Are 'Instant In-App' messages affected by global frequency capping settings?

Yes — by default they are. Global frequency capping covers the in-app channel, and instant in-app campaigns are subject to it unless you explicitly opt out.

Global capping applies across channels and sources, including API-based messages, Customer Journey messages, one-time pushes and emails, in-app campaigns, SMS and WhatsApp. Only transactional messages are exempt.

How to control capping for an instant in-app

In the campaign wizard, on the Display settings step, under FREQUENCY CAPPING, choose one of:

• Use Global frequency capping — applies the global in-app channel limit from Settings > Message delivery settings > Frequency capping.
• Send messages without global frequency capping — this campaign ignores the global limit. Use this for critical messages.
• Use custom frequency capping — campaign-specific limits (total impressions, impressions per N days, minimum interval between impressions). Note that the message still counts toward the global in-app counter, so the global limit can still block it.

If a test in-app does not appear

• Check whether the global in-app cap has already been reached for that user, or set the campaign to Send messages without global frequency capping while testing.
• Confirm the trigger event (and any event attribute conditions) is actually being fired.
• Confirm the device matches the campaign audience and the campaign is Active, not Draft or Scheduled.
• Make sure the device has a stable internet connection.
