+ 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).
