Description of YouMail Robocall Index

YouMail Robocall Index is the best tool for robocall data and is used by consumers and businesses to block unwanted calls. The YouMail Robocall Index™ estimates monthly robocall volume in the United States. YouMail identifies robocallers by monitoring automated call patterns and behaviors, then verifies that activity against numbers that YouMail customers manually block or report as spam. Total robocall volume is calculated by extrapolating from the millions of YouMail customers to the USA as a whole.
