Salesforce.com believes in the idea enough to buy them.
At a high level, this is about accepting that most leads are not “hot”, Pardot offers a way to nurture all warm leads and monitor whether they are moving toward cold or hot. If hot, the Pardot nurtures tha relationship in a way most relevant to the lead. They call this Smarter lead generation and effortless email marketing.
