Make the form work.
No fluff. Each guide answers one real question up front, then shows the working code.
Start from what went wrong
These are for the problem, not the tool. A form that sends nothing, spam arriving hourly, an email that never lands: each guide starts there and works back to the cause.
Every one opens with a direct answer in the first paragraph, so you can leave immediately if that is all you needed. Then the working code, the mistakes that look correct but are not, and the specific errors you are likely to hit with the fix for each. The snippets are the same code the product is tested against, so nothing here drifts out of date independently of the thing it documents.

Send an HTML form to email without running a server
HTML can’t email a form on its own. To send an HTML contact form to email without PHP or a server, set the form action to an endpoint that receives the POST, filters spam, and emails you. Here’s the three-line version.
Read the guideBuild a contact form without a backend
Add a working contact form without a backend, a server, or a serverless function: point it at a form endpoint that receives submissions, filters spam, and emails you. Compare the options and copy a complete example.
Read the guide AI buildersConnect an AI-built form to email
AI website builders generate the form UI but not the backend. Paste one prompt to wire a Lovable, Bolt, v0, Cursor, or Replit form to a MakeTheForm endpoint, spam-filtered submissions by email and in an inbox.
Read the guide SpamStop contact form spam without punishing your visitors
Contact form spam is almost entirely automated. A honeypot field, a time-to-submit check, and server-side filtering prevent most of it without a reCAPTCHA puzzle. Here is the setup, and when an invisible challenge is worth adding.
Read the guide TroubleshootingYour contact form is not sending email. Here is why
A contact form that does not email you is usually one of five things: no backend at all, an unverified sender, a spam-foldered notification, a broken SMTP configuration, or a submission that never left the browser. Work through them in order.
Read the guide SpamThe honeypot field: spam protection nobody has to solve
A honeypot field is a hidden form input that people never see and bots always fill. Here is how a form honeypot works, the correct HTML and CSS for one, and the three mistakes that make it catch nothing or block real visitors.
Read the guide Static sitesAdd a contact form to a static site
A static website has no server to receive a form. Point a plain HTML form at a hosted endpoint and it works on GitHub Pages, Netlify, Vercel, Cloudflare Pages, S3 or any other static host: spam filtered, emailed, and stored.
