Email queuing

**Email queuing**

Email queuing is a process that allows outgoing emails to be temporarily stored and managed in a queue before being sent out. This helps improve the performance and reliability of email delivery by controlling the flow of messages, preventing server overload, and ensuring that emails are sent in a timely manner. Implementing email queuing is especially useful for websites and applications that handle large volumes of emails, such as newsletters, notifications, or transactional messages.
