Link Building Outreach Platforms Compared

I came across this article this morning - http://pointblankseo.com/outreach-platforms​ - regarding link building outreach platforms. Clearly some of the functionality of these tools, Marketo does not have (nor do I expect it to). But there are email functionalities noted where if you had a list of prospects, etc. the email process probably could be done through Marketo. Is anyone using Marketo for outreach efforts (specifically link building efforts) not associated to lead generation activities? If so, I'd be interested in your process.
