Envelopes - Common Questions
What are envelopes and mailers used for?
Envelopes and mailers are used to send letters, documents, or small items securely through the mail. They help protect the contents and ensure they reach their destination safely.
How do I know what size envelope I need?
Envelopes are categorized by a standard number system (like #10 for business letters) and their dimensions in inches. A good rule of thumb is to choose an envelope that is at least ¼ inch wider and ½ inch longer than the contents you're mailing. Most online stores have size charts to help you visualize what fits.
What does "self-seal" mean?
Self-seal envelopes have a strip of strong, pressure-sensitive adhesive protected by a removable liner. To seal it, you just peel off the liner and press the flap down (no licking or moisture is required). This is a popular, clean, and convenient option for both office and home use.
How should I address an envelope correctly?
Write the recipient's address in the center of the envelope clearly, including name, street address, city, state, ZIP code, and country if international. Don't forget to add your return address in the top left corner.
