<p><strong>Sparrow Email OTP Verification for Contact Form 7</strong> provides a robust security layer for your website by verifying user email addresses before form submission. This effectively blocks bots, spammers, and malicious actors from flooding your inbox with fake data or invalid leads.</p>
<h3>Why this plugin is different:</h3>
<p>Most existing OTP plugins require you to pay for their proprietary API or use their specific SMTP service to send codes. This often leads to unexpected monthly costs and vendor lock-in.</p>
<p>This plugin is built with a <strong>“Your Server, Your Rules”</strong> philosophy. It sends OTP codes using the native <code>wp_mail()</code> function, meaning it utilizes your website’s default mail configuration or your preferred SMTP service. <strong>There are no extra costs, no hidden fees, and no third-party accounts required.</strong></p>
<h3>Features</h3>
<ul>
<li><strong>Block Bots & Spam:</strong> Ensure every submission comes from a person with a valid, accessible email address.</li>
<li><strong>Conditional Display (New v1.1.0):</strong> Dynamically hide verification elements inside an elegant wrapper box until an email string is typed.</li>
<li><strong>Cost-Effective:</strong> Zero cost to send OTPs—it uses your existing server or SMTP setup.</li>
<li><strong>Privacy First:</strong> No data is sent to external verification APIs; everything stays on your server.</li>
<li><strong>Smart Detection:</strong> Automatically finds the email field in your Contact Form 7 forms.</li>
<li><strong>Security-First Rate Limiting:</strong> Built-in protection to prevent OTP request abuse by limiting users to 3 attempts per 5 minutes per IP address.</li>
<li><strong>Lightweight:</strong> Minimal footprint to ensure your site remains fast and passes Core Web Vitals.</li>
</ul>

User Verification by PickPlugins


There was an error after I opened the plugin. It started well, but I don't know what I configured to cause the problem.



[18-Feb-2025 08:44:58 UTC] PHP Warning: Trying to access array offset on value of type null in /data/wwwroot/wordpress/wp-content/plugins/post-smtp/Postman/PostmanEmailLogs.php on line 724


Trying to access array offset on value of type null


I am writing to support for the second time. The WooCommerce section is not working! Settings are not being saved. Could you at least respond and explain why? Is it a paid feature or a bug on your side?
