2

Verify Domain & Add Email

2.1 Add Your Domain

Add your domain and configure DNS records (SPF, DKIM, DMARC).

Dashboard → Mail Settings → Identities
Add domain: yourdomain.com
Add DNS records provided → Wait for verification (usually 5-10 minutes)

2.2 Create Email Address

Once domain is verified, create an email address under that domain.

Create email: noreply@yourdomain.com

✅ Verified emails under verified domains are instantly ready to use

  -d '{
    "channel": ["email"],
