S.C. Code Ann. § 26-6-195: Service of process to e-mail address by government agency.

Notwithstanding any other provisions in this chapter, a governmental agency may use, in accordance with policies and procedures developed by the South Carolina Department of Administration and as circumstances allow, in order to perfect service of process of any communication, an e-mail address from any vendor, entity, or individual the governmental agency regulates or does business with, or an e-mail address from the agent for service of process of that vendor, entity, or individual. Such communication postmarked by a United States Postal Service Electronic Postmark shall have the same force of law as the United States Post Office certified mail-return receipt requested. The South Carolina Department of Administration shall devise policies and procedures for the use of the United States Postal Service Electronic Postmark in respect to state agencies and operations. These policies and procedures, where necessary, must consider the persons or entities which do not have an e-mail address.
