Happyforms – Form Builder for WordPress: Drag & Drop Contact Forms, Surveys, Payments & Multipurpose Forms

Best WordPress contact form, newsletter form and payment form builder without the sucky stuff — lost emails, pesky spam, leaky privacy and outsourced  …

<p>Duplicate Killer – Block Duplicate Form Submissions in WordPress.</p>
<h3>WooCommerce – Prevent Accidental Duplicate Orders</h3>
<p>Duplicate Killer also protects WooCommerce Classic Checkout from accidental duplicate orders.</p>
<p>WooCommerce already disables the “Place order” button, but duplicate orders can still happen when:</p>
<ul>
<li>Checkout is slow</li>
<li>Payment gateways lag or retry</li>
<li>Customers refresh the page</li>
<li>Multiple tabs are used</li>
<li>Network requests are retried</li>
</ul>
<p>Duplicate Killer FREE adds lightweight server-side duplicate protection for WooCommerce Classic Checkout.</p>
<p>If the same customer attempts to submit an identical order within 60 seconds, the duplicate is blocked and a validation message is shown.<br />
!!! No changes to your checkout design. No impact on performance. No additional configuration required.</p>
<p>If your forms receive the same email address multiple times, fake leads, or repeated submissions, this plugin blocks them instantly.</p>
<p>Choose which fields must be unique (email, phone, text) and block duplicate entries automatically — without changing your form design or user experience.</p>
<p>Duplicate Killer works silently in the background and integrates seamlessly with popular WordPress form plugins and page builders.</p>
<h3>Cross-Form Duplicate Protection (PRO)</h3>
<p>Duplicate Killer PRO introduces Cross-Form Duplicate Protection.</p>
<p>This feature allows duplicate detection across multiple forms on your website.</p>
<p>For example, if a user submits the same email address in two different forms, Duplicate Killer PRO can detect the duplicate and block the second submission.</p>
<p>This is useful when:<br />
– multiple contact forms exist across different pages<br />
– marketing forms collect the same email address<br />
– lead capture forms should only allow one submission per user<br />
– different form plugins are used on the same site</p>
<p>This feature is available in Duplicate Killer PRO.</p>
<p>Free: In the free version, duplicate protection can be enabled for one form per supported plugin.</p>
<p>PRO: Duplicate Killer PRO enables multi-form protection with individual rules and messages per form.</p>
<h3>Supported Plugins</h3>

</ul>
<p>WooCommerce PRO adds:<br />
– Checkout Blocks (Store API) support<br />
– Configurable lock window (30–300 seconds)<br />
– Advanced fingerprint controls (phone, shipping, IP, customer ID)<br />
– Order linking (direct link to matching WooCommerce order)<br />
– Gateway breakdown (Stripe, PayPal, COD, etc.)<br />
– Trends dashboard (Last 24h, 7 days, 14 days)<br />
– CSV export for audits and support teams<br />
– Detailed analytics (top products, domains, checkout types, IPs)<br />
– Designed for real-world edge cases such as slow hosting, gateway retries, reverse proxies and unstable mobile networks.</p>
<h3>When to use Duplicate Killer</h3>
<p>Use this plugin if you receive repeated submissions with the same email, phone number or text values.<br />
If you only need basic spam protection, a CAPTCHA plugin may be enough.</p>
<h3>When should I use Duplicate Killer PRO?</h3>
<p>Use the PRO version if your site has multiple forms with different purposes — for example a contact form, a registration form and a newsletter signup — and each one needs different duplicate submission rules.</p>
<h4>Does FREE support WooCommerce Checkout Blocks?</h4>
<p>No. Checkout Blocks use a different system (Store API) and require the PRO version.</p>
<h4>What happens if I upgrade to PRO later?</h4>
<p>All WooCommerce duplicate logs stored in the FREE version are automatically used by PRO analytics. No database migration is required.</p>
<h4>Does this prevent payment gateway retries?</h4>
<p>FREE prevents accidental duplicate submissions on Classic Checkout.<br />
PRO adds enhanced idempotency handling and deeper gateway analytics.</p>
