Weekend Wonders: The Truth About USPS Sunday Deliveries and How to Mail a Letter the Right Way
In today’s fast-paced world, getting your mail and packages delivered quickly and efficiently is more important than ever. Whether you’re sending out invitations, legal documents, or ecommerce packages, knowing how to use the postal system effectively can save you time and hassle. Two of the most common questions people have are: how to mail a letter correctly and does USPS deliver on Sunday?
Understanding the intricacies of the United States Postal Service (USPS) will help you navigate your mailing needs without unnecessary delays or surprises. This article will guide you through both of these topics in detail, helping you feel confident the next time you reach for an envelope or track a package.
Why USPS Is Still Relevant in a Digital World
Despite the rise of email, instant messaging, and digital signatures, USPS remains a crucial component of communication and logistics. Millions of Americans rely on USPS every day to handle both personal and business correspondence. Whether you’re sending a birthday card across the country or shipping a product to a customer, USPS offers reliable, affordable options for just about everyone.
Their reach spans every corner of the country, including rural and remote locations where other private carriers might not operate. Plus, with multiple delivery options including Priority Mail, First-Class Mail, and Certified Mail, there’s flexibility for all kinds of needs and budgets.
How to Mail a Letter: A Step-by-Step Guide
If it’s been a while since you’ve sent a physical letter—or if you’ve never done it before—you might be surprised by how easy it is. Here’s a quick rundown of how to mail a letter properly:
1. Choose the Right Envelope
Make sure your envelope fits your contents snugly. For standard letters, a #10 envelope (4 1/8″ x 9 1/2″) works well. If you’re mailing photos or documents that shouldn’t be folded, consider a larger envelope or rigid mailer.
2. Write the Addresses Clearly
Use dark ink and legible handwriting or print the addresses clearly. The sender’s (your) address goes in the top left corner, and the recipient’s address should be centered in the middle of the envelope. Include full names, street addresses, cities, states, and ZIP codes.
3. Affix Proper Postage
As of 2025, a standard First-Class Mail stamp costs $0.68. Make sure your envelope weighs less than 1 ounce, or you’ll need additional postage. If in doubt, ask your local post office to weigh it.
4. Drop It Off
You can place your stamped letter in a blue USPS mailbox, hand it to a postal worker, or drop it off at your local post office. If you want tracking or faster delivery, consider sending it via Priority Mail or Certified Mail.

Tips to Ensure Your Mail Gets Delivered Smoothly
Even though mailing a letter is simple, a few tips can improve your success rate and help avoid delays:
- Double-check addresses before sealing the envelope. Even a small typo can result in a lost letter.
- Use the correct postage. Underpaying can result in returned mail or delays.
- Consider tracking options for important mail. Services like Certified Mail or Priority Mail provide peace of mind.
- Avoid mailing sensitive items without proper insurance or protection. For example, don’t send cash or original documents without a secure method.
Mailing in the Modern Age
It may seem old-fashioned to send a letter in today’s digital age, but physical mail still plays a key role in communication. From legal paperwork to personal notes, physical letters convey a sense of authenticity and care that a text message or email just can’t match.
Whether you’re writing a thank-you card, applying for a job, or running a business, mastering the basics of USPS services can go a long way in helping you stay organized and efficient.
Final Thoughts
