Sending Domains

Every email sent through Molted Email must come from a verified domain. This protects your sender reputation and ensures email providers trust your messages.

Why verification is required

Unverified domains are blocked by the policy engine with no_verified_domain. This prevents unauthorized sending and protects the platform's shared IP reputation.

Adding a domain

1. Go to Dashboard > Domains in the portal.
2. Click Add Domain and enter your domain (e.g., notifications.yourcompany.com).
3. You'll receive three DNS records to add.

DNS records

DKIM

A TXT record that adds a cryptographic signature to your outgoing emails. Recipients use this to verify the email was sent by an authorized server and wasn't tampered with in transit.

SPF

A TXT record on your domain that authorizes Molted Email's sending servers. This tells recipient mail servers that our IPs are allowed to send email for your domain.

DMARC

A TXT record that specifies what recipient servers should do with emails that fail DKIM or SPF checks. We recommend starting with a p=none policy and moving to p=quarantine or p=reject once you've confirmed everything works.

Verification

After adding the DNS records to your DNS provider, click Verify in the portal. DNS propagation typically takes a few minutes but can take up to 48 hours.

Once verified, the domain status changes to Active and you can start sending.
