I haven't gotten an email from them saying that I applied or that they'll be in touch or anything. That's weird... I think I checked to make sure that my email was spelled correctly?

You may wish to call them and ask if there is anything they need from you. As was previously mentioned, it's often just a verification issue. Ive seen a number of people state they were called by the fraud department to make sure it was them, but they also mention calling Cap One back after a number of days and being approved. If you're worried about seeming pushy, you wont when you word it like the previous poster said, asking if they need anything from you. I've only been mocked(with a different company) after I called a 2nd time, after I think it might have been suggested on here that it was worthwhile, and even that was mild, seems infrequent, and didn't seem to effect the process. WIth that company(AMEX), I had to wait over a week just to be told I needed address verification. This will likely not be the case with Capital One, or the mockery, ugh, lol.
Also, there is another lesser known issue for manual review(vs the automatic, computer generated variety), which may also be a bit less common. If you are on the cusp of a credit limit level, a human being sometimes has to look things over to decide your credit limit. With your scores and income, this certainly is not out of the question. I don't want to elevate your hopes too high by giving hypothetical examples though(like 3k vs 5k vs 10k), so I'll leave it at that.
It could be either, both, neither, a combination of any of those and something else, but I think it's more likely than not at least one of those(verification/credit limit cusp).
If I were antsy at all, I'd give them a ring and ask if there was anything they needed from me. You may need to do so within certain business hours, or may not, but the sooner you call the sooner you will know. Best wishes!
I finally turned 21 today and in the mail came a nice surprise letter from Capital One saying that I had been approved for 10k! An awesome birthday surprise. 
They just needed income verification.
