Which data points are affected by setting up email subscriptions through CSV imports?

Setting up email subscriptions through CSV imports specifically affects how external IDs are treated in terms of data tracking and reporting. When CSV imports are utilized for email subscriptions, the external IDs of users are not counted as part of the overall data tracking for engagement metrics. This means that while the imported data may successfully create or update records, external IDs do not influence the numerical data points often analyzed for performance, such as opens, clicks, or overall engagement rates.

This approach allows for more streamlined and organized data management, where external IDs serve as identifiers but do not contribute to the metrics that organizations monitor for evaluating the effectiveness of their email campaigns. Other data points, such as engagement metrics or subscription statuses, remain unaffected by the import process in the context discussed. This distinction is crucial for ensuring that the integrity of user engagement data is maintained while still allowing for efficient management of user records through CSV imports.
