If enabled by the Package creator, for all types of Packages, you can review the documents to be signed before signing them.
If the Review Documents option was turned ON, the email notification sent to all signers would include a Review Documents link, clicking on it takes the signer to the Review Documents page.
On this page, you can request a link to the Documents. To verify the requester's identity, you will need to enter a valid email address (only signers in the Package can access the documents) and click on Request Link.
A secure link is sent to the entered email to review the documents.
Clicking on the link opens the original version of the document for review.
Entering an invalid email would result in an error, and the request would not be completed.
