The Postmark team has been working on improving the performance and stability of their email service, aiming to deliver all emails to inboxes within 10 seconds or less. They have made significant improvements to their systems, including increasing Elasticsearch capacity, upgrading RabbitMQ cluster to v3, and moving SMTP services to Packet.net data centers. Additionally, they published two new guides on transactional email best practices and using Gmail Inbox Actions. The team has also fixed 18 bugs in July and August, with a focus on ongoing bug fixing and customer support. Looking ahead, the Postmark team is preparing to launch link tracking and domain verification features, which will allow users to verify entire domains for sending.
