I have added a new feature to the next WebCards release: HTML email notifications.
Through the admin centre you can choose to send your notification, reminder and acknowledgment emails in HTML or plain text format.
Many users had been requesting the ability to send HTML emails and making it optional gives you the best of both worlds.
You can test out the new email format over at the WebCards demo version.
Let me know if you have any comments or encounter any errors using HTML emails.
