কোন ই মেইল CC এর অথ কি ?

When we send an email, we can send it to a person; or mulitple persons. 

CC is the carbon copy of the email which will be sent to other people and everyone will know who are getting the email.

BCC (Black Carbon Copy) is the option to secretly send the copy of an email to other persons. Whoever is in the bcc wont see other bcc email address.
