Forms & validation

Build forms that validate the input automatically and neatly store every submission — from contact form to quiz.

With forms you let visitors get in touch, sign up or take a test. You choose the fields yourself, the input is validated automatically and every submission is stored neatly — so you never lose a request.

Automatic validation

Required fields, email addresses, web addresses and numbers are checked before the form can be sent. The visitor sees right at the field what is still missing, instead of a vague error afterwards. Spam is silently kept out through an invisible trap and a limit on the number of submissions.

More than a contact form

A form can also be a multi-step wizard (one question per step, with progress) or a real test with scores: every answer counts points and the visitor sees their outcome immediately. After a submission a confirmation email can go to the sender and a notification to you; anyone signing up for a newsletter joins the subscriber list with explicit consent — neatly in line with the GDPR.

Example

Enter an invalid email address below and click next to it — the check happens instantly. The full working form is on the contact page:
