What does "envelope" refer to in DocuSign terms?

In DocuSign terminology, an "envelope" refers specifically to a container for documents that are being sent out for signing. This concept is fundamental to how DocuSign operates, as it organizes and manages the entire signing process for one or more documents, allowing the sender to include relevant details such as the recipient(s), signing order, and any specific instructions.

The envelope encapsulates all aspects of the transaction, from the documents themselves to the metadata that guides the signing experience, such as reminders and expiration dates. This structure helps ensure that the signing process is efficient and secure, as all necessary information is contained within the envelope for both the sender and the recipients.

In contrast, the other options address unrelated concepts. The email format pertains to communication methods, the security feature relates to data protection and transmission protocols, and an archive suggests storage of completed transactions rather than the process of sending documents for signing. Therefore, the correct understanding of "envelope" as a container for documents being sent for signing is critical for utilizing DocuSign effectively.
