Because behind every mailbox is a tiny army of magic-makers in utilitarian navy shorts (it's a vibe)
The U.S. Postal Service has been delivering love letters, birthday cards, and random coupons for centuries—but there’s way more to it than stamps and sorting machines.
Whether you’re new to snail mail or just a fan of dropping notes in the blue box, here are a few things you probably didn’t know about the USPS… and why it's still one of the coolest things we use every day.
1. You Can Put Mail in Your Own Mailbox (Flag Up = Let’s Go 🚩)
Yes, you don’t even need to leave your house.
Pop your stamped letter in your own mailbox and flip that little red flag up—your mail carrier will grab it when they drop off your mail.
Things you can mail from home:
-
Cards
-
Letters
-
Small packages (with a label + postage)
2. Forever Stamps Work… Forever
Bought a stamp in 2001 and just found it in a junk drawer? Good news: it still works.
Forever Stamps always cover the cost of a 1 oz First-Class letter, no matter how many price increases happen. So yes, that flag stamp from 10 years ago is still gold.
3. There Are Stamps for Everything
From sharks and sci-fi to snowflakes and Pixar characters, USPS has some of the coolest stamp designs, and you bet I always ask the options when I take a trip to the post office!
The variation in designs is perfect for:
-
Matching your card’s vibe
-
Adding a little extra joy to the envelope
-
Making your message feel even more personal
Bonus: They sell stamps online, and shipping is quick. usps.com
4. USPS Has Its Own Free Scheduling Tool
Sending a package and don’t want to leave the house?
You can schedule a free pickup on the USPS website. Your carrier will come grab your outgoing mail while doing their usual route.
File under: things you didn’t know you needed.
5. Mail Can Travel by Plane, Truck, Boat… Even Mules
Yep, in remote parts of Arizona, USPS still delivers mail by mule train down into the Grand Canyon.
They’ll literally do whatever it takes to get a card into someone’s hands.
Rain, snow, sleet, and steep canyon trails included. Talk about commitment to the craft.
6. You Can Track Your Mailbox
With Informed Delivery, USPS emails you a preview of what’s coming to your mailbox that day—including scans of letters and cards. It’s weirdly exciting and completely free to sign up for.
Great for:
-
Knowing when a special card is about to land
-
Prepping for unexpected bills
-
Building anticipation for your own happy mail
7. It’s Still One of the Best Deals Around
For under $1, you can send a card across the country that makes someone cry (in a good way).
No app required. No data plan needed.
Just ink, paper, and a little sticker in the corner.
In a world of unread texts and forgotten DMs, a handwritten card is basically emotional gold.
