Wjhen you block callers, WhoAreYou sends them to your voicemail. And when that voicemail is YouMail:
* Blocked callers automatically hear an official “This number is out of service” before it hangs up on them.
* Blocked callers think your number really is out of service! They won’t want to call you again!
* Telemarketers will take you off their call lists, and they won’t call again - from any of their outbound numbers.

One simple call block with WhoAreYou may stop 100s of calls from ever being made to your phone! Plus, YouMail’s Smart Blocking ensures that many numbers will be automatically blocked without you doing a thing.
WhoAreYou will sync with a new free YouMail account (if you don’t already have one). This allows you to automatically backup your blocked callers list (Blacklist), easily add/edit any uploaded contacts online at youmail.com, take advantage of YouMail’s existing database of trove of Caller ID information.
