Envelopes

Make every piece of mail pop with JAM Paper. We offer an unmatched rainbow of colors, finishes, and sizes to help your mail stand out, including wedding invitations, holiday cards, thank-you notes, and creative business correspondence.

Ditch boring mailings and express your personal style. Explore hundreds of shades, from rich jewel tones and soft pastels to vibrant neons and classic neutrals. Choose from tactile finishes like smooth vellum, classic linen, natural kraft, and shimmering metallics that add a custom touch to any occasion.

Find the perfect fit for whatever you're sending. We carry an extensive selection of standard invitation formats (A2, A6, A7, A9), square envelopes, everyday #10 business sizes, and large 9x12 catalog mailers. They’re all available in small packs for personal projects or bulk packs for larger events and office supplies.

Complete your look with your choice of contour, modern square, or traditional commercial flaps. Use convenient peel-and-seal strips for quick self-adhesive mailing or moisture-activated gumming for high-volume invitation assembly.

Some envelopes are designed for shipping fragile items. These envelopes often have additional padding or cushioning material to protect the contents during transit.

While padded envelopes are commonly used for shipping small items or fragile objects, they can also be used to ship important documents. However, it's recommended to consider using a document mailer or protective sleeves to ensure the documents remain flat and uncreased.

There are envelopes specifically designed for use with automatic envelope-stuffing machines. These envelopes have features like open-side construction and smooth surfaces to facilitate automated processing.

Some envelopes are designed specifically for mailing bulky items. These include gusseted envelopes or expandable envelopes, which have pleated sides that expand to accommodate thicker contents.

Window envelopes have a transparent window on the front that allows the mailing address to be visible without having to write it separately. They are commonly used for invoices, statements, and other mailings where the recipient's address is printed on the enclosed document.

You can use online postage calculators provided by postal services or consult the postal rates and regulations guides. These resources will help you determine the appropriate postage based on the envelope size, weight, destination, and any additional services required (such as tracking or insurance).
