FAQ
Do I need SMTP?
Not for the current flow. The HTTP API covers transactional send. A first-party SMTP relay (smtp.envimaily.com) is on the roadmap — we never hand customers SES SMTP credentials.
Is it Resend-compatible?
Payload shape and /emails + /v1/emails paths follow a Resend-like surface. See the migration guide.
Where is the markdown?
Every page has a raw version at /docs/<slug>.md plus a Copy as markdown button — useful for AI agents and GEO.
