There are strong electronic signatures which are as safe as a signature can be: iow, a question of who generated the key (an issue with keys provided by official cert authorities) and how is it kept safe at rest (basically, how much care a user takes of them). DocuSign is, in general, neither of these. I am sure there are less convenient options with DocuSign than the email based one, but I've only ever been asked to "sign" by attempting to draw my signature using a mouse or their own font. I'd rather have someone attempt to forge my handwriting which experts can usually detect, and which requires a bit more sophistication: my concern is not about them being validated, but that instead if I claim how that's not my signature, I can easily provide a bunch of past signatures to an expert to prove my point. There are free software and free hardware tokens which can generate secure certificates to use for encryption or signing. I would probably trust those best.
