Slack Metric
Collaboration
Notification Engagement Rate = Notifications Acted On / Total Notifications × 100
Notification Engagement Rate measures the proportion of Slack notifications that result in user action - opening the app, reading a message, or responding. It reveals whether notifications are driving productive engagement or being ignored due to overload.

How to calculate notification engagement rate
Why notification engagement rate matters for Slack users
Notification overload is a leading cause of Slack fatigue. When users receive hundreds of notifications daily, they learn to ignore them - which means critical messages get lost alongside routine noise.
For Slack administrators, engagement rate by notification type reveals which notifications add value and which contribute to fatigue. This data informs workspace-wide notification policies and helps users configure their personal settings for better signal-to-noise.

Alert Fatigue Score
CollaborationMetric Definition
Alert Fatigue Score quantifies the degree to which automated alerts in Slack overwhelm recipients, measured through alert volume, acknowledgement rate, and the ratio of actionable to informational alerts. High fatigue scores indicate that noise is drowning out genuine signals.
User Activity Score
CollaborationMetric Definition
User Activity Score is a composite metric that blends multiple engagement signals - messages sent, reactions given, threads participated in, files shared, and app interactions - into a single score per user. It provides a balanced view of Slack engagement that goes beyond raw message count.
Emoji Reaction Rate
CollaborationMetric Definition
Emoji Reaction Rate = Messages with Reactions / Total Messages × 100
Emoji Reaction Rate measures the proportion of messages that receive at least one emoji reaction within a given period. Reactions serve as lightweight acknowledgements in Slack - a way to confirm a message was read, signal agreement, or express sentiment without generating a full reply.
Message Response Time
CollaborationMetric Definition
Message Response Time = First Reply Timestamp − Original Message Timestamp
Message Response Time measures the elapsed time from when a message is posted in a Slack channel to when it receives its first reply, either as a thread response or an in-channel follow-up. It reflects the responsiveness of communication within the organisation.
