No Data Processing Agreement needed. No data processor to audit. No cross-border data transfers to worry about. Your email lists stay on your machine - always.
Email addresses are personal data under GDPR. Every time you upload a list to a cloud validation service, you're transferring personal data to a third-party processor.
Cloud services require a DPA before you can legally share email lists. You need to verify the DPA covers your specific use case, review sub-processors, and maintain records of processing activities.
Many email validation services are US-based. After Schrems II, transferring EU personal data to US servers requires Standard Contractual Clauses, Transfer Impact Assessments, and supplementary measures.
Cloud validators often use sub-processors for infrastructure, analytics, and SMTP verification. Each sub-processor adds risk and requires documentation. A breach at any point in the chain is your liability.
Most cloud services retain uploaded email lists for 30+ days. Under GDPR, you need to justify this retention period and ensure deletion actually occurs. Can you verify data deletion at a third party?
BounceBuster is a desktop application that runs entirely on your computer. No data is uploaded, transmitted, or processed by any third party.
Since no personal data leaves your machine, there's no data processing to agree on. You are the sole controller and processor.
Your data stays on your hard drive. No servers in the US, no servers anywhere. Zero transfer risk.
BounceBuster has no cloud infrastructure, no analytics on your data, no third-party SMTP checks. The only network calls are DNS/MX lookups - which don't transmit email addresses.
Your email lists exist only on your machine, in your files. When you delete them, they're gone. No cloud server retains a copy.
If you need a Data Protection Impact Assessment, it's straightforward: the processing is local, the data doesn't leave the EU (or your machine), and there's no third-party access.
BounceBuster performs format, DNS, and MX record validation - the checks that catch roughly 90% of bounces - without sending a single email address to any server.
Validates email syntax against RFC standards. Catches typos, missing @ signs, invalid characters, and malformed addresses.
Checks that the email domain exists and is properly configured. Identifies domains that have expired or were never real.
Verifies that the domain has mail exchange records and is set up to receive email. No email is sent - just a DNS lookup.
Honest note: BounceBuster does not perform SMTP verification (which would require connecting to mail servers and sending probe commands). SMTP checks can catch an additional ~10% of invalid addresses, but they require sending data over the network - which defeats the purpose of local, privacy-first validation. For GDPR-conscious organizations, the privacy trade-off is clear.
Clean subscriber lists before campaigns without sending personal data outside the organization. No vendor risk assessment needed.
Recommend a validation tool that requires zero paperwork - no DPA, no DPIA complexity, no sub-processor audit.
Validate customer email lists from your Shopify, WooCommerce, or Magento export without sharing customer data with yet another SaaS tool.
