Postmark has introduced a new status page where they publicly share their inbox rates and delivery times across major ISPs, including Gmail, Yahoo, Outlook, iCloud, and AOL. The company aims to increase transparency by sharing this data with customers, who can expect great deliverability regardless of the volume or pricing plan. Postmark recognizes that email delivery speed is critical, especially for infrastructure products like email, and has created a new metric called "Time to Inbox" to measure this speed. By sharing their approach and tools used to gather this information, Postmark aims to help the industry move towards increased transparency and better decision-making for customers. The company's goal is to be the fastest and most reliable email service provider in the world, and the new status page represents a step towards achieving this goal by providing customers with more information about their deliverability performance.
