Security & Trust Center

Your list is sensitive. We treat it that way.

Email lists are some of the most valuable data a business owns. We encrypt yours in transit, restrict who can touch it, and tell you exactly where it goes — because trust you can't inspect isn't trust.

Security & compliance

Specifics, not adjectives.

Anyone can write 'enterprise-grade'. Here is exactly what we commit to.

GDPR

Compliant

Lawful processing, data-subject rights and a DPA. EU data handled under documented, enforceable terms.

How we handle your data

Six commitments we'll put in writing.

Not vague promises — specific, inspectable practices your security team can verify.

Encrypted end to end

Every list is encrypted in transit with TLS 1.3. Keys are managed and rotated — never embedded in code or shared.

Retained only as long as needed

Uploaded lists are processed and purged on a strict schedule. Delete a job and its data is gone — verifiably, not just hidden from the UI.

Never sold, never shared

Your contacts are yours. We don't sell, rent or build marketing databases from your lists. Verification is the product — your data isn't.

Least-privilege access

Access to production is scoped, logged and reviewed. Engineers see what they need to operate the service — and nothing more.

Hardened & monitored

After a real incident, we rebuilt the platform on hardened infrastructure with locked-down internal services and automated availability checks.

Data residency you can ask about

Need EU-only processing or a DPA for your compliance team? Talk to us — we'll put the specifics in writing.

Data lifecycle

Upload, verify, return, purge.

Your data follows one controlled path and leaves on a schedule. Here's the whole journey — nothing happens to your list that you can't trace.

  • 01Upload. Your list arrives over TLS 1.3.
  • 02Verify. Addresses are checked in an isolated pipeline. Results are scored, never enriched or resold.
  • 03Return. You download clean results or sync them back to your tools. The verdict is the only thing that leaves.
  • 04Purge. Source data is deleted on schedule — or instantly when you delete the job. Gone means gone.

Transparency

Our sub-processors, in the open.

The vendors that help us run the service — what each one does and where. A DPA and the full current list are a request away.

Radical transparency

We'll never fake a green light.

The same honesty that drives our security drives our verdicts. When an address is genuinely undeterminable, we say so — and we don't charge you for it. You pay only for answers we're sure of, your credits never expire, and we show our work on every result. Security and honesty aren't separate features here; they're the same promise.

We were hit. We rebuilt in the open — and locked it down.

Radical transparency includes owning what went wrong.
