<h3>🚀 Want More? Upgrade to CF7 Captcha Pro</h3>
<p>This free version gives you solid CAPTCHA protection. But the smartest bots are already solving CAPTCHAs.</p>
<p><strong>CF7 Captcha Pro</strong> adds six extra layers of invisible spam defense on top of what you already have here, plus a full set of tools to capture and act on every lead your forms collect.</p>
<h3>What you get with Pro</h3>
<p><strong>6-Layer Spam Defense</strong> — stops 99.9% of spam without ever bothering your visitors:<br />
– <strong>Advanced Honeypot</strong> — invisible trap fields with names that regenerate every 24 hours.<br />
– <strong>Time Limit Validation</strong> — bots submit in 0.2 seconds. Humans take 15–30. This blocks anything that moves too fast (or stays too long).<br />
– <strong>Rate Limiting</strong> — caps submissions per IP so bot networks can’t flood your inbox or burn through your email quota.<br />
– <strong>Geographic Blocking</strong> — whitelist only the countries you serve, or blacklist known spam regions.<br />
– <strong>IP Pattern Blocking</strong> — block single IPs, wildcards, CIDR ranges, or entire subnets when you know exactly where an attack is coming from.<br />
– <strong>Word Filter</strong> — scans every submission for spam keywords, phishing URLs, and known scam phrases before it reaches you.</p>
<p><strong>Lead Recovery</strong> — 70% of people who start filling out a form never submit it. Pro captures their data in real-time as they type, so you can follow up on leads that would otherwise vanish.</p>
<p><strong>Database Storage & Export</strong> — every submission is saved with full metadata (IP, browser, referrer, timestamp). Export to CSV, Excel, JSON, or PDF whenever you need it. No more lost leads if your email fails.</p>
<p><strong>Webhooks</strong> — send form data instantly to any URL. Connect to Zapier, Salesforce, Slack, Google Sheets, or any custom API. Multiple webhooks per form, with retry logic built in.</p>
<p><strong>Mailchimp Integration</strong> — submissions automatically added to your Mailchimp lists. Field mapping, tags, opt-in handling.</p>
<p><strong>Twilio SMS</strong> — receive instant alerts for every submission or send automated SMS replies to your clients.</p>
<p><strong>Comprehensive Logging</strong> — every spam block, webhook call, and integration event is logged. Debug any issue in minutes instead of hours.</p>
