First off, you are paying more than you should. You should really take a look at other providers to see what other options you have. Unlike Godaddy, many other hosting companies are unlimited when it comes to how domains can you host on one account, unlimited email account, as much disk space as you need and many other features/software to use for your website.
Go ahead and login to your Godaddy account and review your statement and review what services you have, what they do and how much you are paying for all of it. Now go look at some others, you will be surprised how much you can get for $9.99/month. (No, you can relax I’m not selling hosting.)
