Here are several steps to ensure effective email list hygiene:
Validate Email Addresses: Use email verification tools to validate new and existing addresses. Remove Hard Bounces: Immediately remove email addresses that result in hard bounces. Segment Inactive Subscribers: Identify and segment subscribers who haven't engaged with your emails in a specified period. Re-Engagement Campaigns: Send targeted emails to inactive subscribers to win them back. If they remain unresponsive, consider removing them. Monitor Engagement Metrics: Regularly track open rates, click-through rates, and other engagement metrics to identify trends and take action.
