What action should a marketer take before implementing large data set imports?

Ensuring that data is structured appropriately is essential before undertaking large data set imports. Proper data structure facilitates seamless integration into the marketing platform, allowing for efficient processing and reduced risk of errors. When data is organized correctly with consistent formats and clear definitions (such as matching field names and data types), it helps avoid issues during the import process, such as duplication, misalignment, or data corruption.

In contrast, limiting the number of files included or consolidating all data into a single file may not specifically address the structural integrity of the data itself. Additionally, using a slower, more manual process does not provide a strategic advantage and could lead to inefficiencies. Therefore, prioritizing data structure before importing ensures that the entire operation is as effective and error-free as possible.
