Buying email lists for affiliate marketing can lead to serious problems. In most countries, especially in places like the US, UK, and Europe, sending emails to people without their permission is against the law. Laws like GDPR and CAN-SPAM require that people agree to receive marketing emails. If you buy a list, you don’t know how the emails were collected, and that can put you at risk of legal issues or getting reported for spam. Also, email platforms don’t allow sending to purchased lists. They can suspend or block your account if they find out. Even if you somehow get away with it, most people on those lists don’t know you, and they won’t trust your links. This makes it harder to get clicks or sales. It's better to build your own list. That way, people are more likely to open your emails and take action. Has anyone looked into this from another angle?
