Email risks in communications

When you deliver customer communications on behalf of brands, you carry the risk as well as the workload. A single misdirected email, weak identity checks, or unclear delivery evidence can become a client issue fast.

Mailock gives you encrypted delivery, recipient authentication options, and tracking, so you can send sensitive documents by email with more confidence - at the volumes your operation needs.

Controls and evidence

Built to support delivery obligations, audits, and oversight

Mailock helps communications providers align with:

  • UK GDPR expectations for protecting personal data in transit
  • Client contractual requirements for secure delivery and access controls
  • Evidence to support durable medium requirements where relevant
