The Postmark team has introduced an update to their Messages API, allowing developers to access detailed information about the delivery and status of email messages in one API call. The new feature includes a "MessageEvents" array that contains summaries of events such as delivery confirmations, open tracking events, and bounces, providing users with transparency into the life-cycle of the message. This update aims to give developers a fast way to follow up on support requests and reduce the time it takes to report on message delivery. The new API call returns a list of brief summaries of events, including the recipient's email address, type of event, received at timestamp, details about the event, and more. With this feature, developers can programmatically verify message delivery and get insights into the status of their emails in real-time, making it easier to troubleshoot issues and improve customer experience.
