The language of email has its roots in office memorandums

When you select the contacts you are emailing you can place them in one of three fields:

To... Put the email address here if it is for their attention and action

Cc... (Carbon Copy) - Put the email address(es) here if you are sending a copy for their information (and you want everyone to explicitly see this)

Bcc... (Blind Carbon Copy) - Put the email address here if you are sending them a Copy and you do not want the other recipients to see that you sent it to this contact

Here's  a Tip...

If you are sending an email to many people use Bcc... (so you don't give away everyone's email address to everyone else)

Can't see the Bcc field?

Whilst you are composing your email click the Options Tab and then the Bcc button - it looks like this...

So Who can see What?

Here is an example email addressed to nine people:

Ahmed, Barry and Carol can all see that the email was sent to Ahmed, Barry and Carol for their attention/action and they can also see that a copy of the email was sent to Darren, Elaine and Fred for their information

Darren, Elaine and Fred can all see that the email was sent to Ahmed, Barry and Carol for their attention/action and they can also see that a copy of the email was sent to Darren, Elaine and Fred for their information

Gunter, Harriet and Ian can all see that the email was sent to Ahmed, Barry and Carol for their attention/action and they can also see that a copy of the email was sent to Darren, Elaine and Fred for their information

Nobody (including Gunter,Harriet and Ian) can see that the email has been sent to Gunter, Harriet or Ian

What Happens if anyone uses REPLY ALL?

If any of the recipients use the Reply All button it will only send their reply to the people in the To... and Cc... fields (because the Bcc... contacts are hidden)
