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

Here's the whole pipeline, honestly, from the moment a moon appears on the calendar to the moment a card lands on your kitchen counter.

1. The date comes from astronomy, not from billing

Every edition is anchored to a real full moon. The dates are pulled from astronomical data, not chosen for convenience, which is why editions don't land on the same day each month and why the gap between them is about 29 and a half days rather than a tidy 30. It also means your card isn't tied to the day you happened to subscribe.

2. The art is made for that specific moon

The front of each postcard is original artwork for that edition — the Buck Moon gets antlers, the Cold Moon gets the long night. It's designed as something worth keeping on its own, without the writing, because a card you'd pin up is a card that keeps working after the month ends. The print file is a full-bleed 4×6 at print resolution; what the website shows you is a downscaled copy.

3. The fortune is written from your birthday, and a card is drawn

Your Western star sign, your Chinese zodiac animal and its element, and several numerology numbers — Life Path, Birth Day, and the name-derived ones — are computed from what you gave us at signup. Then a tarot card is drawn for you for that month, upright or reversed, and the reflection is written with that card's meaning as its subject.

Two subscribers born in the same week will not get the same postcard. Between the card draw, the numerology, and the monthly numbers that change for each person, the combinations don't collide the way a twelve-sign horoscope does.

4. A person reads it before it prints

The drafting is done with AI assistance. We'd rather say that plainly than have you assume otherwise, because the internet is full of astrology content generated at volume and nobody should have to guess which kind they're holding. What's different here is the gate at the end: every fortune is reviewed and approved by a human before it goes to print, against a written standard — concrete, one clear action, no jargon, no filler, no fortune that could have been about anyone. Anything that doesn't pass gets rewritten or redrawn.

5. Printing and mail

Approved cards are rendered to print-ready files and handed to a print-and-mail partner (Lob), who prints them and puts them into the postal system. Our print partner receives only the name and address needed to deliver the card. Delivery typically runs about ten business days from the mailing run, which is why editions go out well before the full moon rather than on the night of it: the goal is a card in your hands around the moon, not a card entering a warehouse that day.

6. What we don't do

We don't sell or share subscriber information, we don't run ad trackers, and we don't do anything with your birthday except write your card with it. That's in plain language in the privacy policy, which is short on purpose.

Why show the seams

Because the product is a practice, not a trick. Knowing that a real full moon sets the date, that the tarot draw is genuinely random per person, and that a human reads the writing before it prints doesn't diminish the card when it arrives. It's the same argument as not a prediction, a mirror: what makes it worth opening is what you do with it, and that works better when you know exactly what you're holding.
