Having an audit log of access (both email and IP address) is extremely useful if someone asks "did this person actually perform the e-signature". You can then perform motions regarding whether their email has compromised and, if needed, go to their ISP for IP assignment records to see if their account (mobile or home internet) was assigned to that IP. Docusign being the source of authority for the validity of the original IP<->signature log completes the chain of trust and allows this sort of validity defense to work.
