Shared E-mail...claiming prizes?

So, am I to understand it's OK to have my account under a shared E-Mail with my girlfriend? She doesn't have a covers account. The e-mail is officially listed as hers. Just wanna make sure, on the extremely unlikely chance I win something, I don't get disqualified on a 'technicality. Thank you in advance for any info on this matter

Why not just get your own email?  (insert whip sound here) 

im shocked its under her name and not yurs. she sounds cool and fun. (replace that with fat and a nutcracker) now go erase yur browser history.
