You are correct that there is no general email support option, however we do offer a live chat option for reaching support teams that you can use as an alternative to placing a phone call. You can reach support through chat by clicking on the "Product Support" link at the bottom of our United States homepage.
You may need to manually change your region at the top of the GoDaddy homepage to "United States-English" in order to see the chat option.
You need to make sure you're on the United States version of the site. Please try using this link and then click on the "Product Support" option at the bottom of the page:
