Hi Ivana,
If you're open to paid solutions, SPACE provides built-in functionality for sending emails directly from TI processes, supporting richly formatted emails and file attachments, eliminating the need for custom scripting.
Additionally, SPACE jobs allow you to schedule TI processes and Python scripts with a flexible cron format and include built-in email notifications.
Finally, if you transition to TM1 V12 in the future, you will only need to modify a single SPACE process.
Let me know if you'd like more details!
