Which of the following is NOT a method for serving a subpoena?

The correct answer indicates that electronic mail is not a recognized method for serving a subpoena. Subpoenas, which are legal documents requiring an individual to appear in court or produce evidence, must be served through methods that ensure the recipient has received the document in a reliable and official manner.

Personal service is a widely accepted method because it involves delivering the subpoena directly to the individual, ensuring that they are informed of its contents. Certified mail provides a similar level of assurance, as it requires a signature upon delivery, ensuring the sender has proof of service. First class mail, while generally less formal, is still an accepted method in many jurisdictions when other specified methods are not viable.

Electronic mail, however, does not fulfill the legal requirements typically associated with formal service of a subpoena. This is because it lacks the required verification and formal acknowledgment that other methods provide. The use of email could lead to disputes over whether the document was actually received or whether it met the standards required by law for serving legal documents. Therefore, it is not accepted as a method for serving a subpoena.
