We used Salesforce Marketing Cloud for our field sales team to communicate with prospective and current customers. It helped close the loop on site visits, calls, etc. The team had dedicated templates that were easily editable to plug in specific customer info and details. We also used dynamic content to help serve the relevant info and content related to the customer's point in the buying journey. We were able to use the analytics and reporting offered by the platform to track performance on open rates, CTR, bounce rates, etc.
