Get startedPlans and availability

What ColdMail provides

  • SPF, DKIM, DMARC, and MX configuration
  • Domain and mailbox provisioning in the same workflow
  • Domain health visibility for ongoing checks

A practical workflow

  1. Confirm ownership and DNS access for the sending domain.
  2. Complete mailbox provisioning and review the configured records.
  3. Allow DNS changes to propagate, then verify authentication with a test message before launching.

Example in practice

When an agency adds a new client, record the sending domain and its owner first. After setup, check that the test message authenticates as that domain. Repeat the check when a sender, DNS provider, or signing key changes.
