Landing Page Rendering Different On Different Internet Clients

IE is notoriously difficult to work with.  Do you have a link to the landing page to see what exact problems you are experiencing.  Have you tried viewing it with other browsers besides chrome and ie? Did you use marketo's landing page builder or did you build your own?

Spacing/rendering problems are generally cross-browser issues related to the absolute positioning that Marketo's landing page WYSIWYG editor employs.

I have run into similar cross-browser spacing problems between Chrome and Firefox.  If you have someone code-savvy on hand, our fix was to apply some browser-specific CSS to our landing page templates, to help correct the rendering discrepancies.

Here's a StackOverflow thread that steps through how to do this for different browsers, including IE and Firefox:

Hi Stephen,
Building a landing page in Marketo is like building a page in a website using HTML and CSS code.
Developpers use to test their page on all browser once created to see how it displays.
I tend to agree with John above, IE is the worst one for rendering.
