Inbox placement testing across 115+ seed addresses + DMARC.
GlockApps tests placement. MailKite provides the sending infra with live DNS status.
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 GlockApps",
html: "<p>Sent in milliseconds via MailKite.</p>",
}); GlockApps is a deliverability testing tool with seed-list inbox placement (115+ addresses), 50+ blocklist monitoring, DMARC analytics, Postmaster integration, and an API.
