I have the opposite complaint, Fastmail marks my bank receipts as Spam, but I don't mind at all.
My bank probably is dumb enough to send newsletters, promotions and other spam-like mails next to notifications, statements and other not-spam-like mails from the same sever, also, Spanish is like a third-class citizen over the Internet, so I got accustomed to the language barrier.
