How To Change Email Address

You can easily change the default email address that is used to send all emails from. 

Simply log in to your main user account and hover over the "My Account" tab and click "Manage Users":

Under "Account Details" is the login credentials. Click the green pencil to the right of the main user to view and/or change the email address. 

An "Edit User" area will open up where you can change the email address.

You can then eliminate whatever the current email address is and enter the new email address and then click "Update" at the bottom. 

By doing this, it actually changes the default "from" email throughout the entire account unless you have a custom email set up.

If you don't have any idea yet of the custom email set up, you can visit this article to learn more about this topic:
