03 — How it works

No templates marketplace, no drag-and-drop maze. Domain, template, credentials, send — and you can see exactly what happened to every message.

  1. STEP 01

    Verify your domain

    Add one domain. Copy the SPF, DKIM and DMARC records into your DNS provider and hit “Verify DNS”. We look them up — no guessing.

  2. STEP 02

    Generate a template

    Describe the email, choose the type and brand color. Tweak anything in the visual editor, preview on desktop and mobile, save.

  3. STEP 03

    Connect your app

    Create an API key or SMTP credentials. Copy a ready snippet for React, Node.js, Python, PHP or WordPress — with notes on what to replace.

  4. STEP 04

    Send and watch

    Emails go through a Redis queue with retries and rate limits. Every message has a log, a timeline and a Message-ID you can search.

04 — SMTP & API

Use an API key from your backend, or point any framework's mailer at the relay. Same validation, quotas and logs either way.

const res = await fetch("https://your-app.com/api/email/send", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.POSTNOVA_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <hello@acme.com>",
    to: "customer@example.com",
    templateId: "tmpl_welcome",
    variables: { name: "Ada" },
  }),
});

Saves back to HTML — tables and inline styles stay intact, so what you see is what Outlook gets.

06 — Analytics

Volume, delivery, bounces and failures per day. Open and click tracking exists, but it's opt-in per campaign — off by default.
