Seven Types of Data Extensions We Use on SFMC Projects
The article discusses seven types of Data Extensions (DE) used in Salesforce Marketing Cloud (SFMC) projects. Each DE type has distinct behaviors and requirements, which are crucial for effective email campaign management. Understanding these types helps prevent common mistakes, such as sending emails from non-sendable DEs or using outdated Filtered DEs.
- ▪Sendable DE is the primary type used for sending emails and must meet specific requirements.
- ▪Filtered DEs need to be refreshed to reflect the current state of the source DE, as they do not auto-update.
- ▪Shared DEs allow multiple Business Units to access the same reference data without duplication.
