metra opened a new issue #9939: URL: https://github.com/apache/airflow/issues/9939
**Description** Failing tasks can create a lot of email noise if you have both `email_on_failure` and `sla` enabled. **Use case / motivation** Outside of working hours, say 6pm through 10am, I can receive 16*2 email notifications. Every hour, one email for the failure and one email for the missed SLA. A few ideas: - Sending both the SLA miss and the failure email feels redundant. If a task is failing then it should be obvious that it's also missing its SLA. Perhaps skip the SLA email in this case? - The SLA miss emails are threaded because their subject lines are equivalent. However, the failure emails include the failure date and time, which breaks threading. Consider dropping the time and/or date from the failure email? **Related Issues** None that I could find. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
