We are trying to use GIF in our mail.But the problem is that some outlook version does not support GIF's.How can I do a fallback to a png-file when a customer is open the email in outlook?
Outlook 2002 supports GIF but 2007 to 2016 does not.
Here the conditional code which you can use to use an animated GIF for the 2003 version but a static version for the others.
<!--[if mso 11]><!--> <!--- Code for OutLo0k 2003-->
<img class="outlookcomIMG" src="ANIMATED.gif">
<!--[if gte mso 11]>
Let me know if this works.
