[Question from the form] How to trigger email notifications

Can I trigger e-mail notifications for approvals when I have finished a new blog and want to post it?

At a high level, yes that should be possible to configure.

At a low level, it all depends on the apps being used and the defined project requirements.

Automation is all about the details, some of which may seem small, but can actually completely change the scope and nature of the project and possibilities.
