What type of receipts may be filed electronically as proof of service by mail?

Filing scanned return receipt cards and national courier service receipts electronically as proof of service by mail is an accepted practice because these forms provide verifiable evidence that the documents were sent and received. When using certified mail, return receipt cards serve as proof that the recipient acknowledged receiving the documents, while national courier service receipts confirm the delivery of the documents. Both of these receipts can be easily scanned and submitted electronically, which aligns with modern practices that promote efficient documentation and record-keeping in legal processes. This method reduces paperwork, making the process more streamlined while maintaining the necessary legal standards for proof of service.
