Onboarding and compliance verification

Lettermint reviews new teams before unrestricted production sending. Verification protects deliverability for all customers and helps prevent abuse.

When verification matters

Unverified teams are limited to sending to (verified) team members only. Verify your account before moving customer-facing traffic to Lettermint.

Complete verification

  1. Create your team and first project.
  2. Verify a sending domain.
  3. Create a Project API token for your integration.
  4. Complete the compliance verification form.
  5. Send test-address scenarios to confirm routing and events.
  6. Wait for verification before sending production traffic to non-team recipients.

Information to prepare

  • Business or project description
  • Website or application URL
  • Expected sending volume
  • Email types you will send
  • How recipients opt in
  • Bounce, complaint, and unsubscribe handling
