How do you send GitLab MR notifications to Slack without spam?
HotBot sends a daily digest of your GitLab merge requests to Slack instead of blasting every event as a separate message. WIP MRs, drafts, and bot activity get filtered. Your team sees what actually needs attention.

GitLab Slack app vs webhooks vs a digest tool
GitLab for Slack app (the native integration) posts a message for every subscribed event: pushes, pipelines, comments, issues. On a busy project that means dozens of Slack messages a day, most of which nobody reads. The legacy Slack Notifications integration (webhooks-based, deprecated by GitLab) behaves the same way with more manual setup.
Raw incoming webhooks give you full control at the cost of building it yourself: you wire pipeline or push events to a Slack webhook and own the filtering, formatting, and noise reduction from then on.
A digest tool like HotBot takes a third position: one filtered daily message per channel with CI results, review status, and escalation for stale merge requests. WIP, drafts, and bot MRs are filtered out before anything is posted.
Rule of thumb: under a handful of merge requests a day, the native app is fine. If you need pipeline-specific routing, build webhooks. If your channel is busy enough that people mute it, a digest is the fix.
How do you reduce GitLab notification noise in Slack?
Three levers, in order of effort: subscribe to fewer events in the GitLab for Slack app, route different event types to different channels, or collapse everything into a single daily digest so nothing fires in real time except what you escalate.
HotBot does the third: it filters WIP, drafts, and bot activity, then posts one digest with CI results and review status. Stale merge requests escalate on a schedule you set.
