I've seen this issue brought up a few times in the past few years, but have not seen a definitive answer. Looking for any sort of integration to generate CTR heat maps (see format below) for our emails. I know that Marketo has the Link Activity Report, however we are hoping to be able to present the data visually.
RCE has a click data option, but it's not visual like that.
I haven't heard of a tool to extract this data and create it. I wrote a short guide to pulling this data from the ELP report and then reconstructing it manually on an image.
