The ePrivacy Directive particularises and complements GDPR. Where Article 13 sets a special rule for sending unsolicited communications, do not skip that rule because personal-data processing also has a GDPR lawful-basis analysis. GDPR still matters for consent quality, transparency, records, downstream processing, rights handling, and data minimisation around contact data and suppression lists.
Article 13 also leaves implementation choices to Member States for cases outside the prior-consent and customer-soft-opt-in provisions, and it requires protection for subscribers other than natural persons under Community law and applicable national law. Use this page for the EU baseline, then check the national law for the recipient market before relying on a call, fax, B2B, corporate-subscriber, enforcement, or penalty conclusion.
