The pattern that defines who not to contact, based on conversion state, opt-out, fatigue, recent contact, or campaign-specific exclusions. Distinct from positive targeting because the failure mode is invisible: suppression failures show up as customer complaints, not as data quality issues. Foundational to recipes like post-conversion suppression, re-engagement gating, and consent-aware activation.
The capability a stack needs to run this pattern, and the vendors that provide it, on Martech Stack Builder.
Activate the target account list with one identity resolution and one exclusion list across paid display, paid social, direct mail, and BDR outreach, so the same account stops getting contradictory treatment
Stop bidding against yourself for the same person across Meta, Google, TikTok, and the rest, by maintaining a single live audience exclusion the platforms read
Push first-party signals (predicted value, churn flag, recent conversion) to ad platforms as bid modifiers so the platforms stop paying premium for impressions that will not convert
Stop sending the same offer through email, push, and SMS in the same hour, so the customer experiences one message about one thing rather than three timed competitions for their attention
Push the segments you own to the ad platforms, as seeds and as targeting, instead of renting the platforms' own decaying interest signals
Cap contact at the person, not per channel, so the customer stops getting hit five times a day by systems that do not talk to each other
Keep customers in legal hold, dispute, or vulnerability status out of every marketing channel, with the audit trail a regulator will ask for
Push one unified do-not-target list to every paid platform, so spend stops chasing existing customers, recent buyers, and known unfits
Stop showing ads to people who already bought
Cross-platform suppression with consent propagation
Carry the deletion request from the source system to every downstream destination holding the customer's data, including active campaigns, queued sends, and cleanroom audiences
