I do not believe there are GoDaddy logos inside Workspace email? If you're accessing it from email.godaddy.com I believe email.secureserver.net can be used instead?
You can always just not login to Workspace email at all and setup a POP3 or IMAP to access your email. Check out Set up your email address with POP. I hope that helps?
