What can be added to a send log once configured?

When you configure a send log in Salesforce Marketing Cloud, it is designed to capture specific information about emails sent to subscribers. One of the key capabilities of send logs is the ability to add new custom fields. This allows marketers to tailor the data collected in the send log to their specific needs, enhancing the context of engagement metrics and allowing for more granular reporting. For instance, if there are additional characteristics or attributes about the subscribers or the email campaigns that are important for analysis, creating custom fields supports capturing that relevant information effectively.

The flexibility to add new custom fields allows organizations to ensure they collect the precise data they need as their marketing strategies evolve, thus enhancing the effectiveness of their campaign analysis over time. This adaptability is critical for optimizing email marketing efforts and improving customer relationship management.

In contrast, engagement metrics or historical data are generated through the interactions that occur during the email sends, while test send results from Content Builder provide insights during the content creation phase but don't get integrated into the send log in a configurable manner.
