With the SMS Platform enabled on your CRM account, you can send E-Signature requests via SMS text message. For more information about sending E-Sign requests please review the Generating and Sending Documents for Signature article.
To send an E-Signature request via SMS, simply enable the "Send SMS" option while configuring your E-Sign message.
If the contact does not have a Cell Phone Number, the "Send SMS" option will not be available.
After clicking Send For Signature, the system will send an SMS E-Signature request in addition to the Emailed E-Sign request.
