I would like to BCC Trello when sending external emails, and at the same time to add private comments to my related card, which will not appear in the subject or the body.
Is that possible somehow?
EDIT: Maybe I can add my custom text inside the address in the BCC? This way instead of "<username>+<hash>@boards.trello.com" I will use "<username>+<hash>+<custom_text_to_get_into_the_card>@boards.trello.com". (Maybe it can be at least a nice feature-request?)
