Due to a request from Microsoft, we have changed our OutlookCast feature to a new name and new email addresses. If you wish to compose emails in Outlook or any other email program, and send them to an email address that is set for each of your marketing lists, you will need to begin using the new @inboxcast.com address. To do this, please open the marketing list and click the OutlookCast button (this will be re-labeled to "InboxCast" in our current release), and use the new email address. We apologize for any inconvenience.
For more details on using InboxCast, see our help article here: http://help.clickdimensions.com/send-outlookcast-email/
