Can I stop a UAE company from using my data for marketing under the PDPL?

Yes. The UAE Personal Data Protection Law (Federal Decree-Law No. 45 of 2021) recognises your right to object to the processing of your personal data for certain purposes, and direct marketing is a typical example where you can require a business to stop. Where a company uses your data to send you promotional communications, you can withdraw any consent it relied on and object to further marketing processing. In practice you do this by using the opt-out or unsubscribe mechanism the business provides, adjusting your account preferences, or sending a written request to its privacy contact asking it to cease marketing to you. Once you object to marketing, the controller should stop using your data for that purpose, though it may continue to process the same data for other lawful purposes unrelated to marketing, such as fulfilling an order or meeting a legal obligation. Note that electronic marketing is also subject to other UAE telecom and consumer rules. If a business keeps marketing to you after you have clearly opted out, you can raise it with the UAE Data Office.
