I thought e-mail was supposed to be quick

I'm getting super frustrated with Best Buy Rewards right now. The platform is not being efficient and quick enough for my tastes. My profile information is out of date, and I really want to change it. I had to create an account, of course. And having created the account, I need to verify my e-mail address. Which would be easy, except the e-mail that the site just sent still hasn't arrived in my inbox. And I've been waiting for about 20 minutes. And it's getting super late, and the odds of me remembering the ridiculous password they made me create are slim to none.
It's now almost midnight, and this is the frustration I'm dealing with way too late on a Tuesday night.
