Personalize Branding

Custom window envelopes display the recipient’s address through a transparent window, so businesses no longer need separate address labels. As a result, offices can prepare business mail more efficiently. Companies commonly use these envelopes for invoices, billing statements, payroll checks, and other routine correspondence.
In addition, many businesses print a return address or company logo on their envelopes to maintain consistent branding across outgoing mail.
Most window envelopes come in standard sizes such as #9 (common for reply mail) and #10 (standard business size). Because these formats match common letter layouts, addresses align correctly within the window when documents are folded properly. Furthermore, custom printing and window placement options allow businesses to tailor envelopes to their specific mailing requirements.

What Are Custom Window Envelopes?
Custom window envelopes are envelopes designed with a transparent window that displays the recipient's address printed on the document inside. When documents are formatted correctly, the address appears through the window automatically, removing the need for separate address labels.
They are commonly used for business mail such as invoices, billing statements, payroll checks, and other routine office correspondence.
Many businesses choose to print window envelopes with a return address or company logo. Printed envelopes help maintain consistent identification for outgoing mail and can simplify mailing preparation by eliminating the need for separate labels or stamps.
Window envelopes are available in several sizes and window placements so they can align properly with standard document formats.

+ Can I print my logo or custom colors on window envelopes?
Yes — and this is where your envelope becomes part of your brand. You can customize window envelopes with black ink, full-color printing, logos, return addresses, and branded design elements. Whether you want a clean professional look or bold brand visibility, we print to match your visual standards.
+ Will my address align correctly?
We provide standard window placements aligned with USPS mailing specifications. Templates are available to ensure your document folds position the address properly within the window.
+ Do I need a security tint?
If you’re mailing invoices, statements, or financial documents, privacy matters. Security tint prevents sensitive information from being visible through the envelope, protecting your clients and your business reputation.
+ What seal type should I choose?
- Gum seal – Traditional and cost-effective for standard mailing operations.
- Self-seal – Faster processing for bulk mailings and high-volume environments.
The right seal impacts both workflow efficiency and cost control:
+ What size window envelope fits a tri-fold letter?
A standard 8.5" x 11" letter folded into thirds (tri-fold) is designed to fit inside a #10 window envelope — the most common format for invoices and business correspondence. When your document is formatted properly, the address aligns with the standard #10 window placement for accurate, machine-readable mailing.
+ Are window envelopes USPS compliant?
Yes — standard #9 and #10 window envelopes are designed to meet USPS mailing requirements when used with properly formatted documents. Window size and placement follow industry specifications to ensure the recipient address is clearly visible and machine-readable. To avoid mailing issues, always use the appropriate document layout and verify alignment with a proof before printing.
+ Can I customize window placement?
Yes — especially if your document layout doesn’t follow standard formats. While most businesses use standard window positions for compatibility, we offer dozens of specialty window configurations and can custom-manufacture window placement to your exact specifications (starting at 2,500 quantities).
