Repeat offenders can harm your email marketing efforts in several ways:
Spam Complaints: High spam complaint rates can lead to your emails being blocked by internet service providers (ISPs), reducing your ability to reach legitimate subscribers. Low Engagement: Consistently low engagement from repeat offenders can negatively impact your overall engagement metrics, making it harder to gauge the success of your campaigns. Increased Unsubscribes: Frequent unsubscribing and resubscribing can distort your list growth metrics and waste resources.
