Create an eCard and send it to yourself. Make sure it looks the way you want it to because you can’t edit it once you’ve sent it.
Go to eCards > Sent Cards at the top of the screen.
Find the eCard you created and want to post and click its ’Copy Link’ button. A URL with a direct address to view the card will be copied to the copy buffer.
Go to the social channel where you want to share and paste (ctrl+v) into the sharing window. Note: Not all social media allows you to share a URL. (You cannot share an eCard as an image, on social channels that require an image like Instagram or Pintrest.)
Method 2. Social Sharing buttons on Sent eCards
Follow the above instructions to find the Sent eCard you want to share, and select "View/Share Card" from the options drop-down list.
At the top of the screen are easy share buttons for Facebook, LinkedIn, GooglePlus and Twitter. Select the channel you want to post to and follow the on-screen instructions.
