WP Mail SMTP is a WordPress plugin that helps you configure and send emails from your WordPress site using a reliable and secure SMTP server. It allows you to send email notifications, contact form submissions, and other types of emails from your WordPress site.

By default, WordPress uses PHP’s built-in mail function to send emails, which can cause issues with deliverability and spam filtering. WP Mail SMTP solves this problem by routing your WordPress emails through a trusted SMTP provider, ensuring that your emails are delivered reliably and securely.

When you install and activate WP Mail SMTP, it adds a new settings page to your WordPress dashboard where you can configure the plugin’s settings. You can enter your SMTP server details, including your server hostname, port number, and authentication credentials.

WP Mail SMTP works by:

Authenticating with your SMTP provider: By providing authentication details, WP Mail SMTP can connect to your SMTP server and send emails on your behalf.

Configuring email settings: WP Mail SMTP allows you to configure your email settings, including the “From” name and email address, reply-to address, and email encryption settings.

Debugging and testing: WP Mail SMTP provides a built-in email testing tool that allows you to send a test email to ensure that your SMTP server is working correctly.

WP Mail SMTP also provides additional features like:

Custom SMTP integrations: It offers custom integrations for popular email services like Gmail, Outlook, Yahoo Mail, and others.

Email logs: WP Mail SMTP stores a log of all emails sent from your WordPress site, allowing you to troubleshoot any issues and monitor your email activity.

Error notifications: It sends error notifications if there is a problem sending an email, allowing you to quickly identify and resolve any issues.

Overall, WP Mail SMTP is an essential plugin for any WordPress site that needs to send emails reliably and securely, ensuring that your emails reach their intended recipients and avoid being filtered as spam.
