This metric measures the total number of emails which were sent from this inbox in the time period covered by the report.
You may see a percentage which reflects the change in this number from the previous time period - this can either be green if more emails have been sent, or red if less have been sent.
There will also be a highlight of one of your metrics which has shown an improvement, and this can be the Sent metric.
Advanced Filters can affect this number, for example if you choose to exclude a certain domain or address from your report.
Great for quickly seeing the volume of emails you have sent for the time-period you are analysing.
