These commitments are set out in your agreement. ### Integration credentials Use a separate API credential for each integration and revoke it without changing the others. These controls are also available to self-service accounts. ### Service levels Put availability targets, support response times and any service-credit terms in the service-level agreement (SLA). API workflows ## Where to check addresses in your system **SaaS product** ### Addresses you submit Email addresses entered during registration or when accepting an invitation. ### When to check Call the API from your backend before creating the account record. Keep the API credential on your server. ### What the API returns A status, recommended action and reason codes. If the response is pending, retrieve the result after the returned retry interval. ### How you use the result Apply your signup policy to the evidence. Show suggested corrections and send your own confirmation email when mailbox control matters. Verification does not establish that the user owns the address. **Marketing database** ### Addresses you submit Email addresses from your existing customer database or a list you are preparing to import. ### When to check Your system sends one request per address before an import or when existing evidence needs updating. Emvero does not provide a file uploader or hosted bulk job. ### What the API returns A status, recommended action and reason codes for each completed check. Your system saves those fields against the corresponding record. ### How you use the result Use your sending policy to separate addresses with permanent technical failures from those needing review. Verification does not establish permission to send marketing messages. **Lead platform** ### Addresses you submit Email addresses submitted through lead forms, event registrations or partner referrals. ### When to check Check an address before your system scores, routes or follows up on the lead. ### What the API returns A status, recommended action and reason codes identifying findings such as a disposable domain, role account or likely typo. ### How you use the result Use the findings in your lead-handling rules. A role account or disposable domain may need different treatment; neither signal alone establishes that the address is invalid. Security and procurement ## Information for your security review The security page describes how verification handles data. Ask sales for the processing terms and supporting documents your procurement review requires. ### How the service handles requests - Mailbox checks stop before message data is sent. No verification email is delivered. - The API returns structured evidence and reason codes, without raw mail-server reply text. - Integration credentials can be revoked independently. - Requests are limited per caller and source network. - SMTP probe evidence does not trigger rejection. Deterministic failures, such as malformed input or a nonexistent domain, can. - The request service and mailbox-check workers use separate network zones and outbound-connection policies. ### Processing terms and documentation - Encryption: TLS 1.3 in transit, AES-256 at rest - Retention and deletion: Verification records are retained for 30 days. Deletion is available on request. - Processing and storage: EEA only; stored in Germany - Data processing agreement (DPA): Signed on request - Certifications: None held today - Sub-processors: Hetzner Online GmbH for hosting and storage in Germany; FastVPS OÜ for the probe fleet in the EEA, with a planned move to OVHcloud; Google for website analytics.

Twelve million addresses through the API since, and the number that matters is the one that stopped moving: our sender reputation.” Head of CRM · B2B marketplace · 400 employees ## Discuss your purchasing requirements Tell sales your expected volume, where verification fits into your system, and which security documents or purchasing terms you need.
