New Inbound email, validation and custom tracking domains

Email that just arrives.

One API to send transactional and marketing email from your own domain, receive replies and keep your lists clean. Built by Trivaan Digital on infrastructure we run ourselves.

send.js
await fetch("https://api.trivsend.com/emails", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.TRIVSEND_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <noreply@notify.acme.com>",
    to: "asha@example.com",
    subject: "Your sign-in code",
    html: "<p>Your code is <b>482913</b></p>",
  }),
});
// { "id": "3f2a1c9e-7b4d-4e8a-9c1f-2d6b8a0e5f71" }

Everything email, in one place

What your app needs after the first send, without stitching together five services.

Transactional API

Send one or a hundred emails per request, with attachments, tags, scheduling and idempotency keys for safe retries.

Your domain, authenticated

DKIM, SPF and DMARC from your own subdomain, verified in a click. Your reputation stays yours.

Signed webhooks

Sent, bounced, complained, opened, clicked and received events, signed with Standard Webhooks and retried for a day.

Inbound email

Receive replies and support mail at any address on your domain, delivered to your app as a webhook.

Address validation

Catch typos like gmial.com, disposable and role addresses, and domains that take no mail, before they bounce.

Templates and broadcasts

Hosted templates with variables, contacts, segments, topics and one-click unsubscribe for newsletters.

Live in four steps

From sign-up to your first delivered email.

Sign up

Create your account at app.trivsend.com.

Add your domain

Publish the DNS records we show you, then verify.

Create an API key

A sending-only key is all your app needs.

Send

Call POST /emails, or point any SMTP client at smtp.trivsend.com.

Already using Resend?
