Which of the following is NOT considered a way to serve a summons, according to Arizona guidelines?

Mailing a summons to the respondent's address is not considered a valid method of service according to Arizona guidelines. In Arizona, personal delivery methods are emphasized to ensure that the individual receiving the summons is fully aware of the legal proceedings against them. Options such as personal delivery by the sheriff, service by a constable, and service by a private process server are all recognized methods of properly serving legal documents, as they involve direct contact and confirmation that the summons has been received by the respondent. This direct approach helps to uphold the integrity of the legal process and ensures that defendants are informed of their rights and obligations in a timely manner.
