The Postmark team has released several updates and improvements to their product, including a new API Explorer that allows users to test the Postmark API without running cURL commands. The team has also worked on performance and scaling improvements, adding more instrumentation to monitor performance issues and making changes to improve the performance of their RabbitMQ cluster. Additionally, they have released a new status page with improved incident types and reporting, as well as addressing several bug fixes, including errors in the Spamcheck API and transient events showing as delivered in the API. The team is also planning to release several new features, including domain verification, permissions, link tracking, and 2-Factor Authentication, which were requested by customers and are expected to be released in the second half of the year.
