Keeping a Clean Subscribers List: Handling Bounces

Learn why keeping your email list clean improves deliverability and ensures your messages reach the right audience.

🛠️ Best Practice: Keep Your List Clean

Keeping your subscriber list healthy is essential for strong deliverability and engagement. Over time, inboxes go inactive, people change jobs, or emails are mistyped — leading to bounces and low performance if left unchecked.

Tips to maintain list health:

  • Clean regularly: Review your list every 3–6 months to remove or suppress invalid addresses.

  • Rely on suppression: Most ESPs automatically suppress hard bounces, protecting deliverability while keeping your records intact.

  • Segment by engagement: Separate active vs. inactive subscribers and consider re-engagement campaigns before removing inactive contacts.
