Email-to-board
Forward an email to a board and it becomes a card.
Where to find it — Edit board → Email-to-board.
How do I turn it on?
Open a board you can edit, choose Edit board, and generate the address under Email-to-board. Forward or send mail to that address and each message arrives as a card.
What becomes the card?
The subject becomes the title, the body becomes the description, and any files are added as attachments. You can pick which list new cards land in.
Is the address private?
Yes. Anyone with the address can create cards on the board, so only board editors can see it. Generate a new address at any time to revoke the old one.
