Raw contact form (no CSS)

Nine lines, no stylesheet, nothing to override. Copy this into a page that already has its own form styles and it inherits them. It is also the shortest honest answer to "how much code is the integration". Everything else on this page is decoration around these fields.

HTML

Replace YOUR_ACCESS_KEY with the access key from your dashboard. Create one free. The endpoint and the honeypot are already in place.

Your form works in about a minute.
