Every rule sits in one of three tiers. The tier decides how urgently - and where - you hear about it.
Interrupt (9 rules) - critical. Emails you within minutes and checks very often (every 5-60 minutes). For things that can't wait: security events, accounts going dark, runaway spend, broken tracking.
Operational (8 rules) - day-to-day performance. Appears on your dashboard, checked once a day. No email. CTR collapses, CPA spikes, budget-limited campaigns and the like.
Hygiene (4 rules) - lower-urgency cleanup. Dashboard only, weekly. Negative conflicts, geographic waste, weak assets, PMax placements.
To stop your inbox flooding. If every alert emailed you, you'd quickly start ignoring them - and then miss the one that really mattered. Only the Interrupt tier emails, so an email from Clicc always means "act now". Everything else waits quietly until you're ready to look.
