Oh yes, sorry I wasn't clear. I ordered the Vive winter bundle. I used guest checkout, so there isn't an account attached through which to change the email (I only made this account to ask the question).
I've gone ahead and created a gmail account using the messed up address since it didn't actually exist before, so I should get any future messages. Mostly I'm just concerned that the system sent an important email that bounced because of an (at the time) invalid address. If that it isn't the case, then no worries.
