Salesforce extremely supports digital marketing, to understand it, you first need to know about the Salesforce marketing cloud because marketing cloud allows us to talk individually with the customer and also creates the one to one relationship like we have in stores.
Now, clear your confusion that the digital marketing is a type of online marketing. It means its main activities are Email campaigns and paid advertisements among the others. Salesforce CRM is much more than digital marketing.
Or in the other word we can say that Salesforce supports digital marketing through its marketing cloud among other cloud services, and provides many more services. So please eliminate your confusion between the two.
Note that Salesforce (CRM) is a “Customer Relations Management” platform which has the Service Cloud, Marketing Cloud, Sales Cloud, Analytics Cloud, etc. as its core services and many more cloud services in its SaaS offering.
