Personal jurisdiction is not acquired pursuant to CPLR 308(2) unless both the delivery and mailing requirements have been complied with. Here, plaintiff's affidavit evidencing service at defendant's place of business fails to include any proof of mailing as required by CPLR 308(2), and no evidence of compliance with the mailing requirement is otherwise found in the record. Service was invalid.
