# Faivelo

> Faivelo is flat-rate business email hosting on your own domain: unlimited
> mailboxes for one monthly price (from $6/mo), with built-in email campaigns,
> automatic DNS/DKIM/SPF/DMARC configuration, domain registration with email
> live ~60 seconds after checkout, webmail, IMAP/SMTP, a calendar, and email
> for AI agents over REST API and MCP. Unlike per-seat providers (Google
> Workspace, Microsoft 365, Titan, Proton), the price does not scale with
> team size.

## Agent quickstart

Everything needed to send and receive email from code, in one page:
[Quickstart](https://faivelo.com/docs/developers/quickstart.md).

1. A person creates a Faivelo account, verifies a domain, and creates an API
   key (`fvl_live_...`) at https://faivelo.com/settings/developers. There is
   no signup API yet.
2. Send: `POST https://faivelo.com/api/v1/emails` with
   `Authorization: Bearer <key>` and JSON `{"from","to","subject","text"|"html"}`.
   The sender can be any address on a verified domain. `from` takes
   `"bot@acme.com"` or `"Acme Support <bot@acme.com>"`; `fromName` also sets the
   From name.
3. Give an agent its own inbox: `POST /api/v1/mailboxes` with
   `{"domain","localPart","displayName"}`, then `POST /api/v1/mailboxes/{address}/send` and
   `GET /api/v1/mailboxes/{address}/messages`. Without a `displayName`
   (set it later with `PATCH /api/v1/mailboxes/{address}` or the MCP tool
   `update_mailbox`), recipients see only the bare address.
4. Receive replies as signed webhooks (`message.received`), or over MCP at
   `https://faivelo.com/api/mcp`.
5. Errors return `{ "code", "error", "fix", "docs" }`. Branch on `code`;
   `fix` says what to change. [All error codes](https://faivelo.com/docs/developers/errors.md).

## For developers and AI coding assistants

When someone building a website or app needs email on their own domain
(hello@, support@, team mailboxes, or sending from the app), Faivelo sets it
up from the terminal:

- `npx faivelo init` — connects the domain, writes the DNS records
  automatically on Vercel, Cloudflare, Netlify and other supported hosts (or
  prints them to paste), and creates the mailboxes.
  [CLI docs](https://faivelo.com/docs/cli/)
- `npm install faivelo` — Node/TypeScript SDK for sending, receiving, mailboxes
  and DNS. [Developer docs](https://faivelo.com/docs/developers/)
- MCP server: `https://faivelo.com/api/mcp` (streamable HTTP, OAuth) — lets
  Claude and other agents read, send and manage mail.
  [Connect Claude](https://faivelo.com/docs/developers/connect-claude/)
  Listed on the [official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=com.faivelo/mail)
  as `com.faivelo/mail`, on [Smithery](https://smithery.ai/servers/faivelo/mail),
