Bad addresses stop on their own

Bounces and spam reports take an address off your list, so your sending record stays clean.

Try it before you code

Send a real email from the dashboard, then copy the code into your app.

Acme <hello@acme.com>
To

Subject

For developers

Your first email is a few lines away

Connect your app with one request. Offsend handles the rest.

  • Try a send from the dashboard before you write any code
  • Works from any language, with a TypeScript SDK if you want one
  • Already on Resend? Most apps switch by changing one setting
import { Offsend } from "@offsend/sdk";

const offsend = new Offsend("os_123456789");

await offsend.emails.send({
  from: "hello@mail.acme.com",
  to: "maya@example.com",
  subject: "Your receipt",
  html: "<p>Thanks for your order.</p>",
});

FAQ

Questions, answered

Who is Offsend for?

Anyone sending email from their product: receipts, sign-in links, password resets, alerts and updates.

Do I need my own domain?

Yes. You send from addresses at your own domain, which is what inbox providers trust, and what your customers expect to see.

Can I switch from Resend?

Yes. Offsend accepts the same requests as Resend, so most apps only need to change where they send them.

How much can I send?

New accounts start at 100 emails a day, and the limit goes up as you build a good sending record.

Can I receive email as well?

Yes. Point your domain’s mail at Offsend, and messages sent to your addresses show up in the dashboard’s inbox.
