Can someone explain the difference?

DocuSign is a publicly traded company that offers a product in which you can send documents and their process complies with the E-Sign Act.

Thank you!!

Don't forget about the little old UETA:

Operationally, UETAs are basically "ESIGN-Lite" (unless something's changed in recent years.) If a product like DocuSign supports full compliance with ESIGN's informed demonstrable consent process for e-document delivery, the same process automatically complies with the UETAs.
