Mailchimp's transactional email API.
Mandrill requires a Mailchimp account. MailKite is standalone inbound-first infra with unlimited free domains.
A minimal, copy-paste starter. Swap in your own domain and API key.
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 Mandrill (Mailchimp)",
html: "<p>Sent in milliseconds via MailKite.</p>",
}); Mandrill is Mailchimp's (Intuit) transactional email API, offered as an add-on to a Mailchimp account. It provides API + SMTP, inbound email parsing, webhooks, and a rules engine.
