Only cc people when they must have or should have the information. Routine emails that should not typically include ccs are thank-yous, straightforward yes or no answers (unless everyone must know your answer), brief compliments, and “I don’t know” replies. Also, do not copy people on constructive feedback, denials, or reminders—messages that could embarrass the individual whose name appears on the To line
Use CC when a department, members of a team or a manager need current information about the continual progress of a particular project, event Etc.
When interested parties such as management or team members specifically ask to be kept informed of certain projects or events
CC someone in when you are sending a message to someone else but you’re allowing the people in the CC line to be kept in the loop and you are letting the person you emailed it to; known who else is up to speed
