[SalesForce] way to track email client within Marketing Cloud

I want to find out if it's worth my time to design our emails to work in Outlook YYYY but I don't know how many users are using various email clients. Is there a way to find this out in Marketing Cloud?

There is an 'Email Performance by Device' report available, but you will need to have Discover enabled on your account (which is included in corporate and enterprise editions). However, this provides limited analytics and you can only filter by date (not send).

The best method would be to add Litmus tracking code to your emails, which enables you to see a breakdown by client, and also how much time they spent reading your emails. Refer to screenshot below. You can sign up for a free trial at litmus.com.
