Mail Queue is a free WordPress plugin designed to bolster the security of your website by managing email submissions effectively. It intercepts the standard wp_mail() function, placing outgoing emails into a queue for better control and monitoring. This feature is particularly useful in identifying and mitigating unusual activities, such as spam bots targeting your contact forms. Users can set parameters for the frequency and volume of email dispatches, ensuring that their site remains secure and operational.

In addition to its email management capabilities, Mail Queue offers comprehensive logging of all email submissions, providing transparency and accountability. Users receive alerts when the email queue reaches a critical level or if WordPress encounters issues while attempting to send emails. This proactive approach to email management makes Mail Queue an essential tool for any WordPress site looking to enhance its communication security.
