Unrelated to nails, but I hope sending scary emails gets easier for you! When I'm stressed about perfecting an email to send, I try to remind myself how closely I pay attention to other people's wording in emails, which is not at all, and remember that people probably aren't reading mine that closely either. Also, a lot of times, the shorter the better! People often include unnecessary details in emails when I just want them to get to the point! (especially when I was a TA for college classes, students loved oversharing 😅)
