The default <code>wp_mail()</code> function in WordPress can often be unreliable. Many hosting providers limit or poorly configure email sending, which leads to important notifications (like registrations, password resets, or WooCommerce orders) ending up in spam or not being delivered at all.
Cherkasov SMTP Mailer solves this problem by re-routing all your site’s outgoing emails through a professional SMTP server (such as Gmail, SendGrid, or any other mail service). This significantly increases the reliability and deliverability of your emails.
The plugin features a modern, intuitive interface, an advanced email log, and the ability to receive instant notifications about sending statuses in your Telegram.
<h3>Features</h3>
<ul>
<li>Reliable Delivery: Send emails through any SMTP server to avoid spam filters.</li>
<li>Easy Configuration: Quick presets for popular services (Gmail, Outlook, SendGrid) and flexible options for any other SMTP provider.</li>
<li>Email Log: Keeps a detailed log of all sent emails. View content, status, headers, and error messages.</li>
<li>Log Management: Search for emails, resend failed messages (one by one or all at once), and delete entries.</li>
<li>Telegram Notifications: Get instant messages in Telegram about successfully sent or failed emails.</li>
<li>Testing Tool: A built-in feature to send a test email to verify your settings and see a detailed debug log.</li>
<li>Security: Passwords and tokens are not displayed in the form after being saved and are transmitted securely.</li>
<li>Modern UI: A clean, responsive, and user-friendly interface built with modern web technologies.</li>
<li>Retention Policies: Configure automatic deletion of old log entries to keep your database clean.</li>
</ul>
