Capabilities

Everything a form needs, none of it self-hosted.

Postbox Forms handles the parts you don't want to build twice: spam, storage, notifications, and where the data goes next.

01

Zero backend required

Point your form's action at a Postbox Forms endpoint. That's the entire integration.

02

Spam filtering, built in

Honeypots and rate limiting on every plan. Add AI-based review to catch bot-written submissions your rules would miss.

03

Instant notifications

Get emailed the moment a submission comes in, formatted and readable — not a raw data dump.

04

Nothing gets trapped

Every submission is stored and exportable to CSV, on every plan, including free.

05

File uploads included

Resumes, images, attachments — accepted and stored without extra configuration.

06

Forward it anywhere

Send new submissions to Slack, a webhook, or your CRM as they arrive.

How it works

Three lines of HTML. That's the setup.

No SDK, no npm install, no API client. Point a standard form tag at your endpoint and Postbox Forms takes it from there.
