html.contact

A hosted endpoint for plain HTML forms: point a form's action at your html.contact URL and submissions are emailed to verified recipients, stored in a dashboard, spam-screened, limited to your allowed domains and exportable as CSV.

A static or AI-generated site gets a working contact form without writing or hosting any server code.

For your agent

  • Use a native `<form action="https://html.contact/f/hc_pub_..." method="POST">` with a `name` on every input; only the public hc_pub_ key goes in frontend code, never an hc_live_ key; use `_replyto`, `subject` and an `_hc_hp_*` honeypot field, and multipart/form-data only when there is a file input. The hosted MCP server uses scoped OAuth.
  • Never put an hc_live_ private key in browser code, static files or public repos
  • Do not collect regulated or sensitive data (health, card numbers, SSNs, passwords, children's data)
  • Do not add _to/_from/_cc/_bcc routing fields; recipients are set in the dashboard
