Gmail Auto BCC

Great idea and so far I have been able to see the CC email address I added, however I am trying to set it up so that my Colleagues must have the same address CC'd and when I add their emails to the "from" option they are not seeing the added email in the cc'd box.

Just added and set this up but not working. I see the "auto bcc enabled" button However I don't see the mail hitting my bcc inbox.

Works great when trying to bcc one email address. when trying to bcc two emails, it separates the emails with a comma and no spaces. As such, they are not formatted properly, and it does not work. Edit: Thanks for the reply! When I BCC two addresses it adds the emails like this: abc@gmail.com,def@gmail.com so there are no spaces and gmail seems to see this as a string of text. If I click on them manually, or add a space, gmail will then put the email in a "bubble" signaling it is recognized as an email address but having to do that manually defeats the purpose.
