In this blog, we’ll evaluate four leading platforms against a set of criteria for a B2B business that uses Salesforce to help you make an informed choice. 

We won’t include Pardot in the comparison because it is, well, terrible and hasn’t evolved in years…


Before diving into each platform, let’s outline the key requirements for our evaluation:

  • Salesforce Integration
  • WordPress Integration (e.g. via Gravity Forms)
  • Email Building Capabilities
  • Campaign Types (Newsletter, Autoresponders, Drip)
  • Tagging and Segmentation
  • Social Media Integration
  • Live Chat Features
  • Data enrichment
  • LinkedIn integration
  • User Event tracking
