Definition
List hygiene refers to the ongoing maintenance of email lists to ensure they contain valid, engaged subscribers. Good list hygiene includes removing bounced addresses, unsubscribes, and complainers, sunsetting unengaged recipients, and regularly verifying the list. Clean lists have better deliverability, higher engagement, and lower costs.
