YouMail maintains the industry's foremost collection of phone numbers and it's free for anyone to search. Our patented technology allows us to track behavior patterns, find people that abuse the Telephone Network, and prevent those calls from reaching our users.
To answer the question, yes, the Public Directory is safe for personal contacts but just know that anyone can access the YouMail Directory. Please know that syncing your contacts to YouMail will show the name saved in the phone, once they leave a message, it will display what is saved in the YouMail contacts
Although all synced contacts get listed in the directory, the public Directory itself is meant to look up and report nuisance phone numbers. No one will have access to your contacts unless they look up the phone number directly. YouMail cares about our user community so we stay on top of the most frequent robocall scams.
