Domain Verification Process

Add Domain: Submit domain configuration with your account ID
DNS Records Generated: System automatically creates three CNAME records
Add DNS Records: Add the generated CNAME records to your domain's DNS settings
Wait for Propagation: Allow time for DNS changes to propagate (5 minutes to 48 hours)
Verify Domain: Use the verification endpoint to check DNS record configuration
Check Results: Review verification response to see which records are valid
Retry if Needed: Re-run verification after additional propagation time if some records show as invalid
Email Sending: Domain is ready for email sending once all records show "isValid": true

Common Issues and Solutions

Issue	Cause	Solution
All records show `isValid: false`	DNS records not yet added or propagated	Wait for DNS propagation (5 min - 48 hours) and retry
Some records valid, others invalid	Partial DNS configuration or caching	Check DNS provider settings and wait for full propagation
Verification endpoint returns 400	Domain not found in account	Ensure domain was properly added to account first

Example Use Cases

Register Company Domain

Setting up a primary company domain for email sending:

{
  "emailAddress": "[email protected]",
  "domain": "company.com",
  "accountId": "903e1cef-84b3-4500-a9a5-b2ca219f76f5",
  "dnsRecords": [
    {
      "host": "cm2903e1cef84b34500a9a5b2ca219f76f5._domainkey.company.com",
      "type": "CNAME",
      "value": "903e1cef84b34500a9a5b2ca219f76f5cm2._domainkey.email.cm.com.",
      "isValid": false
    },
    {
      "host": "cm903e1cef84b34500a9a5b2ca219f76f5.company.com",
      "type": "CNAME",
      "value": "903e1cef84b34500a9a5b2ca219f76f5.email.cm.com.",
      "isValid": false
    },
    {
      "host": "cm1903e1cef84b34500a9a5b2ca219f76f5._domainkey.company.com",
      "type": "CNAME",
      "value": "903e1cef84b34500a9a5b2ca219f76f5cm1._domainkey.email.cm.com.",
      "isValid": false
    }
  ]
}

Add Subdomain for Marketing

Adding a subdomain specifically for marketing campaigns:

{
  "emailAddress": "[email protected]",
  "domain": "marketing.company.com", 
  "accountId": "903e1cef-84b3-4500-a9a5-b2ca219f76f5",
  "dnsRecords": [
    {
      "host": "cm2903e1cef84b34500a9a5b2ca219f76f5._domainkey.marketing.company.com",
      "type": "CNAME",
      "value": "903e1cef84b34500a9a5b2ca219f76f5cm2._domainkey.email.cm.com.",
      "isValid": false
    },
    {
      "host": "cm903e1cef84b34500a9a5b2ca219f76f5.marketing.company.com",
      "type": "CNAME",
      "value": "903e1cef84b34500a9a5b2ca219f76f5.email.cm.com.",
      "isValid": false
    },
    {
      "host": "cm1903e1cef84b34500a9a5b2ca219f76f5._domainkey.marketing.company.com",
      "type": "CNAME", 
      "value": "903e1cef84b34500a9a5b2ca219f76f5cm1._domainkey.email.cm.com.",
      "isValid": false
    }
  ]
}

Multi-Domain Setup

Managing multiple domains for different business units:

Main Website: company.com
Support Portal: support.company.com
Marketing Campaigns: promo.company.com
Customer Portal: portal.company.com

Each domain will receive the same three CNAME records (with domain-specific hostnames) but pointing to the same account-specific email infrastructure, ensuring consistent email delivery across all business units.
