The integration between MoEngage and Slack allows you to receive real-time updates from MoEngage within your Slack channel. You can also import new Slack users into MoEngage and create custom segments for different channels to engage with members separately. Some use cases include sending a Slack message when an event is triggered on MoEngage, creating a new user in MoEngage when a new member joins your Slack workspace, adding a new event in MoEngage when a new mention is sent on a public channel, and adding a user to a cohort in MoEngage when a new reaction is added to a message.
