The Challenge
Existing WP-Cron infrastructure was missing jobs under high load. With campaigns triggering thousands of simultaneous tasks, the platform was unreliable and causing revenue loss through missed sends and incomplete workflows.
The Results
Scaled to 1M+ tasks/day. Job failure rate fell from 12% to <0.1%. Email deliverability improved to 99.2%. Engineering time spent debugging async tasks dropped by 85%.
