Privy ‑ Email, SMS & Pop Ups

I have 1,000 people who signed up for email. Only 300 are mailable and 220 can be texted. It is very frustrating that I can have an offer pop up in exchange for email and text, customers sign up, but since they didn't click the stupid check box (that isn't required by the customer), I can't contact them?! WHAT A WASTE.
