Wildbit launched Beanstalk in 2007, and it led to problems with missing emails and hassle in troubleshooting. To address these issues, Wildbit built Postmark, a platform that provides message history for 45 days, including basic info like events, text, HTML, and raw source of each message sent during this period. The message history starts with a statistics dashboard that gives customers a quick visual way to see recent activity. Customers can adjust the date range and view activity based on tags or individual messages and recipients. The platform also includes an activity stream that provides a rolling view of recent messages, segmenting by event type, tags, or date, as well as search capabilities by email address, tag, or subject line. Postmark stores bounces and spam complaints forever, and customers can use the Messages API to get sent messages for their own data store. The platform aims to take the guesswork out of knowing what happens to a message when it's fired off from an app.
