RabbitMQ uses a system of producers, queues, and consumers to manage message flow. In the context of email marketing:
Producers: These are the components that generate email messages. For example, a user action like signing up for a newsletter can trigger the creation of an email message. Queues: Messages are stored in queues until they are processed. This ensures that no email is lost even if the system is temporarily down. Consumers: These are the components that process and send the emails. They retrieve messages from the queues and deliver them to the recipients.
