Core Concepts
Custom Domains
Send from your own domain
Why use custom domains
- Better deliverability
- Brand consistency
- Builds sender reputation
Setup
- Go to Settings → Domains
- Click Add Domain
- Enter your domain
- Add the provided DNS records (DKIM, MX, TXT)
- Wait for verification (usually 10-30 minutes, up to 48 hours)
Using your domain
Specify in the from field when sending:
{
"to": "customer@example.com",
"from": "orders@yourdomain.com",
"subject": "Order confirmed",
"body": "<p>Your order has been confirmed.</p>"
}Troubleshooting
Domain won't verify:
- Check DNS records are correct
- Wait for DNS propagation (up to 48 hours)
- Remove conflicting DKIM records from other services
Emails going to spam:
- Warm up new domains with small volumes first
- Monitor bounce and complaint rates
