How large can an audience be?
Platform limits are generous, typically in the millions of members, and Datahash chunks uploads to stay within each platform's API constraints. Minimum sizes matter more in practice; we flag segments too small to serve reliably, since a platform may suppress a custom audience entirely rather than run a campaign against too few matched users.
How often do audiences refresh?
On the cadence you choose, from event-driven near real time to daily or weekly batches, set per audience rather than fixed platform-wide. Refreshes send incremental adds and removes, so audiences track your source of truth without full re-uploads, and a customer who churns or opts out drops from the audience on the next cycle.
Do you support Segments?
Yes. Segments built in Datahash, including predictive and rule-based cohorts, are first-class audience sources and sync to every connected destination the same way a CRM list or warehouse export does. A propensity-to-churn segment or a high-LTV cohort updates on its normal refresh schedule and reaches Meta, Google, Snap, TikTok, LinkedIn, and X together.
