Christmas E-card 一問

Our company wants to send X'mas e-card to our clients, please me know
whether can find the links? As I had searched lots of the links, but both of them
needs to register as a member and not direct mail to the email address. Most of them need to click into their website for withdrawal the e-card.

Do anyone knew the free e-card function and can show the e-card into the email
without any clicking.

Please help!! Urgently!!

Best wishes!!

Merry Christmas and happy new year!!!
