We Offer Mailing Envelopes In Every Standard Business Size
Our envelope range covers C4 and C5 formats for full A4 and A5 document mailings, DL format for folded letter correspondence, and A2 and A6 sizes for card mailings and promotional inserts. We also produce square envelopes for invitation mailings and larger flat envelopes for unfolded document delivery where crease prevention matters. Custom sizes are available for non-standard mailing formats. Every size we produce is calibrated against standard postal dimension requirements so your mail moves through the postal network efficiently.
Choose Between Kraft, White, And Colored Envelope Stocks
Kraft envelopes give a warm, natural, and honest aesthetic that suits artisan brands, boutique businesses, and brands that want their correspondence to feel personal rather than corporate. White envelopes give the cleanest and most vivid print base and are the most popular choice for corporate and ecommerce mail. Colored envelopes in a brand-specific hue are available for brands that want their mail to stand out in a recipient’s inbox. All stocks are available with either a smooth or a slightly textured finish depending on the brand aesthetic and the print approach.
Print The Brand, The Return Address, And The Campaign Message
We print mailing envelopes in full CMYK for brand logos, return address panels, promotional messaging, and any artwork or photography that forms part of the campaign. A direct mail envelope that carries a compelling visual message on the outside increases the likelihood that the recipient opens it rather than setting it aside. Pantone matching keeps brand colors exact across every envelope in a mailing run. Front and back printing is available for envelopes where the back flap carries a secondary brand element or a campaign message. The return address can be printed as a permanent brand element or left as a variable area for different senders.
Peel And Seal, Self Seal, And Gummed Closure Options
We offer mailing envelopes with peel-and-seal adhesive strips for fast, clean closure without licking or wetting. Self-seal pressure closures are available for high-volume mailing operations where speed at the envelope stuffing stage matters. Traditional gummed closures are available for brands that prefer the classic envelope feel or for contexts where the recipient associates gummed envelopes with formality and official correspondence. Security tinted envelopes with a patterned inner lining are available for document mailings where contents privacy is important.
Direct Mail Campaign Envelopes That Demand To Be Opened
Direct mail campaigns live and die by open rates. The envelope is the first piece of creative. It determines whether the recipient opens the content or discards it. A campaign envelope with a compelling visual, a teaser message, or a distinctive brand color has significantly higher open rates. Plain white alternatives have lower open rates. We make direct mail campaign envelopes with the bold print quality and the creative flexibility that marketing teams need to produce mail that gets noticed. Campaign variants can be produced on the same envelope format with different outer messages for A/B testing and audience segmentation.
Legal, Financial, And Confidential Document Envelope Formats
Legal firms, financial institutions, healthcare providers, and educational organizations need mailing envelopes that communicate professionalism, formality, and discretion. A custom printed envelope with the organization’s logo, the department name, and a formal layout communicates authority and care for the recipient’s correspondence. Security-tinted inner lining is available for sensitive document envelopes. A formal window envelope format for statement and invoice mailings keeps address delivery automated while the branded outer communicates the sender identity clearly. We make all of these formats with the same print quality standard as our consumer brand envelopes.
Wholesale Envelope Supply For Offices And Mailing Operations
Offices, mailing houses, and direct mail operations with high volume envelope needs benefit from our wholesale pricing structure. The per-unit cost reduces progressively with volume so large mailing runs are genuinely cost-competitive against plain envelope alternatives. From 100 units per specification with free US shipping. No die plate charges. Free design support on every order. A free sample is available before production to confirm print quality and closure performance.
