In a previous post I had the opportunity to present the Entity Activity module which allows us to set up a notification system on any type of Drupal 8 content entity, according to the three main actions of their life cycle: creation, update and deletion. Since beta version 8, the Entity Activity module includes a sub-module, Entity Activity Mail, which now allows us to send by email a summary of the notifications generated for each user, according to a frequency that can be configured by each user. Let's discover this new feature.
