Why is it a good idea to clean out your email list every few months?

Regularly cleaning your email list removes inactive subscribers, which improves your sender reputation. Internet Service Providers (ISPs) monitor engagement rates; sending emails to a large number of unengaged recipients signals low-quality content, increasing the likelihood of your emails being flagged as spam for all recipients, including active ones. Maintaining a clean list ensures higher deliverability and better open rates. An email list size of 5,000 is an arbitrary number and not the primary reason for cleaning. Email marketing tools do not automatically clean lists without user instruction. You should not remove customers based on personal preference but rather on their engagement with your emails.
