When sending email to multiple recipients (some of whom are unknown to each other), it’s recommended not to display everyone’s email address. Some people might get quite upset with you for advertising their email address to people they don’t know.
Generally, when you send email to multiple recipients, you enter their email addresses in the Cc (Carbon Copy) field, where their addresses are visible to everyone receiving the email. This is acceptable if all the people already know each other and may even have the email addresses. However, if some of the people you’re including in the Cc field do not know each other, it’s not a good idea to use the Cc field and advertise everyone’s email address to everyone else.
This is where the Bcc (Blind Carbon Copy) field comes in. Putting an email address in the Bcc field basically instructs the mail server to take off the address label before delivering the message so anyone receiving the email message cannot see who else received it. So, you can put all the email addresses of the recipients in the Bcc field. However, only putting email addresses in the Bcc field, with no address (or your own address) in the To field, may cause the message to be flagged as Spam by some junk email filters.
There is a way around this. We will show you how to use your own email address as “Undisclosed recipients” for the To field and add the other email addresses to the Bcc field so you can safely send your message.
Open Outlook and click the People link on the Navigation Bar.
In the Full Name edit box, enter a name for this contact that will display in the To field. You can call it “Undisclosed recipients” or any other name you want. Enter your own email address in the E-mail field and click Save & Close.
The Bcc field is added to the Message window. Add the email addresses for all the people you want to receive this email either by clicking the Bcc button and selecting them, or by entering them manually in the Bcc field. As you start typing an address in the Bcc field, a matching address from your address book is suggested.
NOTE: You can also create a distribution list containing all the email addresses you to which you often send emails as a group. See our article about creating distributions lists in Outlook 2013 to find out how.
