YouMail Launches API to Spur Robocall Blocking Solutions

 Provides Wireless Carriers with Greater Options to Protect Consumers and Businesses

YouMail, a leading provider of intelligent communication services, today announced a new application program interface (API) that enables telecom carriers, private branch exchange (PBX) providers, and third-party developers to programmatically determine whether a given phone number is an undesirable robocaller.

YouMail's new API, available at, provides access to an ever changing and expanding database with data on hundreds of millions of phone numbers. YouMail determines the likelihood that a given number is an unwanted spammer based on data
collected from over 5 billion calls it has processed for users of its intelligent call management services. Among other sources, this includes call patterns, call histories, user data, third-party data, and user feedback.

The new YouMail API addresses a critical and growing consumer problem, as the YouMail Robocall Index revealed that U.S. phones were slammed by a record 2.6 billion robocalls in August alone, up nearly 10% from the previous month. The YouMail for iPhone and
YouMail for Android call management applications already make use of this API to identify callers, and play "out of service" messages to many millions of robocalls each month.

In addition, YouMail's phone number lookup site also uses this API to help consumers determine whether a given number is a spammer. By opening up access to this API to everyone, it is easy for any provider of telephony services, large or small, to determine
whether a caller is likely to be spammer and then take appropriate action, such as identifying the caller as a potential spammer or taking concrete action to block the call.

YouMail released its data API in support of the Federal Communications Commission's newly created Robocall Strike Force, which first met on Aug. 19 in Washington, D.C. The industry-led Robocall Strike Force is made up of telecommunications companies, phone
makers and tech firms that are committed to developing comprehensive solutions for detecting, filtering and preventing unwanted robocalls.

"YouMail's ultimate goal is to help anyone trying to stop robocalls – including carriers, enterprise security companies, and application developers – in order to rapidly protect consumers and businesses from this extremely frustrating problem," said YouMail
CEO Alex Quilici. "There are now multiple ways for carriers to protect consumers from robocalls, whether it's making them aware of apps and solutions like ours, providing integration mechanisms with these apps and solutions that enable them to work better
or be easier for consumers to set up and use, or simply using data like ours to decide which calls to block or identify as potentially problematic."
