Problem with subscriptions

Hey Guys!

I just launched my blog on Saturday (season26.com, using the free Adelle theme) and I’ve had some people tell me they’ve subscribed but I didn’t receive any type of notification. I’m using the round cube email server provided through bluehost and assumed I’d get an email letting me know when someone subscribed, but I didn’t. Do the notifications go somewhere else? How can I find out when someone subscribes? I’d like to send them a follow up email and gift.

Thanks,
Jasmine
