Emails that actually land.

A tiny sandbox for building, previewing and sending transactional email. No vendor lock-in, no dashboards to learn.

Everything you need. Nothing you don’t.

Write once

Compose templates in plain React. Variables, partials and dark-mode safe styles out of the box.

Preview everywhere

See how a message renders in every major client before a single real inbox gets it.

Send with confidence

Rate limits, honeypots and header-injection guards are built in, not bolted on.

Up and running in three steps

  1. 01

    Connect SMTP

    Point Playground at any SMTP server. Gmail app passwords work fine.

    Drop in a form

    Contact and sign-up endpoints are ready to post to from any page.

  3. 03

    Ship it

    Deploy to Vercel and every submission lands in your inbox in seconds.
