This idea has been merged into another idea. To comment or vote on this idea, please visit A-I-14637 Integrate Aha! into my daily workflow with an improved Slack integration.
The current slack integration is not meeting our needs. To my knowledge, you can filter the activity stream based upon the person, so only that person's actions are sent to slack.
What at we need is for all email notifications to be routed to slack. This includes notifications about features / ideas etc. that you're watching.
