Unfortunately, no.
Each Client Manager user login can only support one email address along with its own domain name. This will allow webmail to work properly as it's designed to pull through email information based on the domain and associated email address.
If you have more than one email address where you are receiving emails to save to Client Manager, we recommend you forward those to your linked email address so you can then save them to Client Manager via Webmail.
If you have any questions, please email our support team at cmsupport@openmarkets.com.au
