If you get a task or notification from the system. you can be notified in slack.
Your email inbox will keep light and tidy, while you'll still be up to date with what you have to do.
If you organize workflows across departments, give one slack channel for each department.
This way all the members of the department group can see new group tasks, or pick and delegate directly from Slack.
Why even bother to enter devolute.cloud dashboard just to start a workflow?
If you or your slack admin integrates Dashboard with Slack, you can start the workflows you have access to from anywhere.
