How to Send a Letter in inZOI
Sending a letter is super simple. First step? Find a mailbox.
Take your Zoi outside and wander around your city. You’ll spot different mailboxes depending on where you live:
- Red mailboxes in Dowon
- Blue mailboxes in Bliss Bay City
So keep an eye out for those pops of color. Once you find one, you’re good to go.
Can’t Find a Mailbox?
No worries! You can just buy your own.
- Open Build Mode
- Search for “Mailbox”
- You’ll see both red and blue options
- Pick your favorite, buy it, and place it wherever you want in your city
Each mailbox only costs around 150 Meow Coins, so it’s super affordable. If you’re running low on funds, don’t forget there’s always the money cheat to give your wallet a little boost.

Sending the Letter
Once you’ve found or placed a mailbox, walk up to it and click on it. You’ll see a few different options:
- Send Letter
- Send Postcard
- Donate Anonymously
- Donate to the Local Community
To send a letter, just pick the Send Letter option. It only costs 1 Meow Coin, so basically anyone can do it.
Urge: Send a Congratulatory Letter
Sometimes, your Zoi might even get the urge to send a congratulations letter. When that happens, a special option will appear:
“Send Congratulatory Letter to Acquaintance”
Completing this Urge will reward you with a few Meow Coins—plus, it’s a nice way to build relationships with other Zois.
So whether you’re keeping in touch, spreading some good vibes, or knocking out a Urge, sending letters in inZOI is an easy and rewarding little moment. Grab a mailbox, drop that letter, and let your Zoi share some love the old-fashioned way.
