List hygiene
Keeping an email list accurate: fixing mistyped addresses, spotting people who are on it twice, and leaving out addresses that bounce or never engage.

Most hygiene advice is about bounces and inactive subscribers. Duplicates get less attention, though they cost you on two fronts. The same person on two subscribed addresses gets every campaign twice, and if your plan is priced by contacts, they can count twice on your bill.
Keep the decisions in your own hands. MergeGuard for Shopify builds lists that count people, not profiles, and syncs them to Klaviyo only when you choose. Its audiences never unsubscribe or delete anyone. You remove contacts in your email platform. See newsletter cleanup.
