What you should I never include in a CEO email signature​?
Avoid too many links – too many links can make your signature look over-crowded, noisy and unprofessional.
Refrain from adding quotes – Your clients, prospects and colleagues may have very different ideas on whether the quote you use hits the mark or sounds lame.
Don’t upload an inappropriate photo – Make sure any photo you include lives up to your professional reputation. Keep it high quality and conservative with regards to your clothes and facial expression.
