4. Add Your Email Address and Message
If you want confirmation, additional information or need to explain the issue in more detail, DM Data provides fields for an email address and a message. This is useful if you want to describe the communication you received or ask follow-up questions about the request. You do not need to overcomplicate the message. A short note explaining that you want your details suppressed, along with a reference to the marketing contact you received, is usually enough. If you have any special concern, such as repeated mailings or uncertainty about which address was used, this is the place to mention it.
5. Send the Suppression Request
Once the form is complete, click the button labelled Send my details for suppression. According to the page, the request will then be actioned by DM Data’s Consumer Services team. After submitting the form, it is sensible to keep a record of the details you entered and the date of submission. If you later need to follow up, this record will help you explain what request was made and when. The page also links to the company’s privacy policy if you want further information about the data it collects and how that information is handled.
6. Use the Alternative Contact Options if Needed
If you do not want to use the form, DM Data also provides direct contact details. The page lists the Compliance Manager at DM Data Ltd, Sunningdale, The Belfry, 13 Colonial Way, Watford, Hertfordshire, WD24 4WH for postal contact. It also provides the email address compliance@dmdata.co.uk and a Consumer Suppression Freephone number of 0800 031 4001. These alternatives can be useful if you need clarification, want to raise a more complex concern, or prefer not to use the online form. If you use one of these routes, it is still worth providing the same core details clearly so the request can be matched correctly.
Final Thoughts
DM Data provides a clear consumer suppression process and explains why suppression is generally preferred over complete deletion. For most users, the process is simple: go to the page, enter the relevant details from the marketing contact you received, and submit the request for suppression.
OptOutAI helps users find privacy settings, opt-out pages and removal routes across major platforms, data brokers and marketing databases. DM Data is only one part of your wider data footprint, so it is worth checking where else your personal information may be used for direct marketing or profiling.
