From full moon to mailbox: how a Luna Post postcard gets made

We'd like you to know exactly what you're holding, so here's the whole process, from a full moon showing up on the calendar to a postcard arriving in your mailbox.

1. The date comes from astronomy, not from billing

Every edition is tied to a real full moon. We take the dates from astronomical data, which is why editions don't land on the same day each month and why they're about twenty-nine and a half days apart instead of an even thirty. It also means your card follows the moon, not the day you signed up.

2. The art is made for that particular moon

The front of each postcard is original art for that edition. The Buck Moon has antlers, and the Cold Moon has a long winter night. We want it to be worth keeping on its own, because a card you pin up keeps reminding you long after the month ends. It's printed edge to edge on a 4×6 card, and the picture you see on the website is a smaller copy of the print file.

3. Your birthday becomes numbers and signs, and a card is drawn

From the details you gave us when you signed up, we work out your star sign, your Chinese zodiac animal and element, and several numerology numbers, including your Life Path, your Birth Day and the numbers that come from your name. Then a tarot card is drawn for you for that month, and your note is written with that card's meaning at its heart.

Two people born in the same week won't get the same postcard. Between the card, the numerology and the numbers that change for each person every month, the combinations are far more varied than a horoscope written for twelve signs.

4. A person reads it before it prints

The first draft of each note is written with help from AI. We want to tell you that plainly, since there's a lot of astrology writing out there made in bulk, and you shouldn't have to guess which kind you're holding.

The difference is what happens next. A person reads every fortune and approves it before it goes to print, checking it against a written standard: easy to understand, warm, clear about what the card means, one small thing you can do, and no filler. If a note doesn't meet that standard, it gets rewritten before it's approved.

5. Printing and mail

Approved cards are turned into print-ready files and sent to our print and mail partner, Lob, who prints them and hands them to the postal service. Lob receives only the name and address needed to deliver your card. Delivery usually takes about ten business days after mailing, which is why editions go out well before the full moon. We want the card in your hands around the moon itself, rather than just leaving the printer that day.

6. What we don't do

We don't sell or share your information, we don't use ad trackers, and we only use your birthday to write your card. You can read all of that in our privacy policy, which we kept short on purpose.

Why show you the seams

Luna Post is meant to be a practice you can trust. Knowing that a real full moon sets the date, that every person's card is drawn separately, and that a person reads the writing before it prints doesn't take away from the moment it arrives. It's the same idea as not a prediction, a mirror. The value comes from what you do with the card, and that's easier when you know how it was made.
