Set up filters and rules

We receive 800 messages a day into sales@company.com. Create filters that tag new leads with label Lead, move internal notices to Internal, archive newsletters, and star messages from vip@big-client.com. Apply filters only to messages sent to sales@company.com, ensure filters run before forwarding rules, and test by forwarding three sample messages from newlead@prospect.com, newsletter@partner.com, and alice@company.com.

Before I publish these filters for sales@company.com, make approval easy for the revenue ops lead: surface the rule that assigns Lead label, show which keywords and domains it matches, highlight any rules that could mislabel a partner newsletter as a lead, and list a one-paragraph rollback instruction if a rule misfires.

I just added filters to tag and archive messages but a client complaint says their email landed in Archive. The people involved are me, the account owner Maria, and the client contact Justin; I can't see which rule matched Justin's message. What's the most likely cause and the immediate steps to find and fix the offending filter without disrupting other rules?

Every quarter we add more filters to handle new campaigns and people complain that real leads get archived. Where are we losing control—rule naming, lack of testing, or too many ad-hoc filters—and which single habit change will reduce misclassification most effectively? Give the daily or weekly action to enforce it.
