Why isn't my facebook confirmation email being sent?

[Once-Ler]

So I wanted to make an alternate facebook account to marry it on my main and also to send game requests, and in order to do that, I had to make a new email.

But the confirmation email has not arrived in my yahoo inbox. I checked the email I had typed into facebook to create my account, and it does match the one I made in order to create it. Also, I resent the confirmation email like 4 times and it still didn't come. And I keep refreshing my yahoo inbox and it still hasn't shown up.

This is important because without confirming my email on my facebook account, I can't access games for game requests.
