I want to know when my CEO posts in a public Slack channel. How can I be notified when a specific user posts in any public slack channel I have access to?

Hi Joshua,

Thanks for getting in touch about this. Unfortunately, we don’t have a built-in way for you to handle getting notified when a certain user sends a message.

However, this may be handled if you build a Slack app to monitor the channel and notify you as needed. If you're interested, then you can get started here:

That site will walk you through the various integration points we have available, along with details about the requirements for submitting your app for inclusion in the directory.

I'll also mention this as a feature request to the team and hopefully they'll take this into consideration, but I can't make any guarantees. Thanks for your understanding here.

So Slack doesn't support it, thinking there may be a Slack bot I can create.


Got this answer from Zapier support.

Hi Joshua,

Happy to help! I'd set up a Zap like follows:

  1. Trigger (Slack): New Public Message Posted Anywhere
  2. Filter: Only continue if user_id (or name) is your CEO's.
  3. Action: Whatever you want your action to be.

Bear in mind this requires a multi-step Zap, which is a Premium feature, but it will definitely let you get the results you're after! (In fact, I might steal this workflow for myself...)

Let me know if there's anything I can clarify further for you—super happy to help. :)
