A window envelope already eliminates one step from your mailing workflow: the recipient's address shows through the clear poly-film panel directly from your document, so you never print or label the envelope face. Custom window envelopes eliminate a second step: your return address, logo, and brand treatment are printed directly on the stock before the envelopes even arrive at your office. Every piece that goes out in a mailing run is already branded, already addressed at the recipient end from the document, and ready to seal and send. At Business Envelopes, we carry custom printed window envelopes in #9, #10, #11, #12, and #14 sizes, across tinted and plain stock, with gum flap, peel and seal, and self-seal closure options. Free shipping on every order.
Custom Window Envelopes With Logo: What Gets Printed and Where
The address window sits on the lower left of the envelope face. Custom printing occupies the upper left: your company name, return address, and logo. That's the standard layout, and it's what the vast majority of businesses running invoices, statements, and client correspondence use. What you put in that upper left panel is entirely up to you. Common combinations include:
- Company name, street address, city, state, zip
- Logo above or beside the return address block
- Tagline or department name beneath the address
- Mailing indicia or bulk mail permit block for pre-sorted mailings
- Phone number or website alongside contact details
Printing goes directly on the envelope stock, not on a label applied to it. That distinction matters for two reasons. Labels can shift in transit, peel at the edges, or leave adhesive residue on postal sorting equipment. Direct printing on stock holds through handling, looks sharp under all lighting conditions, and won't cause a machine rejection at the postal facility. A PDF proof comes back to you before any production begins, and nothing runs until you've approved the layout.
Window Envelopes With Logo: Sizes and Configurations
#10 Window Envelopes, White Gum Flap
The standard for business correspondence. Measures 4 1/8 x 9 1/2 inches, fits an 8.5 x 11 sheet tri-folded with the address block landing in the window. Available with custom logo and return address printing. Gum flap for traditional moisture-seal closure.
#10 Window Tinted Gum Flap
Same format with a security tint interior that blocks document contents from showing through the paper body when held to light. Right choice for invoices, financial statements, and any correspondence where privacy beyond the window panel matters. Custom printing on the exterior face.
#10 Window Tinted Self Seal
Security tinted interior with a flip-and-stick self seal closure. No moisture required. For billing teams and statement operations running high-volume monthly runs where sealing speed and consistency are both priorities. One of the most ordered formats in the custom window lineup.
#10 Window Tinted Peel and Seal
Tinted security lining with a peel-and-seal closure instead of flip-and-stick. Both self seal types eliminate moisture, but peel-and-seal uses a protected liner that prevents pre-activation during storage. The better choice when envelopes are stocked before use rather than processed immediately after loading.
#9 Window Envelopes Gum Flap
Slightly smaller than a #10 at 3 7/8 x 8 7/8 inches. Fits inside a standard #10 outer envelope, making it the standard format for return and reply envelopes included in outgoing mailings. Custom printing for pre-addressed return mailers used by billing departments, nonprofits, and membership organizations.
#9 Window Tinted Gum Flap
Same #9 return envelope format with security tint interior. Used when the return piece carries sensitive payment or personal information that shouldn't be visible through the paper during return transit.
#11 Window Envelopes Gum Flap
Larger than a #10 at 4 1/2 x 10 3/8 inches. Fits a standard letter with a check or a multi-page document alongside a cover sheet. Used by legal offices, financial services firms, and accounting practices that regularly mail document sets that don't fit cleanly in a #10.
Custom Business Envelopes With Window: How Alignment Works
The address window on every envelope in this category is positioned to align with standard document address blocks. For #10 envelopes, the window measures 1 1/8 x 4 1/2 inches, placed 7/8 inch from the left edge and 1/2 inch from the bottom. That's the industry-standard position built into every major billing and accounting platform. QuickBooks invoices, Xero statements, FreshBooks billing documents, and standard Microsoft Word letter templates all put the recipient address block in the same position on a tri-folded 8.5 x 11 sheet. The window catches it without any margin adjustment.
For #9 return envelopes, the window aligns with the address fields on standard reply cards and return stubs. For #11 formats, the window position accommodates the slightly wider document format used in legal and financial correspondence. You don't need to reformat your existing document templates to use any of these envelopes. That's the point of standardized window placement, and it's why these envelopes drop into existing mailing workflows without a setup period.
#10 Window Envelopes With Printed Return Address: Custom vs. Pre-Printed Stock
Pre-printed window envelopes with your return address and logo are the right choice for any organization with a consistent outgoing mail identity. Every piece in every mailing run carries the same branding without anyone in the office manually applying labels or running envelopes through a separate printer before stuffing them. The brand is on the envelope before the envelopes arrive, and it stays consistent across every reorder because the artwork is on file.
Blank window envelopes make sense for organizations that print addresses in-house, manage multiple return addresses across locations, or need flexibility in what appears in the upper left corner. Both options ship free with no minimums. If you need both for different mailing programs, there's no requirement to consolidate.
