Add your logo and return address
Add your logo and return address for a more professional, recognizable business envelope.
Best choice:
- If you're mailing letters and notices
- If sending branded customer correspondence
- For general business mail that doesn’t need a window
2
Choose window options
Show the recipient address through the envelope window to reduce manual addressing and speed up mailing.
Best choice:
- For mailing invoices or statements

- For any mail where the address is printed on the document inside
3
Add self-seal features
Use peel-and-seal closures to make mailing faster and easier when you’re preparing large quantities.
Best choice:

- For sending batches of letters, notices, or forms

4
Add security tint for privacy

- For mailing checks or financial statements
- For sending confidential HR or legal documents

Stick with the #10 Standard Size
The industry standard for a reason. It perfectly fits 8.5" x 11" paper folded into thirds and fits most mailing equipment.
Best choice:
- For standard business letters and invoices
- If you want the most "versatile" envelope in the office
- When you aren't sure which size to pick—this is the safe bet

If you need "full bleed" printing that reaches every edge or a unique size that doesn't exist in stock, we build it from scratch.
Best choice:
- For high-impact branding and full-color patterns
- For unique sizes tailored to specific marketing kits
- When standard "off-the-shelf" envelopes won't cut it
Custom business envelopes help you send mail in a way that fits your business. You can add your logo and return address, choose the right size for the documents you send, and select features that make your mail look more professional, stay more secure, and move through your workflow more easily.
Choose the Right Size for Your Business Envelopes.
For most businesses, the #10 Envelope is the go-to choice. It’s the safe, professional standard designed to fit 8.5" x 11" paper folded perfectly into thirds.
However, businesses often need different sizes for specific mailing tasks—whether it's ensuring a reply envelope fits inside a mailer, sending out thick marketing booklets, or mailing contracts that cannot be folded.

Frequently Asked Questions
What makes a business envelope custom?
A custom business envelope is any envelope tailored to fit the way your business sends mail. That can include printed branding, the right size for your documents, useful features like windows or security tint, or a fully customized format built around a specific mailing need.
How do I know if a standard envelope will work?
A standard envelope usually works if you are mailing common business documents like letters, invoices, or statements and only need to add branding, choose the right size, or select a feature such as self-seal or security tint. If your mailing requires a specific layout, window placement, or special format, a more customized option may be a better fit.
Which envelope features do businesses use most often?
Many businesses choose features based on how they mail. Window envelopes work well for invoices and statements, security tint helps protect private information, and self-seal closures make everyday mailing faster and easier.
When should I choose a fully customized envelope?
A fully customized envelope makes sense when standard options do not quite match your needs. For example, you may need a specific window placement, a certain seal type, extra privacy, or a custom printed design that supports a unique document or workflow.
