Where to find it
Open Notifications in the left rail of the Workflow product. The page has two parts: the client's alert channel (pick the client in the client picker first) and your personal Slack settings, which follow you across all clients.
The client's notification channel
When Omega surfaces a new signal for a client, it can post the alert to a Slack channel so the account team sees it without having the app open.
With the client selected, find the Notification channel section.
Enter the Slack Channel ID for the channel where this client's alerts should go.
Leave the field blank to use the org-wide default channel instead — that's the fallback for any client without its own channel.
Check the Posting to line to confirm which channel is currently active.
Send a test before you trust it
Don't wait for a real signal to find out the channel is wrong:
Click Send test message.
Check the Slack channel for the test post.
If it doesn't arrive, the result line under the button tells you what went wrong — most often a mistyped channel ID.
Your personal Slack delivery
The Slack DMs section is about you, not the client:
Turn on Also send my mentions & replies to Slack to get a DM when a teammate mentions you or replies to you in Omega — useful if Slack is where you actually live during the day.
Omega matches your Slack account automatically from your work email. If the match fails (say your Slack email differs), paste your Slack member ID into the override field and save.
Click Send me a test DM to confirm delivery. The result line explains any failure — for example, if the toggle above is off, or no Slack account matched your email.
Tip: Set the notification channel as part of client onboarding, right after metrics and coverage. The usual pattern is the client's internal team channel — alerts reach the people who'd act on them, without waiting for someone to check the board.
Note: In-app signals are unaffected by any of this — everything still appears in Omega regardless of Slack settings. Also, demo clients never post to Slack by design, so don't be alarmed when a test for one stays in-app only.
