Yes, you can. Simply add the email address that never receives spam to your Allow list. Add it as a word that appears in your headers and not as an email address.
To access your Allow list, select the Allow/Block List button in the toolbar. Select the Add button. Type in your email address. Highlight the pulldown menu and select Word that Appears in the Header. Click "Ok".
You can also add other information that appears in the headers, such as IP addresses of servers. This is particularly useful if you have a company email server and you want to automatically receive any mail from that server.
If your company ISP tags mail as spam at the server level you can add these tags to the Block list if you want SpamBully to filter those messages automatically.
Be careful when using these options as it can cause too much spam to get through if you add something to your Allow list that is also common in spam messages.
