Hi, i have been searching for way to bulk change email address for large number of domains on Godaddy account, not to do it one by one.
And fortunatelly when you go to domain manager
, there are tickboxes, you can list all your domains at one page and tick all tickboxes. Then mouse over button "Contact", click Manage contacts. Then you may use leave all values as is and only change contact email of your domains. That is nice and saves alot of time.
