Send Email Notification to shared email address

Hi everyone,

i am new here and I hope this is the right place for my question.

I have shared a folder via email. Everything works as expected, but can I send email notifications to this email address if, for example, a file has been created or modified?

Background: I use Nextcloud to exchange files with my customers. But I don’t always want to inform them myself if a file has been added or changed in their shared folder.

Is there a way to solve this?

I use Nextcloud 18.0.3 on an Apache web server with php 7
