Christmas e-card required for Company use this year

My company wishes to send out an e-card this Christmas instead of the traditional cards through the mail.

We require an animated e-card to be designed so we can send this to our customers wishing them a Merry Christmas.

This needs to be visible when they email opens rather than clicking on a link to view the message. The card needs to follow a traditional Christmas theme and have a message from my company.

We will need to see a previous example of your work

Only one e-card is required, this will be sent out to our customers individually once we have received it
