Domains & DNS

Add the domain

In Dashboard → Domains → Add domain, enter the domain you send from (yourdomain.com, not mail.yourdomain.com, unless that subdomain is what appears in your from address). cmdsend generates a unique DKIM keypair for it on the spot.

Publish the DNS records

The domain's page shows the exact values to copy. cmdsend uses BYODKIM — one DKIM record instead of the traditional three CNAMEs — plus a dedicated MAIL FROM subdomain so SPF aligns for DMARC.

Most providers add the domain to the record name automatically — if yours does, enter just send rather than send.yourdomain.com.

Wait for verification

Verification runs on its own — every 30 seconds for the first 10 minutes, then every 5 minutes, for up to 72 hours. You can also trigger an immediate check from the domain's page. DKIM and MAIL FROM verify independently; the domain is ready once both show success.

Most DNS providers propagate within 15 minutes, though some take a few hours. Nothing is required from you while you wait.

Send a test email

Once the domain is verified, send from any address on it.

await cmdsend.emails.send({
  from: 'hello@yourdomain.com',
  to: 'you@example.com',
  subject: 'Domain verified',
  text: 'Sending from my own domain.',
});

A 403 here means the domain is not verified yet — the message names the domain it checked.
