The onboarder for lookalike and suppression audiences

Reach likely buyers. Stop paying for the wrong ones.

ArcMirror onboards your own customer list into your ad accounts as two audiences: a super-targeted lookalike of your best customers, the easiest wins, and a suppression set that removes the people who sit in the right demographic but are unlikely to ever buy.

Why ArcMirror

Two audiences that move the whole media plan.

A super target of your easiest wins

ArcMirror ranks your customers by recency, spend and frequency and hands the platform your best customers as the lookalike seed. The result is a tight audience of people who look like the ones who already buy the most, not a broad segment that merely resembles them.

Clean up your broad buys

Broad buys reach the right demographic and the wrong people at the same time. ArcMirror's suppression set removes both kinds of waste: everyone you already have, and everyone who looks like your worst customers, the people who fit the profile but were never going to be interested.

One onboarder, starting with Meta

ArcMirror does the onboarding itself. It hashes your list, delivers both audiences into the ad account you connect under your own name, keeps them current when your list changes, and shows how many people the platform matched. Meta is live today. Google Ads, DV360, TikTok, LinkedIn, Pinterest, Snapchat, Reddit, X and StackAdapt are built and switch on as each platform approves ArcMirror.

How it works

From customer list to live audiences in your ad account.

1
Upload your customers

A CSV with an email column, plus a purchase date, order value or order count so ArcMirror can rank. Delivering the list as-is? Emails alone will do. Every address is hashed the moment it lands.

2
Rank by value, or skip it

ArcMirror scores your customers on recency, spend and frequency. Only need to clean up broad buys? Deliver just the suppression audiences. Prefer the list exactly as uploaded? Choose that instead.

3
Build the two audiences

A super-targeted seed from your best customers, and a suppression set: everyone you already have, plus a do-not-target seed from your lowest tier. Where the platform offers lookalikes, ArcMirror also builds one to target and one to exclude.

4
Deliver to your ad account

ArcMirror pushes the audiences into the ad account you connected and keeps them current. Or download the hashed lists and go.

“Most media budgets pay twice: once to find the right people, and again to chase the wrong ones. ArcMirror fixes the second half.”
