-Usage of this event is discouraged for several reasons:
--   The number of feedback events will grow very quickly with the number
-    of users in the room. This event provides no way to "batch"
-    feedback, unlike the [receipts module](#receipts).
--   Pairing feedback to messages gets complicated when paginating as
-    feedback arrives before the message it is acknowledging.
--   There are no guarantees that the client has seen the event ID being
-    acknowledged.

-description: '**NB: Usage of this event is discouraged in favour of the** [receipts module](/client-server-api/#receipts). **Most clients will not recognise this event.** Feedback events are events sent to acknowledge a message in some way. There are two supported acknowledgements: `delivered` (sent when the event has been received) and `read` (sent when the event has been observed by the end-user). The `target_event_id` should reference the `m.room.message` event being acknowledged.'
