Obviously, the output of the marketing automation system should be an input to the CRM system. But that linkage should be only for those leads that are really ready to be qualified—typically well below 10 percent of the total stored in the marketing automation system. Even the leads that have not survived qualification or have simply lost interest should be hidden from the sales team – they’re just clutter and an unpleasant reminder about someone who wasted their time.
Marketing automation plugs into a company's CRM system, which, typically, has its own native marketing automation cloud service (such as Salesforce Pardot and Oracle Eloqua). Eloqua will work with other CRM platforms that compete with Oracle's, and Marketo, an independent marketing automation platform, will work with Salesforce, Oracle, Microsoft and other CRM systems. HubSpot also is a popular marketing automation platform that has its own CRM backbone.
