The Cost of Email List Attrition

Businesses typically lose 30 to 50% of their email list each year, which can significantly impact growth, especially for those investing in paid ads to build that list. This attrition is caused by reasons such as job changes, users abandoning old email addresses, and declining engagement. As email lists diminish, the effectiveness of advertising spend also decreases, leading to wasted resources. Understanding these dynamics is crucial for marketers, as it highlights the importance of engaging subscribers from the outset to enhance retention efforts.
