This dashboard shows you a list of the contacts that you have sent to the most. It is a useful way to identify contacts across your entire list who are receiving a lot of emails. We recommend that you investigate these contacts a little further to see whether they are engaging with your emails. If they are not, it's definitely worth reducing the frequency with which you email them.

You can send this dashboard to yourself or your colleagues either once or on a recurring basis. Find out how to do this

You can filter this report by date range and also exclude any specific email addresses.
