If you have RCE, you can get much of the email data.
You won't get a click heat map, however. I would consider running your data through another tool or perhaps just using Link Perf Report to construct a rough map. I wrote about this type of report in the original Marketo Guide.
But honestly, what are you really hoping to do with this? There is already a ton of free data showing eye tracking and most common areas people are drawn to on an email. And the heatmap will really just reflect your design, rather than what people do. Your design should take advantage of what people do.
Email principles are more powerful:
- Keep critical info in the Subject Line and top 1/3 of email so that people will see the preview.
- Date, Time, Location can be in the subject for events. Repeat it throughout the email.
- Post map info in the email too.
- Get the point quickly.
- use images sparingly and with ALT tags
- avoid HTML colors
- Repeat the CTA as a button and as Text at least twice.
- supposedly pix of presenters help.
- stop using those giant top banner images with no info. No one likes those.
