Marketing emails won't stop

Have you already told the company to stop marketing to you (objected or unsubscribed)?
Yes — and it keeps coming

Once you have objected, continuing to send you marketing is a straightforward violation — Article 21(3) says your data "shall no longer be processed" for direct marketing, full stop.

Keep the messages you received after your objection as evidence, note the date you objected, and complain to your national Data Protection Authority (Art. 77). This is one of the easiest complaints for a DPA to act on.
