We had an issue with our email newsletter that we sent out on 1/10. Due to caching, it served the wrong ad to some of our users who were using a customized google platform. Our ad serving company did provide us with some extrra coding as a temporary fix for the Gmail issue of Google’s image serving policy change., but we need additional help
Can anyone help in figuring out how to include scripts or strings in Marketo email templates that include sequential numbering or unique random generators for ad unit cache busting?
I can provide the code we are using if that's helpful.
