This morning, Postmark experienced a delay in sending outbound emails to all customers starting at 5:15am. The issue was resolved by 8:43am when the queues were cleared and sending resumed normally. Postmark takes issues like this seriously and is committed to delivering on its core features of availability and speed. To prevent similar delays, Postmark plans to review alerting workflows, address the root cause of delays, automate capacity better, and improve its status page to provide clearer information about email queueing and processing times.
