The metrics tab shows an overview of your sending history. The metrics will help you monitor your email sending performance and provide a summary of your site’s emails.
The metrics data can be filtered by different date ranges to get specific data.
The sending limit data is unaffected by the metrics filtering. The sending limit is to keep track of how many emails you have sent in your current billing cycle
On the metrics page there is the Sending Limit progress bar to keep track of how many emails have been sent during the current billing cycle. For more information on Sending limits go to Link[Account/Plans/Sending_limit]
