WordPress + Kawaa
Verify emails on your WordPress site
Add real-time email verification to your WordPress forms. Works with popular form plugins including Contact Form 7, WPForms, Gravity Forms, and Elementor Forms. Stop fake signups before they happen.
Kawaa app for WordPress coming soon
A dedicated Kawaa app is not yet published in the WordPress directory, so it cannot be connected from the dashboard yet. Today, call our REST API from your WordPress workflows — via a generic HTTP step such as Webhooks by Zapier or Make's HTTP module — using your Kawaa API key.
Features
How to Set Up
Get your API key
Sign up for Kawaa and get your API key from the dashboard.
Install the plugin
The plugin is not published to the WordPress.org directory yet — contact support for the package, then upload it under Plugins > Add New > Upload Plugin and save your API key in its settings. The plugin keeps the key on your server and proxies form checks through a WordPress REST route, so the key is never exposed to the browser.
Configure form validation
Enable verification on your forms by adding data attributes or configuring plugin settings.
Customize messages
Set custom error messages for invalid or risky email addresses.
Use Cases
Newsletter signup validation
Contact form spam prevention
User registration validation
WooCommerce checkout verification
Frequently Asked Questions
Which form plugins are supported?
The plugin hooks the common form plugins directly — Contact Form 7, WPForms, Gravity Forms, and Ninja Forms — and any other form can be checked by calling the plugin's WordPress REST route from your own code.
Does this slow down my forms?
Verification happens asynchronously, so the impact depends on your form configuration and the response path for that email.
Can I validate emails on WooCommerce checkout?
Yes, add validation to the billing email field to prevent orders with invalid emails.
