​@ArunaKunda Embedded sending is the act of creating and sending the envelope embedded inside of a custom application. For example you might want to send envelopes from your website instead of navigating to Docusign. You can embed the Docusign user interface into your website and allow sending envelopes directly from your website. 
 

Embedded signing is the act of signing instead of sending.

The benefit of embedded signing and embedded sending is that it can allow end users to send and sign anywhere without needing to login to an email to sign, or login to Docusign directly in order to send.
