How MailKite fits

SocketLabs Spotlight monitors multiple ESPs. MailKite can be one of your send/receive providers.

Send email from SocketLabs with MailKite

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

send.ts

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

// One API, your own DKIM-signed domain — no mail server to run
const mailkite = new MailKiteClient({ token: process.env.MK_API_KEY! });

await mailkite.send({
  from: "you@yourdomain.com",        // any address on a verified domain
  to: "user@example.com",
  subject: "Hello from SocketLabs",
  html: "<p>Sent in milliseconds via MailKite.</p>",
});

Read the sending quickstart

SocketLabs is an email delivery platform that has pivoted to email observability — its Spotlight product monitors and routes across providers (Mailgun, Bird, SendGrid) with a RuleEngine for multi-provider sending. Useful for teams running more than one ESP.
