Manage your sending domains through the Lettr facade. This is useful for multi-tenant apps that onboard customer domains, or for automating DNS verification checks from an Artisan command or job. For the concepts behind domain setup (SPF, DKIM, DMARC, tracking domains), see Sending Domains.

Verify Domain DNS

After publishing the DNS records, trigger a verification check:
DNS changes can take time to propagate. If verification fails immediately after publishing records, wait a few minutes and try again. See Domain Verification troubleshooting for common issues.

POST /domains//verify

Delete a Domain

Deleting a domain stops all sending from that domain immediately. Emails sent from a deleted domain will fail with a validation error.
