<h4>Features</h4>

<li>Multiple responder emails, send a HTML formatted mail in response to the form submission</li>
<li>Works with the default wp_mail() function (use it together with the <a href="https://wordpress.org/plugins/simple-smtp-by-maileroo/" rel="ugc">Maileroo</a> plugin to send emails via SMTP)</li>
<li>Optional: Protect your forms by blocking specific countries which are not relevant for your website or business</li>

<p>The plugin is built to keep stuff simple. If you need a complex web form or if you need a form builder, please use one of the form plugins you can find in the WordPress repository. To use the “Block countries” feature we use the IP to Country API from Country.is. They offer a free service and you don’t need an API key.</p>

<p><strong>Honeypot Guard</strong> is a powerful, privacy-focused anti-spam solution that protects your WordPress forms without annoying your visitors with CAPTCHAs. Using invisible detection techniques, it blocks spam bots while maintaining a seamless user experience.</p>
<h4>Why Choose Honeypot Guard?</h4>
<p>Unlike CAPTCHA-based solutions that frustrate users and hurt conversions (studies show CAPTCHAs reduce form submissions by 10-40%), Honeypot Guard provides <strong>superior spam protection</strong> with <strong>zero user friction</strong>.</p>

<li><strong>Timestamp Validation</strong> – Detects instant submissions (bots can’t read like humans)</li>
<li><strong>Intelligent Gibberish Detection</strong> – Catches keyboard mashing and random text patterns</li>
<li><strong>Advanced Heuristic Analysis</strong> – Pattern-based detection of common spam characteristics</li>
<li><strong>Character Script Filtering</strong> – Optionally block submissions containing specific character scripts (Cyrillic, Chinese, etc.)</li>
