People only respond well to emails they asked for. Why would anybody ever give permission for their personal data to be sold repeatedly for a couple of dollars? Neither you nor anyone else likes to receive unsolicited emails. These subscribers may have opted in for real estate offers, but now they’re receiving your offer for a totally different service! Even if you’ve taken the time to create a well-targeted list, it doesn’t change a thing if the recipients didn’t opt in. Please keep in mind how you feel when you receive unsolicited emails. Think about it. Would a legitimate company really sell a list of high-quality customers that took years to accumulate – and risk losing ALL those customers after the first unsolicited campaign?
