Send email to undisclosed receipients

It's easy. In Window Mail, we uses Bcc: recipients and cleverly puts as the main recipient to send her emails to "undisclosed recipients" — a bumpy title for sure, but it works well.

Create an Address Book Entry for "Undisclosed recipients"

First, we'll create a convenient address book entry that makes sending emails to undisclosed recipients a lot easier:

Windows Mail:

Select Tools | Windows Contacts... from the menu in Windows Mail.
Click New Contact.
Type "Undisclosed" in the First: field.
Type "recipients" under Last:.
Enter your email address under E-mail:.
Click OK.
Outlook Express:

Select Tools | Address Book... from the menu.
Click the New button in the toolbar and select New Contact....
Type "Undisclosed" in the First: field.
Type "recipients" under Last:.
Type your email address under E-Mail Addresses:.
Click Add.
Now click OK.
Send an Email to Undisclosed Recipients in Windows Mail or Outlook Express

To compose and deliver an email message to a group of undisclosed recipients in Windows Mail or Outlook Express:

›› Step by Step Screenshot Walkthrough (Outlook Express)
Start with a new message.
Click on the To: button with the address book icon.
Highlight your "Undisclosed recipients" entry.
Click To: ->.
Highlight all other desired recipients.
Click Bcc: ->.
Click OK.
Now you can add any additional recipients in the Bcc: field.
Make sure you separate recipients by semicolons.
If you do not see the Bcc: field, select View | All Headers from the menu.
Compose and eventually send your message.
