That inbox number is wild-definitely time for some help!
For Apple Mail, you can try built-in Apple Intelligence features (if your Mac or iPhone supports it) to automatically summarize emails and highlight the most urgent ones.
If you want more options, Mailbutler adds a Smart Summarize button right in Apple Mail, and SaneBox offers daily digests to help you spot what matters fast.
To clean up junk and old newsletters, Cleanfox is a one-click tool that unsubscribes and deletes spam, and you can also set Apple Mail to auto-delete junk and trash on a schedule.
If spam is a big problem, SpamSieve is a top-rated Mac app that filters out junk before it even hits your inbox.
With these, you should be able to get that inbox number down (or at least keep it from climbing higher)!
