Enable desktop notifications

I need to be alerted immediately for high-priority emails on my desktop. Turn on desktop notifications for new important mail only, not for every message. Use the account’s current importance markers so only messages marked Important trigger a desktop pop-up. Confirm that the setting is enabled and show an example notification within the next incoming important message.

Before enabling desktop notifications, make them useful instead of noisy. Show which senders and filters currently mark messages Important, estimate how many desktop pop-ups per hour that will create during business hours, and recommend a rule to suppress notifications from distribution lists or low-priority automated systems. Flag any sender that will generate notifications and should be excluded to avoid alert fatigue.

I just enabled desktop notifications for important mail and my screen started filling with alerts from release CI bots and marketing digests. I don’t know which filters treat those as Important. I’m worried I’ll miss the real exec-level alerts under the noise. What’s the likely cause, and what immediate steps remove the noisy sources from desktop alerts without cutting off any human-sent high-priority messages?

I keep turning desktop notifications on when I’m worried about response time and off when they become noisy. That oscillation costs me attention and makes me miss decisions. Where does this pattern waste the most time, and what one change to notification rules or sender lists will give reliable, low-noise desktop alerts that I can keep on permanently?
