What is the purpose of BCC?
BCC, which stands for blind carbon copy, allows you to hide recipients in email messages.
Addresses in the To: field and the CC: (carbon copy) field appear in messages, but users cannot see addresses of anyone you included in the BCC: field..
Can you just BCC an email?
Yes, the various recipient headers are independent of each other. You can BCC a message without any address in the to or CC fields, or you could CC the message without any addresses in the other headers. The only special feature of “To” is that most email clients display it be default in received messages.
What happens if you reply all to a BCC?
Addresses that have been placed in the BCC field are not forwarded. If you have placed a large list of recipients in the To or CC field, all of them will receive the reply. By placing recipients in the BCC field, you can help protect them against receiving unnecessary replies from anyone using the Reply All feature.
What happens if someone replies to a BCC email?
If all your recipients are listed under Bcc:, then none can see or be aware of the others. If any recipient clicks Reply All, the reply will NOT go to anyone they can’t see. Remember they can see any name that’s listed under To: or Cc:, so be careful with mixed addressing.
