As an email marketing executive, I want to be able to easily see how well emails are performing against other emails/journeys, so that I can make changes where appropriate.

If I want to compare a number of different emails and how they have performed (clicks/open), against each other, this is not easily possible as there's no list view.  For example, I have two journeys with 5 emails in each.  They are a similar type of journey so I'm interested to see the key open rates/clicks, etc.  Unless I go into each one, not possible with more than a handfull of emails, I can't see what's happening.

A simple list view of all emails with performace stats that can then be filtered, is a bare minimum feature and standard across other tools.
