Questions your team will ask.
What identifiers does Snap match on?
Hashed email, phone, and mobile advertising IDs. Datahash hashes everything before upload and picks the strongest key set your source data supports, whether that source is your CRM, a warehouse table, or SingleView. Segment rules and hashing run in the same step, so the identifiers Snap receives are never exposed as raw customer data at any point in the sync.
How often do audiences refresh?
On the schedule you choose, from hourly to weekly. Refreshes send incremental adds and removes, so segments track your source of truth without full re-uploads. This keeps suppression lists and lookalike seeds current as customers convert or churn, without the manual list exports teams used to push to Snap Ads Manager by hand.
Can the same segment feed Snap and other platforms?
Yes. A segment defined once in Datahash can sync to Snap, Meta, Google, and TikTok simultaneously, each with its own hashed key handling suited to that platform's audience API. You maintain one segment definition and one refresh schedule instead of separate exports per channel, and updates to the underlying source data propagate to every connected platform on the next sync.
