COMMON SOURCES Unwanted email often comes from newsletters, marketing lists, old subscriptions, automated notifications, and spam campaigns. WHAT TO DO Unsubscribe from legitimate newsletters you no longer need. Mark obvious spam as junk. Create rules for low-value automated messages only if you still need to keep them. BE CAREFUL Do not click unsubscribe links in suspicious messages. That can confirm your address is active. For suspicious email, report or mark as spam instead. PREVENTION Avoid posting your email publicly and be careful when signing up for forms, downloads, and contests. MAINTENANCE Review inbox rules and subscriptions periodically so noise does not slowly rebuild.
