The cost to mail documents through USPS depends on several factors, including the size and weight of your mailer, the mailing class you choose, and the destination. First-Class Mail is often the most affordable option for lightweight documents, while Priority Mail may be better for heavier or urgent shipments. You can use USPS online tools or visit your local post office to get an estimate. Remember, using self-sealing document mailers can help keep your paperwork secure and flat during transit.

USPS does provide certain types of mailers, especially for Priority Mail and Flat Rate services. However, if you need specific sizes or features like bubble padding, rigid protection, or self-sealing closures, you can find a wide selection of document mailers at Walmart.

• Choose from padded, poly, or rigid mailers for different needs.
• Bulk packs are available for frequent shippers.
• Look for self-sealing options for convenience.

To save on mailing costs, consider using lightweight, self-sealing document mailers and sending your paperwork via USPS First-Class Mail.

• First-Class Mail is ideal for documents under 13 ounces.
• Choose mailers that fit your paperwork snugly to avoid extra postage.
• Bulk packs can help reduce per-mailer costs.

Mailing a document with USPS is simple.

1. Place your paperwork in a suitable document mailer—choose padded, poly, or rigid based on protection needs.
2. Seal the mailer securely, especially if it's self-sealing.
3. Address the mailer clearly and add postage.
4. Drop it off at your local post office or mailbox.

Choosing the right mailer size depends on the type and quantity of documents you’re sending.

• Measure your paperwork and select a mailer that’s slightly larger for easy insertion.
• Rigid mailers are great for photos or important papers you want to keep flat.
• Padded mailers offer extra protection for delicate items.
• Poly mailers are flexible and lightweight for bulk shipments.
