Common Questions

Frequently asked questions

Everything you need to know about Altnera Email Verification

Do you ever send an email during verification?

No, we never send emails during verification. We perform real SMTP handshakes with mail servers to verify mailbox existence without actually delivering a message to the recipient's inbox. This ensures zero impact on your sender reputation.

Is my data secure and compliant?

Absolutely. We take data security seriously:

  • All data is encrypted in transit (TLS) and at rest
  • GDPR-compliant processing with EU data residency options
  • SOC 2 Type II aligned security controls
  • Regular security audits and penetration testing
Do you support bulk verification?

Yes! We support bulk verification for files up to 5 million rows. Our system automatically deduplicates, normalizes, and streams results as they're processed. You can upload CSV or TXT files through our dashboard or API.
