# We've released a feature for getting statistics per aggregation unit

You can now obtain statistics per aggregation unit for multiple push messages and multicast messages. You can assign a unit name before sending messages so that you can see statistics for each unit at a later time.

When is the feature for getting statistics per aggregation unit useful?

When sending a narrowcast or broadcast message to multiple users, you can specify a request ID to get user interaction statistics of that particular message.

User interaction statistics

When sending a message to fewer than 20 users, you can't obtain statistics because users' privacy must be protected. However, with the newly-released Get statistics per aggregation unit feature, even if you send a message to a small number of users, by assigning a unit name before sending the message, you can obtain per-unit statistics on multiple messages.

Aggregating statistics per unit
