What is one reason to avoid sending marketing emails to purchased lists?

Sending marketing emails to purchased lists can harm your sender reputation due to several factors associated with email deliverability and recipient engagement. When you send emails to individuals who have not opted in to receive communications from your brand, this increases the likelihood of your emails being marked as spam. High spam complaint rates can lead email service providers to classify your emails as unwanted, decreasing the chances of your future emails reaching the inboxes of genuine subscribers.

Additionally, poor engagement metrics such as low open and click-through rates can signal to email providers that your content is not relevant to recipients, further damaging your reputation. Over time, a tarnished sender reputation can lead to increased difficulties in delivering emails, including being blacklisted, which can have long-term negative effects on your email marketing efforts.

In contrast, options suggesting benefits like immediate sales or high open rates fail to account for the sustainability and long-term impact of maintaining a reputable sender status within email marketing practices.
