Mich. Comp. Laws § 600.1332
The clerk, jury board, or sheriff shall summon jurors for court attendance at such times and in such manner as directed by the chief judge or by the judge to whom the action in which jurors are being called for service is assigned. For a juror's first required court appearance, service shall be by a written notice addressed to the juror at the juror's place of residence as shown by the records of the board, which notice may be by ordinary mail or by personal service. For subsequent service notice may be in any manner directed by the judge. The officer giving notice to jurors shall keep a record of the service of the notice and shall make a return if directed by the court. The return shall be presumptive evidence of the fact of service.
