Yes. When you post an eCard on social media websites, you do not have as much detail as to who is picking up your eCard like you do when sending an eCard to an individual email address. You will, however, still see how many times it was viewed by clicking on the button for 'View Card'. Each view, for which we cannot identify the recipient, will be marked as ’anonymous.’
Tip: In your ’sent cards’ bin, you can add comments to each eCard. This will help you remember the delivery method you used such as Facebook or LinkedIn and any specific notes as to why you posted it. Only you can see these notes.
