After clicking with the mouse, new mail this box will appear which has the purpose of understanding who you are going to send an email to. In the box where it has FRANKIE OWEN that is who is going to be sending the message to whoever that person wanted to send a message to. The box which has “subject” in front of it simply means for example if you were going to send a message to someone about flowers you may put “flowers” daises” poppies” etc. CC means copying it twice so if you wanted to send this certain message to Gary and Mary then you would press CC but if you wanted to have a BC which means blind copy would mean you would send a message to Gary but Mary wouldn’t know you had sent that message to him.
