I am currently utilizing the Kakao Moment Friend Group Management API and would like to confirm the capabilities regarding user subscription verification. Based on the documentation and our testing, we understand that after uploading a friend group (via phone numbers or service user IDs), the API response returns only the total number of successfully matched users (successCount), but does not provide individual-level subscription status.

This limitation has presented some challenges when integrating Kakao Moment with external marketing platforms. Specifically, when preparing to send messages, our clients often wish to set a maximum delivery cap (e.g., send to only the first 10,000 matched users). However, since the estimated number of Kakao Talk subscribers in a group can exceed the client’s desired send volume, we are unable to manage this cap proactively.
As a result, the actual list of users who receive the message can only be confirmed after the message is sent and the delivery status is returned, making it difficult to pre-control cost or exposure volume as expected.
Could you please advise:
- Is there any existing or upcoming method (API or otherwise) that allows us to verify the subscription status of individual users before launching the campaign?
- Are there any recommended workarounds or best practices to handle audience size control more precisely when using Kakao Moment via external systems?
