Improving list quality involves several strategies:
1. Regular Cleaning: Periodically remove inactive subscribers, bounced emails, and addresses with typos. 2. Double Opt-In: Use a double opt-in process to ensure that subscribers genuinely want to receive your emails. 3. Segmentation: Divide your list into smaller, targeted groups based on demographics, behavior, or preferences. 4. Re-Engagement Campaigns: Send targeted emails to inactive subscribers to try to re-engage them. 5. Quality Content: Ensure your emails provide valuable, relevant, and engaging content.
