DKIM Setup Checklist

1. Copy your DKIM selector and value from your Mailpro account.

   • Name/Host: <selector>._domainkey
   • Value: the long DKIM string provided
   • TTL: 300–3600 seconds (typical)
3. Wait for DNS propagation (can take up to a few hours).
4. Click Verify in Mailpro and send a test email.
5. Optional: rotate keys periodically and align the From: domain with the DKIM signing domain.
