ExploreAdd a WordPress contact form in three steps.

- Configure your website origin and thank-you destination, then test the published page.
Check whether this fits your WordPress site.
This approach suits a simple contact or enquiry form when you are comfortable editing HTML and want to manage messages outside WordPress. A native form plugin may suit you better if you need a visual editor inside WordPress, WordPress user workflows or an existing plugin’s conditional fields.
Self-hosted WordPress must allow your account to save form markup. WordPress.com restricts form and input tags to supported plugin-enabled sites with hosting features activated. Check the WordPress.com code requirements before starting.
Frequently asked questions
Contact form
questions.
Does this work with Gutenberg?
Yes, through a Custom HTML block in the WordPress block editor, provided your account and hosting allow form markup. Use Custom HTML rather than a Code block, which displays the markup as text.
Does Form Koi connect to Contact Form 7, WPForms or Elementor Forms?
This guide creates a separate HTML form. It does not connect those plugins’ submission handlers or import their entries. Keep an existing plugin if you depend on its fields or WordPress workflows.
Do I need JavaScript?
The basic example submits with a native browser POST and needs no JavaScript. Turnstile protection requires its widget script; inline success and error messages also require JavaScript.
Will this fix all WordPress email?
No. Form Koi handles notifications for forms connected to its endpoint. Password resets, store emails and other WordPress notifications keep using their existing delivery setup.
