Yes, you need GDPR for newsletters if you are a European company. The General Data Protection Regulation (GDPR) is a new regulation that went into effect on May 25, 2018.
The GDPR applies to all organizations with EU customers that process the personal data of EU citizens.
Organizations must take steps to ensure that their newsletters are compliant with the GDPR. The GDPR requires that organizations provide individuals with clear and concise information about their rights under the GDPR, and they must give individuals the right to access their personal data, request rectification of inaccurate data, and request erasure of their personal data.
In addition, organizations must offer individuals the right to object to their personal data being processed for marketing purposes.
If you are a European company and you send newsletters to EU customers, you should make sure that your newsletters are compliant with the GDPR. You can check to see if your newsletter is compliant by using the GDPR checklist provided by the ICO.
If your newsletter is not compliant, you should make changes so that your newsletter is compliant.
