What Formpost is
Formpost is a contact form backend that works as an API. You create a form, get a unique endpoint URL, and point your HTML form's action at it; submissions then arrive directly in your email. No server or backend code is required, which makes it a fit for static sites and JAMstack applications. Spam defense combines AI filtering that reads user intent with honeypots, Turnstile, hCaptcha, reCAPTCHA, keyword rules, and domain locking. Frameworks such as HTML, React, Next.js, and Vue are supported, attachments can upload to Amazon S3, auto-replies confirm receipt, and webhooks forward each submission as JSON to endpoints or chat apps like Slack, Discord, and Telegram.
What you can do with it
- Create a form and point an existing HTML form at its endpoint.
- Receive submissions by email and keep them searchable and exportable on the dashboard.
- Filter spam with AI plus captcha and rule layers.
- Accept file uploads that land in Amazon S3.
- Send auto-replies and forward submissions to Slack, Discord, Telegram, or your own endpoint.
Who it is for
- Developers who want form handling without standing up a backend.
- Website owners who need a contact form on a static site.
- Marketers capturing inquiries from landing pages and campaigns.
What to watch out for
The free plan retains submission data for 30 days, so anything you need long-term should be exported or moved to a paid plan. Unlike hosted form builders, Formpost provides no widgets, iframes, or injected styles, which means you write your own markup and CSS and keep control of the design. AI spam filtering reduces junk but will not eliminate it, so keep the captcha and rule layers switched on for public forms. Confirm the data storage region and privacy terms before collecting sensitive personal information through a form.
