Adobe Send for Signature vs. EchoSign or eSign

I just want to know, is the Adobe Send for Signature plan for $1.99 a month the same as having access to the Adobe EchoSign services or the Adobe DC eSign services? I ask because I currently have Adobe Acrobat XI Pro and do not want to have to upgrade to Adobe DC in order to use any sort of electronic signature applications. I notice the EchoSign service on Acrobat XI, but the name has since changed to eSign. Please just let me know if I can download the Send for Signature plan and have access to the same features.

Thanks!
