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.

Configure SMTP mailing in WordPress, including support for sending email via SSL/TLS (such as Gmail).
This plugin is the official successor to the original SMTP plugin for WordPress (wpPHPMailer).
Use this plugin to customize the SMTP mailing system used by default by WordPress to handle outgoing emails. It offers you the ability to specify:
<ul>
<li>SMTP host name</li>
<li>SMTP port number</li>
<li>If SMTPAuth (authentication) should be used</li>
<li>SMTP username</li>
<li>SMTP password</li>
<li>If the SMTP connection needs to occur over ssl or tls</li>
</ul>
In addition, you can instead indicate that you wish to use Gmail to handle outgoing email, in which case the above settings are automatically configured to values appropriate for Gmail, though you’ll need to specify your Gmail email address (including the “@gmail.com”) and password.
Regardless of whether SMTP is enabled, the plugin provides you the ability to define the name and email of the ‘From:’ field for all outgoing emails.
A simple test button is also available that allows you to send a test email to yourself to check if sending email has been properly configured for your site.
