Effective list hygiene involves several key steps:
Identify Inactive Subscribers: Define what constitutes an inactive subscriber (e.g., no opens or clicks in the last six months) and segment them. Re-engagement Campaigns: Send targeted emails to inactive subscribers to try and re-engage them. Offer incentives or ask for feedback. Remove Invalid Contacts: Use email verification tools to identify and remove invalid or fake email addresses. Unsubscribe Management: Ensure that your unsubscribe process is easy and accessible to avoid spam complaints. Update Preferences: Regularly ask subscribers to update their preferences and interests to keep your list relevant.
