Someone buys in-store on Saturday, then sees your new-customer ad on Instagram on Monday. The ad platform has no idea they’re the same person. Neither do you, because that customer checked out as a guest, used a different email, and left no obvious trail to connect. This is the suppression problem at its most expensive: prospecting budgets quietly funding redundant impressions, inflating conversion metrics, and frustrating the loyal customers you already worked hard to win. Without person-level identity that spans every channel, you can’t suppress who you can’t recognize.
The Amperity Approach
Amperity builds a suppression engine that works at the person level, not the email level, so every dollar in your prospecting budget is pointed at genuinely new acquisition opportunities.
Suppress the person, not just the email. Amperity’s multi-patented identity resolution links email hashes, phone numbers, and device IDs into a single trusted profile. When that profile converts, suppression applies everywhere, not just to the identifier the ad platform happens to know.
Lists that update as fast as your customers act. Customer profiles update dynamically as new transactions and events come in, so suppression audiences reflect current reality rather than last week’s export.
Complex suppression logic, no engineering ticket required. Amperity’s Customer Data Agent lets marketers build suppression lists based on predicted CLV, loyalty status, or offline transaction history without waiting on IT or data engineering to pull the data.
How to Get Started
Segment: Build suppression segments based on recent transactions, customer lifetime value, loyalty status, and brand relationship (including employees). Include all relevant ad platform identifiers such as email hash, mobile ID, cookie ID, and UID 2.0.
Onboard: Sync audiences in real time to Google, Meta, The Trade Desk, TikTok, and other paid platforms.
Suppress: Activate suppression lists across every paid channel to remove existing customers, recent purchasers, and employees from prospecting campaigns.
Measure: Track incremental ROAS, CPA improvement, and overall campaign performance. Prove the ROI. Repeat what works.
Every dollar spent reaching someone you already converted is a dollar not spent finding someone new.
See how Amperity helps brands build suppression audiences that actually work, so prospecting budgets go further and loyal customers stop seeing ads for products they just bought.
