Warning: Some people send out their entire client list when they send a bulk email correspondense. This may unscrupulous people to steal your clients etc. The solution is to use the “BCC” feature in your email software. BCC stands for “Blind Carbon Copy”, it is similar to the “To” and “CC” areas but all names in the BCC section will not be visible to anyone receiving the message.
This trick is also usefull when you are sending out an email invitation. Using BCC no one can analyze your guest list to see who you may not have invited (on purpose or by mistake).
