I definitely pause before sending emails (and even making posts). I tend to read, proofread, re-read and then send. I proof my emails because I don't always know who's on the other side and if they are as picky as me. I tend to get cranky when I know the person on the other side is someone who writes for the public (like a PR person or marketing person) and who has horrible typos and grammar. Seeing emails like that makes me lose faith in the school systems here 🙁
