<p><strong>Common Issues:</strong></p>
<ul class="list-disc list-inside space-y-1 ml-4">
<li>XAMPP/Local development: PHP mail() function often doesn't work without SMTP configuration</li>
<li>Gmail SMTP: Use App Passwords instead of regular passwords</li>
<li>Firewall: Check if port 587 (TLS) or 465 (SSL) is blocked</li>
<li>Email settings: Verify SMTP host, port, username, and password are correct</li>
<li>Template issues: Ensure email template is active and properly formatted</li>
</ul>
<p class="mt-4"><strong>Recommended Solutions:</strong></p>
<ul class="list-disc list-inside space-y-1 ml-4">
<li>Install PHPMailer for better SMTP support</li>
<li>Use a reliable SMTP service (Gmail, SendGrid, Mailgun)</li>
<li>Test with a simple email service first</li>
<li>Check server error logs for detailed error messages</li>
