If you upload the presentation (like any other file) then you can link to it from any landing page or email for that matter. The borader question would be accessiblilty. I would recommend you convert the presentation into a PDF or post it on some other service like slideshare. This will ensure your visitors are able to view the data (even if they don't have PowerPoint installed).
So to do this, simply upload your document into your design studio and then get the URL and add that as the link.
