Yes, you can change your email address in your article's metadata at any time up to publication. However, if you do change your email address in the metadata, please contact support.
All authors are emailed a License to Publish form during the publishing process. This form is sent to the original email address you provided during submission. If you change your email address, the form is still sent to the original email address, which may cause you to miss it. For this reason, please let support know when changing your email address in the metadata so that they can send the License to Publish form to the correct address.
