Domain Verification
Authenticate your sending domain to ensure maximum deliverability and brand protection.
1Add Your Domain
Head to the Domains section in your dashboard and click Connect. Enter your root domain (e.g., example.com). Transmit will immediately provide instructions for DKIM verification.
2Configure DNS Records
You must add three CNAME records to your DNS provider (Cloudflare, AWS Route53, etc.). These records allow Transmit to sign your emails with DKIM.
Example Configuration
Type
CNAME
Hostname
[token]._domainkey.example.com
Value
[token].dkim.amazonses.com
Tip: Some DNS providers append your domain automatically. If so, only enter the first part (e.g., [token]._domainkey).
3Verification & Reputation
Once DNS records are added, click Verify DNS. Transmit checks for DKIM, SPF, and DMARC alignment.

Can I use multiple domains?
Yes, Transmit supports an unlimited number of domains. Each can be configured for both outbound sending and inbound receiving.
