How to Mail your 5x7 Postcards
💌 How to Mail Your 5x7 Delirious Aesthetics Postcard
Be advised that there is an upcoming price shift for stamps on July 13, 2025.
Sending a little love shouldn’t be confusing, but we get mailing a 5x7 postcard is a little different than those tiny touristy ones.
Here are tips to get your colored masterpieces safely to your bestie, grandma, or frenemy.
🖼 What Size Are These Again?
Our postcards are 5x7 inches, which means they fall under letter-size mail (not standard postcard size, which is 4x6).
Translation? You’ll need a First-Class Forever Stamp.
📮 TL;DR: What Stamp Do I Use?
| Mailing Type | Stamp Needed | Cost |
|---|---|---|
| Domestic (USA) | First-Class Forever 💌 | $0.73 |
| International 🌍 | Global Forever ✈️ | $1.65 |
| APO/FPO/DPO 📬 | First-Class Forever 💌 | $0.73 (Domestic Rate) |
✏️ Note: You cannot use a 56¢ postcard stamp unless your postcard is the tiny 4x6 type.
Perk: We only include First-Class Forever stamps, from a rotating selection, in our sets!
🧠 Why This Matters
We believe in coloring meant to be shared—and that includes actually mailing the joy.
No gatekeeping, no guessing, just real-world connection through tiny, beautiful art.

✉️ Envelope Needed?
Nope! Delirious Aesthetics postcards are made to mail as-is. Our bundled gift sets include envelopes just in case you’d like to protect your art!
