Sendfeather documentation
Everything needed to get mail out of your app and into an inbox: sending, domains, and delivery.
Getting started
From sign-up to your first delivered email.
SMTP
Point any SMTP client at Sendfeather — no code required.
SMTP relay
An SMTP relay takes your message and delivers it to the recipient's server for you. What one does, why a relay beats sending from your own server, and what to check before picking one.
HTTP API
One POST per email, from any language or framework.
MCP server
Point Claude, ChatGPT, or Cursor at your sending data.
Laravel
The official driver — or plain SMTP with zero packages.
Domains & DNS
Two records to a verified domain — or none with Cloudflare.
Moving your mail
Bring mailboxes over from another provider without losing a message.
Delivery updates
Push every delivery event to your own endpoint.
