Maintaining good email list hygiene is crucial for several reasons:
Deliverability: A clean list ensures that your emails are more likely to reach the inbox rather than being marked as spam. Engagement: Sending emails to active subscribers increases engagement rates like open and click-through rates. Reputation: A high-quality list helps maintain a good sender reputation with ISPs (Internet Service Providers). Cost-Effectiveness: Many email marketing platforms charge based on the number of subscribers. Removing inactive addresses can save costs.
