GERTES® is a brand new way for you to find out how well people and organizations respond to email. The left-side "Response" panel of the GERTES performance badge (shown below) shows the most common expected email response-time for an individual, organization or organizational group.
The right-side "Grade" panel shows how well the expected response-times were met (A+ being 95%-100% and F being less than 50% of the time— see the Grade Key below for more grades).
