What type of files can be utilized for bulk email updates in DocuSign?

Bulk email updates in DocuSign require data to be processed in a structured format, and CSV files are particularly suited for this purpose. CSV, or Comma-Separated Values, is a file format that uses commas to separate values, making it easy to structure data in rows and columns. This structure allows for straightforward import and manipulation of data, which is essential for managing bulk actions like updating email addresses across many contacts.

In the context of DocuSign, when performing bulk email updates, the system expects a list of records, typically in a way that can be easily parsed and understood by the software. CSV files are widely supported and provide a universally accepted method for data interchange, making them ideal for use in various applications, including those for bulk updates.

Other file types like TXT, PDF, and XLS do not meet the specific structural requirements for bulk updates in the same way that CSV files do. TXT files typically contain unstructured text data, PDF files are primarily designed for static document presentation rather than data manipulation, and while XLS files (Excel spreadsheets) can hold structured data, they are not natively supported for bulk operations in the same way that CSV files are. Hence, CSV files are the best choice for this type of task in Docu
