When viewers buy, rent, or subscribe to your Vimeo On Demand title, they can register to receive updates from you via email. You can use those updates to share more information about the title they’ve purchased, send along supplementary materials, or simply to promote whatever your new hotness is.
To get the addresses of anyone who’s sign up, head to the Audience tab of your VOD Settings. From there you’ll see an “Export email addresses” button. This lets you download a .CSV file of email addresses from anyone who opted into receiving communications from you. (Keep in mind, they can opt in without making a purchase.)
Be sure to review the Acceptable Use Email Policy in your VOD Settings before updating your fans. And please note that for legal reasons, this is only way that sellers are able to get in direct contact with their buyers.
