What is FormEmailAPI?
FormEmailAPI (formerly Formpost) is a contact form-to-email API designed for websites that do not have their own backend. Its fundamental purpose is to receive submissions sent through HTML forms and deliver them directly to the user's email inbox, completely eliminating the need to manage servers, configure databases, or write server-side code.
How it works
FormEmailAPI's core technology is built on a lightweight service developed in Go, optimized for asynchronous request processing. This ensures that visitors do not experience unnecessary delays while integrations or email deliveries are being processed. For security and storage, the platform leverages Amazon S3 infrastructure and managed databases in AWS regions, ensuring that attachments and data are maintained under professional standards for availability and end-to-end encryption.
The most innovative aspect of the tool is its AI-powered spam filtering. Unlike traditional methods based on fixed rules, it uses Large Language Models (LLMs) to understand message intent and detect spam that other systems might miss. This artificial intelligence layer is complemented by additional protections such as honeypots, support for reCAPTCHA, hCaptcha, and Turnstile, as well as a domain blocking system that prevents fraudulent use of the form on unauthorized sites.
Operation is straightforward and requires no complex installations or invasive scripts. The user generates a unique endpoint in the dashboard and inserts it into the action attribute of their HTML form. Since it is an API and not a closed widget, it offers total freedom for custom styling via CSS, without relying on iframes that could slow down loading on the visitor's computer or mobile device.
Key features
Key features and practical benefits include:
- Secure Storage: Data is stored encrypted and is accessible for searching or exporting in JSON and CSV formats.
- Webhook Integrations: Allows submissions to be automatically redirected to Slack, Discord, or Telegram channels.
- File Management: Supports attachment uploads that are stored and served directly from the cloud.
- Autoresponders: Facilitates sending personalized, automatic confirmations to senders immediately.
- Submissions API: Features a read-only REST endpoint to integrate collected information into dashboards or external tools.
Who it's for
FormEmailAPI is ideal for web development agencies, static site creators, and marketing teams looking for an efficient, maintenance-free lead capture solution. It is compatible with any tech stack, from pure HTML to modern frameworks like React, Next.js, or Vue, providing a reliable infrastructure for contact forms, job applications, or satisfaction surveys.
