FAQs

Common questions about our Twitter (X) Audiences integration

Audiences are synced once daily to ensure your targeting remains up-to-date. New profiles that match your segment criteria will be added to your Twitter audience, and profiles that no longer match will be removed.

Only the profile identifiers required for audience matching (such as hashed email addresses) are sent to Twitter. No behavioral event data or purchase history is shared directly.

Yes. Once a segment is synced to Twitter Ads as a custom audience, you can use Twitter's campaign manager to create lookalike audiences based on it for prospecting.

Yes, you'll need an active Twitter Ads account with access to custom audiences. You'll also need to ensure your account meets Twitter's eligibility requirements for audience targeting.

No, it only keeps tailored audiences in sync; campaign creation and budget management still happen in Twitter Ads Manager.
