Revisiting and scrubbing your subscriber list every few months can help improve email performance.

True. Regularly reviewing and cleaning your subscriber list is crucial for maintaining email performance. Removing inactive subscribers, bounced email addresses, and those who have unsubscribed improves deliverability rates by reducing the likelihood of being flagged as spam. It also ensures your engagement metrics (open rates, click-through rates) are more accurate, as they reflect the activity of genuinely interested recipients. This practice optimizes your email marketing budget by focusing efforts on an engaged audience and helps maintain a positive sender reputation with Internet Service Providers (ISPs).
