Email finding + verification + cold outreach.
Hunter finds prospects. MailKite sends the transactional email to them.
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 Hunter",
html: "<p>Sent in milliseconds via MailKite.</p>",
});Hunter is a B2B prospecting tool: find email addresses by domain (pattern discovery), verify them, and run cold-outreach campaigns. It's a sales/prospecting tool that uses email, not a deliverability tool.
