Tex. R. Civ. P. 109a
Whenever citation by publication is authorized, the court may, on motion, prescribe a different method of substituted service, if the court finds, and so recites in its order, that the method so prescribed would be as likely as publication to give defendant actual notice. When such method of substituted service is authorized, the return of the officer executing the citation shall state particularly the manner in which service is accomplished, and shall attach any return receipt, returned mail, or other evidence showing the result of such service. Failure of defendant to respond to such citation shall not render the service invalid. When such substituted service has been obtained and the defendant has not appeared, the provisions of Rules 244 and 329 shall apply as if citation had been served by publication.
