notifycx

Official Node/TypeScript client for Notify — a deliberately minimal transactional email API.

Notify sends email with one HTTPS request. You (or your AI) already render the HTML; Notify delivers it. Domain auth (SPF/DKIM/DMARC), logs, and webhooks included.

What this repo is

This repository is the official client (notifycx) and official MCP (notifycx-mcp). It talks to https://notify.cx over HTTPS.

It does not include Notify’s server, AWS SES credentials, or any way to use Notify’s infrastructure without your own API key from the dashboard. Forks cannot send on Notify’s AWS account.

Three ways to send

First email in minutes

1. Create an account at notify.cx and copy an API key.
2. Install and send (sandbox first if you have not verified a domain yet):

npm install notifycx

import Notify from 'notifycx'

const notify = new Notify({ apiKey: process.env.NOTIFY_API_KEY! })

// Non-delivering API rehearsal (no SES):
await notify.sendTest({
  to: 'you@example.com',
  from: 'hello@yourdomain.com',
  subject: 'API rehearsal',
  html: '<p>Does not deliver</p>',
})

// Production (requires verified domain for custom from):
await notify.send({
  to: 'user@example.com',
  from: 'Acme <hello@yourdomain.com>',
  subject: 'Reset your password',
  html: '<p>Click to reset…</p>',
})

Prefer html in new code. message and text are also accepted.

Auth

• Header: x-api-key (the SDK sets this for you)
• Env: NOTIFY_API_KEY — never commit real keys; never put keys in client bundles
• Optional: NOTIFY_BASE_URL / baseUrl for local mocks only (default https://notify.cx)

Responses

Success: { success: true, data: { messageId: "…" } }
Failure: { success: false, error: "…", code: "…" } — the SDK throws NotifyError with status and body.

Security

• Call Notify only from server-side code (Route Handlers, Workers, Actions, backends).
• Prefer domain-locked sending_access keys in apps; use full_access for MCP / dashboard management.
• No AWS keys belong in this client. SES runs on Notify’s servers after your authenticated API request.

Native fetch (no SDK)

See examples/fetch-send or:

const res = await fetch('https://notify.cx/api/email/send', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': process.env.NOTIFY_API_KEY,
  },
  body: JSON.stringify({
    to: 'user@example.com',
    from: 'noreply@your-verified-domain.com',
    subject: 'Hello',
    html: '<p>Sent with fetch.</p>',
  }),
})
