Is there a way to notify me by email when a service is interrupted?

yes, here's the steps:

1. go to settings menu
2. go to alarm section
3. go to alarm setting section in the alarm section
4. you can modify the email and add the email configuration. if you wish to use your own smtp server in your same aapanel mail server then you can fill the form, that's same if you want to use yahoo or gmail or etc. but i believe gmail or yahoo have their security method such as app password, etc.
5. after add your email, go to alarm list section, then you can add task -> task type -> service stop alert -> then you can choose nginx, or mysql, or php-fpm, etc. remember you just can add 1 alarm per task. for example if you wish to add mysql and nginx stop service, you must create 2 task, 1 for nginx and 1 for mysql.
6. after finished, you can try to stop your nginx manually and see if you received the alarm email.

it's same logic with apache, etc.
