I totally get where you're coming from because I dealt with the exact same nightmare last year. The email back-and-forth was killing my productivity and making me look unprofessional. What really helped me was switching to an actual booking system instead of trying to manage everything manually. The key thing is finding something that syncs with your existing calendar so you don't have to maintain two separate schedules. Look for solutions that let you set your available hours, block off time you need for other work, and then generate a link you can share with clients. They pick a time that works for them from what you've made available, and boom, it's done. No more endless email chains asking 'does Tuesday at 3pm work? How about Wednesday at 2pm?' It's been a game changer for me.
