TypeScript SDK
npm install emailmate. One client for send, domains, and inboxes. Resend-shaped API if you are migrating.
Email for developers.
Send transactional email with a TypeScript SDK. Same 50k as Resend Pro — half the bill.
3,000 emails free. No card.
import { EmailMate } from "emailmate";
const em = new EmailMate(process.env.EMAILMATE_API_KEY!);
const { id } = await em.emails.send({
from: "hello@yourdomain.com",
to: "user@acme.com",
subject: "Hello from EmailMate",
html: "<p>It works.</p>",
text: "It works.",
});First-class developer experience
TypeScript, REST, and MCP. We do not ship Python or Go SDKs yet.
REST
POST /v1/emails. Domain-scoped em_ keys. OpenAPI. No SMTP in v1 — we ship the API, not a relay.
MCP
https://mcp.emailmate.dev/mcp on every plan. Default tools are send, domains, logs, keys. Inbox is opt-in.
Webhooks that actually fire
HMAC-signed. Free plan included. Point them at your app or your agent.
- email.sent
- email.delivered
- email.bounced
- email.complained
- email.received
React Email
Write templates in React. Render HTML. Send the string. We do not make you learn a new template language.
Deliverability you control
- DKIM, SPF, DMARC, custom MAIL FROM
- Fail closed on From — you cannot send as a domain you do not own
- Suppressions and reputation pause
- Your SES if you want the AWS bill (BYOK $5)
Half Resend.
Same volume rungs. Caps pause sends — no $0.90/1k surprise.
