When you send an email message, you don't always have to send it to just one person. There are a number of ways to send the same message to a number of different people.
Multiple To recipients inline
If you want to send the same message to a number of different people, just separate their email addresses by a comma.
Example:
support@jomail.net, info@jomail.net, whoever@jomail.net, elder@bizland.com
Cc
You can send the message to other
people by putting their email address in the Cc line. Cc
stands for Carbon Copy. This line is designed to send someone an
email without actually sending it directly to them. They will get the message
just like all the other people, however in the message header, their address
will be in the Cc line rather than the To line.
Bcc
Using Bcc, which stands for Blind Carbon Copy, you can send an email to someone without all the other recipient knowing that the Bcc recipient got the email. This can be used in any number of ways.
