One endpoint. Six ways to call it.

Official SDKs for every major stack, plus a standard SMTP relay for the CMS and store platforms that don't do REST.
Node.js
import { Configuration, PartnerEmailSendApi } from "@splashifypro/sdk";

const api = new PartnerEmailSendApi(
  new Configuration({ accessToken: process.env.SPLASHIFY_KEY })
);

const { data } = await api.send({
  from: "[email protected]",
  to: ["[email protected]"],
  subject: "Welcome aboard",
  html_body: "<h1>Hi there</h1>",
  text_body: "Hi there",
  category: "transactional",
});

console.log(data.message_id);

Everything to ship email at scale

Built for developers. Priced for everyone.

Sending identities, configuration sets, templates, webhooks and suppression, at a flat ₹0.03 per email.

Sending domains

Send from your own domain, signed

Add three DNS records once per domain: SPF, DKIM and DMARC. Every email is DKIM-signed with your domain, so inboxes see your brand, not ours.
  • Pending domains checked every 15 minutes
  • Works with Cloudflare and most DNS hosts
  • Or verify a single sender address

Webhooks

Know what happened to every email

Pick the events you want: send, delivery, bounce, complaint, open, click and reject. Each one reaches your HTTPS endpoint signed with HMAC-SHA256, and failed deliveries are retried.
  • Event destinations per configuration set
  • Signed payloads you can verify
  • Retries when your server is down

Deliverability

Bounces and complaints handled for you

Hard bounces go on your suppression list the moment they happen, complaints are honoured and one-click unsubscribe is added for you. Sends to suppressed addresses are rejected and never billed.
  • A suppression list per account
  • Bounce and complaint rates on your dashboard
  • Sending pauses itself above 10% bounces or 0.5% complaints

Questions developers ask before signing up

Still curious? The full docs cover every endpoint.

There isn't one. We run the whole sending pipeline ourselves (SMTP, DKIM signing and bounce handling), so nobody adds a margin in between. ₹0.03 covers transactional and marketing alike; the only add-on is dedicated IPs at ₹350 a month. GST at 18% applies on Indian invoices.
