I only click on like 3-4 personal emails a day, so there's thousands of unread (spam, job, social media account notifications, random stuff i signed up for like website news subscriptions, etc). I have multiple emails for different stuff, but for the most part my personal email inboxes are very unorganized and barely used. My friends/family rarely email me stuff as well. I don't really like checking my personal emails and I think looking at each one is a waste of time when the headline/title is usually enough for me to decide to scroll past or view. If I'm expecting some important mail/email then I'll be a bit more proactive than usual, but I usually don't really care about emails unless it's work related. If my email becomes "full" then I'll just make a new one lol.
