Platform · Ad Audiences
Take your best customers to the ad platforms.
Any Flash segment becomes a Google Customer Match or Meta Custom Audience — a privacy-safe, hashed list you export in one click, consent-filtered before it ever leaves the platform. Retarget lapsed buyers, suppress recent purchasers, or seed a lookalike of your highest-value members.
How it works
Segment → hashed list → ad platform.
Build the segment once
Use the same segments you target for email and loyalty — value tier, lapsed buyers, a lookalike seed. No separate audience tool.
Export a hashed list
One click turns the segment into a file of SHA-256-hashed emails — the exact privacy-safe format Google and Meta ingest. Raw emails never leave Flash.
Upload to the ad platform
Drop the file into Google Customer Match or a Meta Custom Audience to retarget those members — or build a lookalike of your best customers.
Privacy & consent first
Share an audience, not an email list.
Consent-filtered at the source
Members who opted out of marketing or asked not to have their data sold/shared are removed before the file is written — you never ship an opt-out to an ad platform.
Privacy-safe by construction
The file contains only irreversible SHA-256 hashes of normalized emails — the ad platforms match on the hash, so you share an audience without handing over a raw email list.
Your real segments, reused
The same governed segment that drives a campaign drives the ad audience — one definition, consistent everywhere, no CSV hand-rolling.
How it connects
Export a file, or sync straight to your ad account.
The simplest path is the one-click export — a hashed file you upload into Google Customer Match or a Meta Custom Audience. Or connect your Google Ads / Meta account once and push a segment directly, no manual upload. Direct sync uses your own ad account and, for Google, a Customer Match-eligible account; the hashing and consent-filtering are identical either way.
