Email starts with a domain you own. Add it under Domains, publish the DNS records, and wait until it verifies. Live sends use a from address on that domain.
A template is optional. You can send HTML or text in the request, or save the message on Templates and pass its id. The Quickstart is the full first-send walkthrough, including the API key.
- Domains — DNS and verification.
- Templates — reusable HTML and variables.
- Emails API — send, retrieve, and list.
