Overview

The ResendErrorEmailIntegrationEvent is triggered by the Scheduler Service to initiate the retry mechanism for failed email deliveries. This event is published hourly with high priority to ensure prompt recovery of email delivery failures and maintain customer communication reliability.

Event Flow

1. Scheduler Service publishes the event hourly (cron: 0 * * * *) with high priority
2. Notification Service receives the event and processes it
3. System identifies failed email records in the outbox
4. Failed emails are retried with parallel processing (max 5 concurrent operations)
5. Results are logged for monitoring and further analysis
