Email opt-in laws
We have sent out an email to a purchased list that included the following question: “Would you like to continue to receive emails from our company?” They can then choose yes or no. If they clicked no, I ran a triggered campaign to change them to unsubscribed so we don't risk emailing them again. Keep in mind that these are not customers of ours, just potential prospects. My question is, If they don’t click on yes or no, are we allowed to send another email to them? Or can we only send to those who actually clicked yes? If you happen to have a document/link that explains these legal issues, that would be great.
