Simple Contact Us form for static websites

Serverless Contact Us Form

Quickly deploy an endpoint to handle your contact us form on your static website. We don't want to have servers running just to handle our contact us form which rarely gets invoked. Oh, and we also need Captcha because we don't have time in our lives for spam.

You can get your reCAPTCHA secret here: https://www.google.com/recaptcha/admin#list
