Mail Gmail What to Know Click Show Cc & Bcc (above the To line). Type recipient's email address in the Bcc field or select Bcc to choose from Contacts.For more than one recipient, separate email addresses with semicolons. The BCC function lets you send a message to recipients without them knowing who else received it. Here's how to use it in Hotmail. When to Use BCC The To: field, of course, is all you need to address a message in Windows Live Hotmail. What if you want to avoid a long list of email address in that field, or need to copy somebody without their address visible to other recipients? For these needs, you get Bcc: — blind carbon copy. Recipients in this field will get a copy alright, but their addresses are deleted before the message is delivered (to all recipients). Windows Live Hotmail does not expose the Bcc: field right away, but adding recipients to it is still easy. Add a Bcc: Recipient to a Message in Windows Live Hotmail To add recipients to the Bcc: field when composing a message in Windows Live Hotmail: Click Show Cc & Bcc (right above the To: line and to the right).Type the desired recipient's email address in the Bcc: field or use the Bcc: button to select people from your contacts.If you add more than one recipient, separate them with semicolons (like: "tina@example.com; tim@example.com"). Using Bcc: you can also send an email to "undisclosed recipients" from Windows Live Hotmail. Was this page helpful? Thanks for letting us know!
