1) Learn the product workflow

Cold Mail Server works as a workflow: identity setup -> sending auth -> campaign execution -> monitoring.

  • Domains establish trusted sender identity.
  • Mailboxes are your sending identities tied to domains.
  • Mailbox Auth Keys connect your sending tool securely.
  • Email Logs show delivery outcomes and message-level diagnostics.
  • Settings and team controls keep operations consistent.

2) Add your first domain

Add a domain before creating mailboxes and sending emails.

  • Go to Domains and click Add Domain.
  • Enter your domain name and save.
  • Copy the DNS records shown in the domain details page.
  • Add those records in your DNS provider and click Verify DNS.

3) Create a mailbox and auth key

Mailbox plus auth key is what your sending app needs.

  • Open Mailboxes and click Add Mailbox.
  • Choose your verified domain and mailbox name.
  • Open the mailbox auth key section and create a new key for that mailbox.
  • Copy the key immediately and store it in your sending tool securely.

4) Send and confirm your first test email

A test send confirms setup is complete.

  • Send a test email from your sending tool using your mailbox and mailbox auth key.
  • Open Email Logs and filter to Sent to confirm delivery status.
  • If needed, open message details to inspect headers and content.
  • Once successful, continue to warm up and scale gradually.
