Have you thought about how you safeguard your customer data? What about the marketability of your email list? You should. Data privacy regulations are moving into the United States, with California being the first (but certainly not the last) state to take a strong stance around protecting consumer data. Utilizing opt-in advertising for 100% permissioned leads ensure that you have trackable proof of consent for every email in your database. But you also need to make sure that the database itself is secure and that all data transfers use encrypted methods to protect the data in transit. Opt-in advertising can help maintain data privacy every step of the way.
