As an expert SEO copywriter, I can tell you that buying email lists can be a risky and costly endeavor. The cost of purchasing an email list can vary depending on the size and quality of the list. However, the true cost of buying email lists goes beyond the initial purchase price. Buying email lists can damage your reputation and credibility as a business, as many of the contacts on the list may not have given permission for their information to be shared. This can lead to high rates of unsubscribes, spam complaints, and even legal consequences. Instead of buying email lists, it's better to focus on building your own list through opt-ins and targeted marketing strategies. This way, you can ensure that your email communications are reaching people who are interested in hearing from you and are more likely to engage with your content.
