Overview

Formpost is a free contact form to email API that allows you to point any HTML form directly to a dedicated endpoint, with submissions delivered straight to your email inbox. It eliminates the need for a backend server or custom code to process form data, making it ideal for static sites and Jamstack architectures. The service includes AI-powered spam filtering using LLMs to understand intent and catch sophisticated spam beyond traditional rules. Submissions are stored securely in the cloud and can be managed via a dashboard, with options for file attachments uploaded directly to Amazon S3, webhooks for forwarding data to other services, and an autoresponder feature. All data is encrypted in transit and at rest, and you retain full control with export and deletion capabilities. Formpost works with any tech stack—HTML, React, Vue, and no-code platforms like Webflow and Framer—without injecting any external styles or scripts into your pages.
