šļø Overview
Transactional emails are automated messages sent to individuals based on specific actions or events they've triggered. Unlike marketing emails, which are promotional in nature and sent to a list of subscribers, transactional emails are tailored to an individual's interaction with a platform or service. They are often critical for the user experience and play a pivotal role in maintaining user trust and engagement.
šļø Example Transaction Flow
The following example illustrates the sequence of events when a user signs up for a service. After entering their details and clicking "Sign Up," the service saves this information in a database. Once stored, a welcome email is dispatched to the user. When the user clicks on this email to verify or activate their account, they receive a final account activation notification. Notably, since this email is directly linked to the user's action of signing up, it's termed a "transactional email."

In earlier times, sending a transactional email was straightforward. All you needed was a simple mail() function call from a PHP script, and voila, your email was dispatched. This function is straightforward, requiring just three inputs: the recipient's address, the subject, and the email content.
