I use GoDaddy for my business email domain, and Hushmail for encryption; do GoDaddy and Hushmail count as "management and admin" business expenses?

It depends. If you use your website or email services primarily for advertising, you can claim the fees as an advertising expense. 

Otherwise, you can enter these expenses as Other Expenses, or if you pay a monthly fee, you can enter them as Licenses, Business Taxes or Dues.
