How do I access my GoDaddy email account in my iPhone?

You are asking a lot. While we cannot predict what problems you may encounter, let alone explain how to overcome all possible issues … I can offer these instructions on how to manually or automatically add an email account to the Apple Mail icon. If you run into problems during the process, you should contact GoDaddy for trouble shooting. Many have used these instructions to successfully connect other email carriers to the Apple Mail app, including AOL, Gmail, Yahoo mail, etc. If you run into specific issues during the process, we invite you to come back with a detailed explanation of what’s happening. We may be able to help then.

On a side note, I did not see a GoDaddy mail app in the Apple App Store. But if you cannot connect GoDaddy to the Mail app, you may be able to use Safari to go directly to the GoDaddy email web page.

I hope this helps.
