What is a Message Broker?
A
message broker is a middleware that enables different systems to communicate with one another by translating messages between formal messaging protocols. In the context of
email marketing, message brokers play an essential role in ensuring that emails are delivered promptly and efficiently, by managing the flow of messages between email applications and servers.
Scalability: It allows for handling a large volume of emails without overloading the email server.
Reliability: Ensures that messages are delivered even if some systems fail.
Flexibility: Provides a seamless way to manage different email formats and protocols.
Efficiency: Optimizes the email sending process by queuing emails and sending them in batches.
How Does a Message Broker Work?
A message broker works by receiving messages from a sender, processing them, and then routing them to the appropriate receiver. This involves several steps:
Message Reception: The broker receives an email message from the email marketing application.
Message Processing: The message is processed and transformed if necessary to match the protocol of the recipient system.
Message Routing: The broker routes the message to the appropriate email server for delivery.
