Preparing Sidequest Mail Club letters for monthly delivery

💌 Your monthly invitation to feel more alive

You probably don't need more inspiration. You already have enough saved posts, bookmarked videos and ideas you'll get to "one day."

But here's how it usually goes:
Life gets overwhelming.
The things you wanted to try gets pushed to next week.
Then next month.
Then someday...

The Sidequest Mail Club exists to shrink the gap between "one day" and today.

Every month, a letter arrives with a real story, a sidequest, and one reminder:
Life is happening right now.

The gap between "one day" and today is smaller than you think. It's about the size of a letter

It’s bigger than the letter

The letter is just an excuse. The real thing you're collecting is the stories of things you actually did, the type of stories you'd wanna tell all your friends, that make a month memorable instead of having it just pass by again.

Over time, every sidequest you go on and the stories you collect become something bigger:

A life that finally starts looking like the one you always had in your mind.


The letter just happens to be how it starts

Stack of Sidequest Mail Club envelopes ready to deliver monthly adventures

This is what shows up at your mailbox:

  • A carefully chosen sidequest for your month
  • The real story that inspired it (from Aisha or Reio, hi!)
  • Themed original handrawn prints & art for each letter
  • Something extra each month to remember the month

Each one starts with a real story, something that happened in our lives, and turns it into a sidequest you go out and do yourself

  • You keep saying “one day”

    You have a list of things you want to do eventually. But somehow months keep disappearing.

    Maybe you just need something that nudges one of them into reality

  • You save ideas instead of acting on them

    Your social media & camera roll is full of ideas.


    This gives you permission to explore all of these ideas.

  • You want something to look forward to

    Most things arriving at your door ask you to consume more or.. to pay your bills.

    This gives you one thing each month you're genuinely excited to open

  • You want more stories in your life

    You care less about impressive achievements and more about the moments that make you think "I'm glad I did that."

    This might become your monthly excuse to collect one more

💌 Letters go out 15th every month

There’s something weirdly magical about knowing other people are opening the exact same letter at the same time as you

Before Your First Letter Arrives

What is The Sidequest Mail Club?

The Sidequest Mail Club is a monthly ritual, a physical letter that shows up at your (or someone else’s) door with a new story and sidequest to step into.

But it’s not just a letter.

Each one starts with a real story, something that actually happened, and turns it into a sidequest you go out and do yourself.

At the same time, people all over the world are opening the exact same letter. Reading the same story. Turning it into their own version of it.

Inside, you’ll find the letter, your sidequest, and occasional extras that make it feel like something worth keeping, not just reading.

It’s designed to interrupt your routine and give you something more meaningful to do than scrolling.

When will I get my mail?

Sidequest Mail leave our HQ every month on the 15th

Europe: usually 2–14 business days
International: usually 1–4 weeks

Every letter is packed by us in Estonia 🇪🇪

What countries do you ship to?

Sidequest Letters ship internationally 🌍 Yes, even to the US, Canada & Australia!

There are only a few countries we don’t currently ship to because we want to make sure your letter actually makes it safely to your mailbox.

If your country isn’t available at checkout, send us a message at hello@onemoresidequest.com and we’ll see what we can do.

What exactly will I receive?

Every letter includes:

  • ✉️ A beautifully designed physical letter from one of our founders (Aisha or Reio, hi!)
  • 🎲 A fresh sidequest inspired by the story (something real to go and do)
  • 🎁 Extras like stickers, posters, or surprise inserts

Some months are simple. Some months have more going on, but every time, it’s something that feels intentional like it was made to be opened, not thrown away.

Can I cancel or pause?

Yes, anytime.

If you’ve chosen a subscription, you can cancel or pause it whenever you want from your subscription management page.

What if I need to change the address?

No problem.

You can update the delivery address before the next shipment goes out from your subscription management page

What if I didn't get my letter?

If something goes wrong, we’ll fix it.

Shipping isn’t perfect, but we take responsibility for making sure the experience is.
