This is the absolute lightest contact form for WordPress. This plugin is designed for the fastest pagespeed. So, there is no CSS stylesheet, no extra files, and no overhead. And no spam. It uses Google reCAPTCHA v3 so as not to annoy your users with any extra step, while keeping your contact form spam-free.
If all you need is a simple contact form to take messages from site visitors, and fast page speed is your priority, this minimal plugin is for you.
Although this form is lightweight and simple, it blocks SPAM, and has both client-side and server-side validation. This is a solid and dependable contact form.
NOTE: To make use of the extra spam protection from Google reCAPTCHA v3, you must <a href="https://isabelcastillo.com/recaptcha-v3-keys" rel="nofollow ugc">get your reCAPTCHA v3 API keys</a> from Google. This is a free and easy step, and is strongly recommended.
