Verify domain

Check SPF, DKIM, and DMARC after configuring DNS.

When DNS records are published, verify the domain from the API or the dashboard wizard.

Verification via API

curl -X POST "https://api.mailingcore.com/domains/cldomainid/verify" \
  -H "Authorization: Bearer <JWT_access_token>" \
  -H "X-Tenant-Id: clxxxxxxxx"

Typical response:

{
  "spfStatus": "VALID",
  "dkimStatus": "VALID",
  "dmarcStatus": "VALID"
}

Possible states: VALID, PENDING, FAILED (per dashboard implementation).

If verification fails

Problem	Action
SPF not detected	Check a single TXT at root; no extra quotes
DKIM pending	Confirm host `mc1._domainkey` and full value
DMARC missing	Add `_dmarc` even with `p=none`
Slow propagation	Wait and retry; use `dig` or online DNS tools

After verification

Use fromEmail with that domain in POST /emails/send
Open and click tracking continues to work with your links
Hard bounces and complaints feed the suppression list automatically

Remove domain

DELETE /domains/:id — removes the domain from the tenant (requires JWT). Does not delete DNS records at your provider; clean them up manually if you stop using MailingCore.
