Hello, 

Thank you for reaching out here in the DocuSign Community. 

Bulk envelopes are just separate envelopes of the same document sent to different people, therefore, they can only be downloaded one by one. There is a product that DocuSign offers that has an additional cost that would allow you to download the documents at once, if you are interested, please create a Customer Support case or contact our sales department.

For more technical information on Retrieve: https://support.docusign.com/s/document-item?bundleId=oyh1657217277873&topicId=lfc1606331700617.html&_LANG=enus
