Verizon is testing it’s targeting program, which is opt-in if users want to participate and share their data:
If you’re a customer of Verizon‘s, you’ll want to keep your eyes peeled for an email, text message, or notification mentioning the carrier’s new “Verizon Selects” program. In exchange for sharing your data usage, such as location, web browsing, and mobile app usage data, you’ll get targeted advertisements delivered to you by either email, text messages, or other forms of mobile advertising.
An important point above is that email is mobile advertising. Maybe it’s time for a resurgence in that business.
