The most common sentence we hear from people leaving ClickUp is not "it can't do X." It is "I've muted it. Everyone has muted it." A notification for every field change on every task in every project you were ever added to is not a feature. It is how a team trains itself to ignore the tracker.
The firehose is a design choice
Default-on, everything-fires notifications feel thorough in a product demo. In week three they mean the mention that actually needs you is sitting under forty "someone changed a due date" emails. Muting the channel is the rational move. Once the channel is muted, the tracker stops being the place status lives, and Slack becomes the tracker again.
Per-channel modes, then per-activity switches
IterDone's notification settings start with a mode per channel (Inbox and Email): everything, focused, mentions only, custom, or off. Focused is the default most people want. Custom is for the person who wants mentions and assignments but not "someone moved a due date." Inside custom, each activity is its own switch. Tune it once.
What "I've muted it" is actually saying
It is not a complaint about volume as such. It is a complaint that the tool cannot tell an @mention from a field twitch, so the only lever left is off. A mode named "mentions only" is a small thing to ship and a large thing to get back: the inbox becomes a list of things that need a person, not a changelog.
