What type of mail includes insurance for document reconstruction up to $100?

The correct choice is PMEI, which stands for Priority Mail Express Insurance. This service includes a feature specifically designed to provide insurance coverage for the reconstruction of important documents, allowing for up to $100 in reimbursement. This is particularly beneficial for customers who may need to send valuable or critical documents that could require documentation in case of loss or damage.

Priority Mail and Express Mail are both service options offered by postal services but typically do not include the specific insurance coverage aimed at document reconstruction. Registered Mail is a secure mailing option but is primarily focused on security rather than offering reconstruction insurance directly. Therefore, PMEI is the most relevant choice as it directly addresses the need for insurance related to document integrity and reconstruction.
