A WordPress SMTP (Simple Mail Transfer Protocol) plugin is a tool that allows you to configure the email settings for your WordPress website and send emails using an SMTP server. By default, WordPress uses the PHP mail function to send emails, but it has some limitations and can often result in delivery issues or emails being marked as spam.
SMTP plugins provide a more reliable and efficient way to send emails from your WordPress site. They enable you to connect your website to an external SMTP server, which is specifically designed for sending emails. This SMTP server can be provided by your hosting provider, an email service provider, or a dedicated SMTP service.
When you install and configure an SMTP plugin, you typically need to provide the SMTP server details, such as the server address, port number, username, password, and encryption method. Once the plugin is set up, all outgoing emails from your WordPress site will be routed through the configured SMTP server, ensuring better deliverability and reducing the chances of emails being flagged as spam.
SMTP plugins often provide additional features, such as email logging, email throttling, email templates, and debugging tools, which can help you troubleshoot any email-related issues and track the delivery status of your emails. SMTP plugin can improve the reliability of your WordPress site’s email notifications, contact forms, password reset emails, and other email-related functionalities.
