### Description The default Airflow task failure email is difficult to read and not optimized for operators. Currently the subject and body contain a raw Python object dump (UUIDs, repr(), internal fields), which makes it hard to quickly understand: - which DAG failed - which task failed - when it failed - where to click for logs <img width="1196" height="581" alt="Image" src="https://github.com/user-attachments/assets/827493f3-a812-4b0d-910f-10a1a64b13b4"; /> This is noisy and not human-friendly for production operations. # What is proposed <img width="1194" height="966" alt="Image" src="https://github.com/user-attachments/assets/b6e77ff8-cb17-4565-bbf5-cc68e4786196"; /> Replace the current default task failure email with a cleaner, human-readable template. Instead of exposing a raw Python object dump (UUIDs, internal fields, repr()), the email should present structured, actionable information: DAG, task, run ID, attempt, timestamps, host, and a direct link to logs. Provide a simple, modern HTML + text layout optimized for quick scanning and mobile readability, while keeping advanced/debug details optional. This change improves the out-of-the-box operator experience without requiring users to create custom templates, and remains fully backward compatible since templates can still be overridden. I’ve attached the template files I created. Feel free to reuse or adapt them if helpful. ### Use case/motivation In real deployments: - alerts are read quickly on mobile - operators need key info at a glance - long debug metadata is rarely useful in email - links to logs are more important than internal fields Today this requires fully custom templates to get a usable format. A better default template would improve UX out-of-the-box and reduce customization overhead. ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
