February 2011 Summaries

Postmark's email delivery service was used by Readability to launch their new product, a full-fledged "Readability" bookmarklet experience. The team at Readability found Postmark invaluable in simplifying their large-scale emailing needs, allowing them to focus on other aspects of their business. By integrating with Postmark, Readability is able to forget about common email-related issues such as delivery confidence, spam marking, and bounced emails, making the service a valuable investment for the company.

The Postmark team has made significant changes to their API, which is now hosted on Amazon EC2, with the aim of improving stability, performance, and scalability. The new architecture provides a massively redundant system, allowing for failover, load balancing, and scalability. This change enables better handling of increasing email volumes, ensuring Postmark's continued availability and performance. The team has also introduced lightweight instances and used Dynect for DNS load balancing to minimize downtime and optimize performance. With the new tools, the team expects improved throughput and overall better performance, while continuing to build a robust architecture that handles failures at each level without downtime.
