    Docusign has a .com address, def not a .click address. This is 100% fishing. A very easy way to tell is to hover over any url and see what the address is. You can also try to do a reply, or if your savvy enough look into the routing info of the email. Did it com from the companies domain? I.e. docusign.com, fedex.com, ups.com anything like that. If it didn't, its fake. Source: over 3 years ago
