Collect form submissions online without a backend — spam free

Ready-to-use form backend for your HTML or JS forms.

POST your forms to us, real submissions go to your inbox.

No signup required for small sites, see pricing.

<form action="https://api.postcatch.io/submit/<GENERATED_KEY>" method="POST">
  <input type="hidden" name="_next" value="/thank-you" />
  <input type="email" name="email" />
  <input type="text" name="message" />
  <button type="submit">Submit</button>
</form>

Focus on user experience, we'll handle the rest.

PostCatch is explicitly built for developers. We don't impose any styling or branding on your forms. You keep full control over that, we'll do the boring part.

Dead simple installation

Copy-paste the URL in your form's action or in your POST request and you're good to go. No captcha or honeypot needed.

Built-in spam detection

We do request analysis to block out most bots, followed by content filtering using a text classification model to prevent spam on your forms. Focus on styling and sleep tight at night.

Reliable delivery

We handle all the hardships of sending emails reliably for you. SPF, DKIM or MX records? Forget about it. Start receiving emails now.

Universal solution

Wether you're building a complex, interactive form in JS, or just doing good old HTML in any server-side language, PostCatch is ready to go.

Perfect for static sites

Ideal for situations where you don't have a server and just need to send emails from the front-end.
