Nylas

Unified API for email, calendar, and contacts across providers.

How MailKite fits

Nylas wraps mailboxes you already have. MailKite provisions real addresses on your own domain — no existing inbox required.

Receive email into Nylas via MailKite

A minimal, copy-paste starter. Swap in your own domain and API key.

webhook.ts

import { verifyWebhook } from "@mailkite/client";

// MailKite POSTs every inbound email at your domain as JSON.
// Point a route at this handler in the MailKite dashboard.
export default async function handler(req: Request) {
  const raw = await req.text();
  const sig = req.headers.get("x-mailkite-signature") ?? "";

  // Reject anything not signed by your webhook secret
  const ok = await verifyWebhook(sig, raw, process.env.MK_WEBHOOK_SECRET!);
  if (!ok) return new Response("bad signature", { status: 401 });

  const email = JSON.parse(raw);
  // Route into Nylas: open a ticket, create a task, store a record
  await routeIntoName(email);   // email.from · email.subject · email.text

  return new Response(JSON.stringify({ ok: true }));
}

Read the inbound webhooks guide

Nylas is a unified API that connects to existing mailboxes (Gmail, Outlook, IMAP) and exposes email, calendar, and contacts through one API. It's strong for apps that need to read and act on a user's existing mailbox, rather than provision new addresses. It's an integration layer over other providers, not a mail platform itself.

Key features
