3. Data processor obligations (GDPR Article 28)
When you verify contact databases with MailCheckup, you retain full ownership as the Data Controller. MailCheckup operates strictly as your Data Processor. We execute verification handshakes solely upon your instructions, process records ephemerally in RAM, and never cross-reference uploaded emails to build secondary sales leads or commercial directory services.
Our standard Data Processing Addendum incorporates European Commission Standard Contractual Clauses (SCCs) to govern transatlantic data flows, guaranteeing that your organization remains compliant with European and UK data protection mandates.
4. Voluntary seven-day refund guarantee
We stand firmly behind the quality and empirical accuracy of our verification engine. All on-demand credit pack purchases are backed by our voluntary 7-calendar-day refund policy. If you purchase credits and decide MailCheckup is not the right fit for your workflow, submit a request to billing@mailcheckup.net within seven days for a direct Stripe refund of your unused credits.
