You can edit Slack and email notifications within Notification tab in Settings. Set up a Slack connection, by clicking on the Add to Slack button. From there, you’ll be prompted to authorize the connection and select which Slack channel you’d like to receive updates.

You can also choose what metrics go into daily and weekly email reports:

You can also choose to receive reports for all individuals or to only receive notifications for the team or cohort you’re responsible for.

To set up a new alert, click 'Add Subscription.' From there, you can decide which teams you'd like to receive e-mail and Slack alerts for.

Note that you can add as many customized subscriptions as you'd like.
