After adding a custom domain, add the DKIM, SPF, DMARC, and MX records
Sentvia returned in GoDaddy.
Open DNS management
GoDaddy → My Products → your domain → DNS → Manage Zones / Add Record.
Enter the subdomain part only
GoDaddy automatically appends your domain to the Name field. So for a record named
token._domainkey.mail.yourco.com, enter just token._domainkey.mail — without the
trailing .yourco.com. (For a record at the domain root, use @.)
Add DKIM (CNAME ×3), SPF + DMARC (TXT), and MX
Add each record with its Type, the Name adjusted as above, and the Value/Points-to exactly as
shown. MX records use Priority 10.
The most common GoDaddy mistake is leaving the full hostname in Name — GoDaddy then creates
token._domainkey.mail.yourco.com.yourco.com. Enter only the part before your domain.
POST /domains/{id}/verify to re-check.
