How to Use To, Cc, and Bcc With the Thunderbird Email App

Thunderbird's Cc, Bcc, and to fields are how you send email messages

What To Know

  • Use the Cc and Bcc fields in the compose window to add individual recipients.
  • For more, select Address Book, highlight the contacts you want, and press Write. Switch the "To" by each name to Cc or Bcc.

This article explains how to send carbon copy(Cc) and blind carbon copy(Bcc) emails in Mozilla Thunderbird using the Cc and Bcc fields and Thunderbird's contacts menu.

Email a Few Recipients

You can add Bcc, Cc, or regular To recipients in two different ways, and the one you choose should depend on how many addresses you're emailing.

To email just one or a few recipients using the Cc, Bcc, or To field is easy.

In the message window, you should see To: off to the left side under the "From:" section with your email address. Input an email address into that box to send a regular message with the To option.

To add Cc email addresses, just click the box that says "To:" on the left, and then choose Cc: from the list.The same concept applies to using Bcc in Thunderbird; just click the To: or Cc: box to change it to Bcc.

If you enter multiple addresses separated by a comma, Thunderbird will automatically split them into their own "To," "Cc," or "Bcc" sections in their own boxes below each other.

Email Lots of Recipients

To email several email addresses at once can be done through the Address Book in Thunderbird.

  1. Open your list of contacts from the Address Book button at the top of the Thunderbird program window.

  2. Highlight all of the contacts that you want to email.

    You can choose multiples by holding down the Ctrl button as you select them. Or, hold down Shift after you choose one contact, and then click again further down the list to automatically select all the recipients in between.

  3. Once the desired recipients have been highlighted, click the Write button at the top of the Address Book window.

    You can also right-click the contacts to choose Write, use the Ctrl+M keyboard shortcut, or navigate to the File > New > Message menu item.

  4. Thunderbird will automatically insert each address into their own "To:" line. At this point, you can click the word To: off to the left of each recipient to choose whether to change the send type to Cc or Bcc.
