Qualified electronic signatures are a bit stronger than "SMS and up": from your own Wikipedia link, "a qualified electronic signature is an advanced electronic signature with a qualified digital certificate that has been created by a qualified signature creation device (QSCD)". It mentions 3 requirements right after that sentence (like "data used to create the signature is under the sole control of the signatory").
As such, DocuSign is unlikely to be valid as a qualified electronic signature in Germany or other European countries.
