Formpost Product Information
What is Formpost ?
Formpost is a form endpoint service built for websites that have no backend. Users point an existing HTML form at a unique Formpost URL, and submissions are delivered to a designated email inbox while also being stored in a searchable, exportable dashboard. The service requires no server, no backend code, and no widgets or iframes, so the form's markup and styling remain entirely under the site owner's control. Formpost works with any stack, including plain HTML, React, Next.js, Vue, Svelte, Astro, WordPress, and static hosts such as Vercel, Netlify, and GitHub Pages. Submissions are encrypted in transit and at rest, file attachments are stored on Amazon S3, and spam is filtered through honeypots, captcha services, keyword rules, domain locking, and an AI review layer that catches spam traditional rules miss.
Formpost's Core Features
Form endpoint that delivers HTML form submissions directly to email with no backend code or server required
AI review layer that uses LLMs to catch spam submissions that rule-based filters miss

Autoresponder emails with submitted fields merged into the reply
