How to filter out users with mobile phone numbers who have opened a US securities account and WhatsApp at the same time
If you want to promote financial services, especially to American users with investment behavior, no matter how much data you have, it is not as practical as a group of precise users who can communicate, convert, and close transactions. Many companies hold the registration data of U.S. securities accounts and can even obtain mobile phone numbers. However, once messages are sent, they are not read or replied to, and all numbers are empty or blocked. At this time, you should use a method that can truly screen out "alive users" - WhatsApp mobile phone number detection. And not only can it screen, the Digital Planet platform can also directly help you handle the entire process.
