If you want to change the email address of the account owner, go to My Account page and under Details update the email address:
Then hit "Save Changes". You will notice a green message saying: Your account information has been updated successfully!
After email change submit, the new email address should get an email with a link to click on. Only after clicking on that link change is done. The old email address will get a Notice of Email Change.
These are the steps to change the main email address. In order to switch the ownership completely, please contact us to facilitate this process.
