Salesforce Marketing Cloud

Salesforce Marketing Cloud is a massive enterprise-level platform for large B2C companies. It offers unparalleled scale, deep personalization using Salesforce Data Cloud, and a powerful Journey Builder for orchestrating complex cross-channel customer experiences. Its email studio is just one component. Implementation and management require dedicated resources and expertise, making it unsuitable for SMBs.

It ranks here for its sheer power in the enterprise space, where budget is less constrained and the need for integration with a massive CRM ecosystem is paramount.
