Effective DNS record configuration is crucial for proper email functionality. Here's a comprehensive guide to setting up essential email-related DNS records.

2. Click Add Record and select MX
3. Enter @ in the Host field (or subdomain if applicable)

DKIM and SPF Records

These TXT records authenticate your email and prevent unauthorized sending:

1. Access DNS Settings > Custom Records
2. Select TXT or CNAME type
3. Enter host information (or @ if none provided)

DMARC Records

DMARC validates your domain for email campaigns:

1. Go to DNS Settings > Custom Records
2. Select TXT type
3. Enter _dmarc in Host field
4. Add provider's TXT record value

Note: Only one DMARC record per domain is allowed. Multiple records must be combined using commas.

   • Service name (_smtp, _sip)
   • Protocol (_tcp, _tls)
   • Priority/TTL (optional)
   • Weight (single digit)
   • Port number
   • Target URL

2. Add record:

   • Type: SRV

   • Priority: TTL number (if applicable)
   • Data: Weight Port Target
   • Save changes
