MuxForms on WordPress is a Custom HTML block with your form div and embed.js—no Contact Form 7 or PHP mail. Allow the WordPress site URL on the form so browser submissions pass CORS, then read leads in the same inbox as your other sites.

Paste a Custom HTML block. Allow https://your-wordpress-site.com. Submissions appear next to every other MuxForms property.
WordPress setup
| Step | Detail |

| Origin | https://your-wp-site.com |
| Inbox | Shared with non-WP forms |
Custom HTML block
Avoid another plugin that emails the admin account and dies on host changes. MuxForms stores the payload in Postgres and can email a verified domain.
<div data-form-id="FORM_UUID"></div> <script src="https://www.muxforms.com/embed.js" defer></script>
Full-site editor
In block themes, add the same snippet to a Custom HTML block on your Contact template. Clear any page cache plugin after publishing.
Common questions
- Do I need a plugin?
- No plugin is required—only the embed snippet and an allowed origin.
- Will PHP mail matter?
- No. MuxForms stores submissions and emails via its own sending domain.
- Can I style the form?
- Use form appearance settings in MuxForms; theme CSS wraps the block.
- What if I change hosts?
- Update the allowlist origin if the public URL changes.
One script. No plugin debt.
Use the same form backend as your Next.js sites and Expo apps.
