The activity submodule can attach a report to any entity with an email field, which will show email activity for that specific address over the last 7 days.
The reports submodule provides a Dashboard and Account Summary to the Admin > Reports section of Drupal. This allows admins to see volume, open and click rates, and more account stats right from Drupal.
The template submodule allows you to use Mailchimp Templates to style your emails, including configuring per-template keys to link them with specific modules or needs within Drupal. Currently, only a single template area can be populated with Drupal-generated content.
