Is there always an email for an unsuccessful bid? I'm at about T-48 with no rejection email yet. The confirmation email from a few weeks ago did not promise notification, so is it possible that no notification will ever come? I'm 99% certain that my bid will be unsuccessful, so now I'm just wondering when I'll find out.

[UPDATE: A few hours later, I got the email: "Unfortunately your bid to upgrade to SWISS First Class for your flight below was not accepted this time." As I said above, I was nearly certain that my minimum bid wouldn't go through (F1 on a route with strong premium traffic), but I am pleased that there was notification of that fact. I'll be fine in my throne seat, alas!]
