About Web3Forms

Web3Forms is a form-to-email service for websites. You verify your email address to get an access key, put it in a hidden field of a plain HTML form that posts to the Web3Forms endpoint, and each submission arrives in your inbox. No server, PHP or other backend code is needed, and it works with any front end, with examples for HTML, JavaScript and React. Because it is an API, the form can keep any custom design.

Spam protection includes a honeypot checkbox field, and a hidden redirect field can send visitors to a custom confirmation page. Submissions are sent over HTTPS, encrypted at rest and stored for up to three years, with a retention period you control. The service runs on AWS infrastructure and describes itself as GDPR compliant, saying it does not share or sell data. A library of form templates and documentation is available. The free plan allows 250 submissions per month with no credit card, and the pricing page covers paid options.
