If you would like to use an RSS feed to automatically populate a Mailchimp newsletter with products or features, there is a known error. The coding Mailchimp provides will display the images in Gmail, but not in Outlook. To fix this issue, please correct the coding provided by Mailchimp as follows:
The original coding provided by Mailchimp reads:
<img src="*|FEEDITEM:ENCLOSURE_URL|*" style="width:600px !important;" />
(emboldened text added to emphasize area that requires a change)
This coding is what creates the issue. To resolve it, simply delete the "px" from the emboldened portion of the above coding. Your new code should read:
<img src="*|FEEDITEM:ENCLOSURE_URL|*" style="width:600 !important;" />
This coding will resolve the issues, and images should display properly in Outlook once the coding has been corrected.
