The opt-out page builds its whole framing around residents of twenty states with privacy statutes. California, Colorado, Connecticut, Delaware, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah and Virginia.
Be clear about what that is and isn't. It's a statement of where Carney Direct believes its legal obligations bite. It's not a statement that it will refuse anyone else, and nothing on the page says it will. But it's also not an offer to anyone else, and the form gives you no way to say where you live. The only region field on it is hidden, and it's fixed to us for everybody.
If you're in one of the twenty, submit the form and name your state and its statute in your email as well. You have a specific law behind you and it's worth saying so.
If you're not, the form still submits, but the email route is the better use of your time, because an email has room for you to make the request in your own words rather than as a checkbox on a page written for somebody else.
