About Formpost

Formpost is a contact-form-to-email API that lets you point any HTML form at a single endpoint so every submission lands in your inbox — no server or backend code required. It includes LLM-based spam filtering, reliable email deliverability, encrypted transport and at-rest storage, and a searchable dashboard for submissions. Submissions are stored for configurable retention (30 days on Free, 1 year on Pro, indefinite on Business). It's a lightweight Go service and a pure API (no widget or iframe), so you keep full control of your markup and styling.

Key Features

One endpoint API — point any HTML form to submit without backend code
AI/LLM spam filtering for higher-quality submissions
Searchable, exportable dashboard with configurable retention
Encrypted in transit and at rest; endpoint bound to configured recipient email
No iframe or injected styles — use your own markup and CSS

Who is this for?

Web developers and site owners who need a simple, secure contact form backend without running servers
