We're rolling out support for HTML in buyer emails, as of today you can use HTML code in the Common Thank You Email settings (located in the Edit Preferences screen). This means you can now display images, clickable banners or even product buttons in the Common Thank You Email message.
On our Beta Features screen (accessible at https://www.e-junkie.com/ej/beta_features.php while you are logged in) you can also toggle on our new HTML based Sales Notification emails, just click the green "Enable" button to turn them on (or the red "Disable" button to turn them off and receive the normal text-only notification)..
These are a new way to receive updates from our system about your sales and include a link to your transaction log for that particular purchase.
