💌 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

Start your first sidequest

❤️ What sidequesters are saying

  • Hand holding a Sidequest Mail Club envelope with a red mission stamp before opening.

    Your First Letter

    You do something you probably would've postponed and you create a story where there would've been none.

  • People standing on a lake diving platform before jumping into the water

    A Few Months Later

    You start noticing opportunities for adventure hiding in ordinary life and the world feels a little less repetitive.

  • Hikers walking through a snowy mountain valley during an outdoor adventure

    Before You Realize It

    One sidequest turns into another and suddenly you're doing things that would've sounded unlike you just some time ago.

  • Three friends sharing a joyful moment outdoors during sunset

    One Year Later

    You have a collection of memories that wouldn't exist otherwise and a clear proof that life becomes more interesting when you participate in it.

  • Person crossing the Sahara Desert during a Marathon Des Sables 2026 endurance adventure

    Eventually

    You no longer wait for permission to make life interesting because you've become the type of person who actively seeks out and creates their own sidequests

This is what shows up at your mailbox:

🗺 A carefully chosen sidequest:
A simple real-world mission designed to spark curiosity, courage, or connection. No special skills, resources, or major time commitment required.

📬 A personal reflection letter:
A heartfelt letter from Aisha or Reio sharing a real story, lesson, or experience that inspired this month's sidequest.

📓 Reflection question:
A prompt for journalling or reflection designed to help you slow down and see your own life from a new perspective.

🎁 Something extra each month:
A small physical keepsake to remember the month (art prints, stickers, surprises, postcards and other treasures)

Each mail begins with a real story from our lives and turns it into a new story for yourself.

Join this month's sidequest
  • 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

Is Mail Club for me?

🤔 Is this for me?

You'll probably love Mail Club if...

• You keep saying, "We really should do that someday."
• Life has started feeling repetitive.
• You miss genuinely looking forward to something.
• You want more stories, fewer weekends that blur together.
• You're looking for a reason to actually do something instead of just scrolling.

🎲 How is this different from the decks?

The decks give you 50 sidequests to complete whenever inspiration strikes.

Mail Club is a slower, more intentional experience. Every month you receive one carefully crafted letter and one exclusive sidequest designed around a specific theme.

While the decks wait until you're ready, the Mail Club arrives before you are.

🤓 Is this some generic self-help challenges?

Absolutely not.

You won't find "wake up at 5am", "take a cold shower", or "clean your room" in here.

Every sidequest is created to help you collect experiences, not optimize your morning routine.

We're in the business of collecting stories, not productivity hacks

What can I expect?

✉️ What exactly will I receive?

Every month you'll receive a physical envelope containing:

  • A brand-new sidequest to complete
  • A personal founder's letter from Reio or Aisha
  • A reflection prompt
  • Extras like stickers, field notes, mini-posters or other collectible extras
  • The occasional surprise we don't want to spoil

Each month has its own theme, so no two envelopes are ever the same.

It's something to genuinely look forward to before another month quietly slips by.

🎒 What kinds of sidequests can I expect?

Every month is a surprise.

One month you might sign up for something you've always wanted to try.

Another month you might meet someone you'd never have spoken to otherwise.

Or create something. Or explore somewhere new. Or reconnect with a forgotten part of yourself.

Some sidequests take five minutes. Others may stay with you for years.

They're designed to gently push you outside your routine and towards designing a life that matches who you are at core.

⭐ Are all the sidequests "big adventures"?

Not at all.

Some sidequests take five minutes while others might stay with you for years.

They can happen at home or take you somewhere unexpected.

Our goal with the letters isn't to make your life harder, it's to gently stretch your comfort zone one month at a time.

Common worries

👤 Can I do them alone?

Absolutely. Many sidequests are designed for solo adventures, while others become even more memorable with friends, partner or family. There are no rules, meaning you decide how you complete each one.

😅 What if I'm an introvert?

Great!

Many of us are, including me (Reio)!

The sidequests aren't designed to turn you into someone you're not.

They're designed to help you become a little more of who you already are.

🫣 Am I gonna be publically embarrased doing the sidequests?

Not unless you want to 😁

None are designed to embarrass or humiliate you. You decide how far outside your comfort zone you want to step

Before you subscribe

📬 When will I get my first letter?

We ship letters on the 15th of every month from Estonia.

If you subscribe before the 15th, your first letter will be included in the next shipment.

Subscribe after the deadline and you'll automatically receive next month's adventure instead.

Typically the letter should arrive to your door within:
1-5 days in Northern EU & Baltics
1-3 weeks in Europe
1-4 weeks Internationally

The anticipation of not knowing when exactly your letter arrives is a huge part of the experience so take it in!

💳 Can I cancel anytime?

Yes. You can cancel, pause or even skip a month of your subscription anytime through your customer portal. There are no contracts or cancellation fees.

One last thing...

💌 Why physical letters?

Because screens are designed for us to consume and we wanted something that makes us pause.

We felt overwhelemed with the emails that we don't really care about and the notifications we ignore.

A letter arriving in your mailbox feels different. For a few minutes, nothing is competing for your attention. It's just you, the letter, and your mind thinking of the adventure that comes next.

📆 How long should I stay subscribed?

There isn't a right answer.

Every month passes whether we do something memorable with it or not.

The Mail Club exists to make sure another month doesn't quietly disappear into routine.

One month becomes one story.
Then another.
Then another.

And somewhere along the way something unexpected happens:
You stop waiting for life to happen to you.

You become the kind of person who naturally says yes more often, follows their curiosity, and creates their own adventures.

Stay for as long as the letters help you become that person.

Before Your First Letter Arrives

What is The Sidequest Mail Club?

The Sidequest Mail Club is a monthly letter for people who don't want life to become the same month repeated over and over again.

Every month, you'll receive a real story from our lives, a sidequest inspired by that story, and a reminder that life is happening right now.

The goal isn't to give you more things to own.

The goal is to help you collect more stories you'll actually remember.

When will I get my mail?

Sidequest Mail leaves our HQ every month on the 15th. From there, the arrival of your letter can vary quite a lot:

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

The anticipation of not knowing when exactly your letter arrives is a huge part of the experience so take it in!

What countries do you ship to?

Sidequest Letters ship internationally 🌍

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 fresh sidequest inspired by the letter (something real to go and do)
  • ✉️ A personal reflection letter from one of our founders (Aisha or Reio, hi!)
  • 📓 A reflection question to help you see a new perspective
  • 🎁 Extras like stickers, posters, or surprise inserts

Each one is designed to give you something to look forward to and make sure the month doesn't pass by without a story worth telling.

What kind of sidequests are these?

Our sidequests aren't productivity hacks, chores, or self-improvement homework.

They're open-ended invitations designed to spark curiosity, courage, connection, or adventure.

The same sidequest can lead two people in completely different directions.

For example, one person's sidequest might become an improv class. Someone else's might become salsa lessons, a marathon, or applying for a dream job.

We provide the spark. What happens next becomes uniquely yours.

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 once you login with the same e-mail you used when purchasing.

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's the difference between the decks and Mail Club?

The decks are about adventure.

Mail Club is about transformation.

The decks give you 50 sidequests to help you break out of routine, try new things, and create stories worth telling.

Mail Club takes a more focused approach.

Each month explores a single theme through a personal letter, reflection prompts, and an exclusive sidequest designed to help you experience that idea in the real world.

The decks give you dozens of different adventures. Mail Club invites you to go deeper into one each month.

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.

If a letter gets lost or doesn’t arrive, just contact us at orders@onemoresidequest.com and we’ll resend it or sort it out properly.

I loved the concept. The story really catched my interest and I love to do the side quest of this month. I was happy when I saw finally good news in the mail and the side quest of this month really take you out of your comfort zone but at the same time aim you to make something for yourself. I’m 100% in.

I got my first Sidequest newsletter today. At first I wasn't sure what I was going to do but now I think I have an idea, watch this space..... Just a suggestion, but it might be nice to have a community page so we can all see what everyone's up to.

K
Karolina

A great little thing to give you that final push and help you move from the “I want to” phase to the “just do it” phase :)
And simply to get some positive emotions from the letter itself

The letter is very exciting and the experience of reading it is really cool. The only thing I wish it could be better is that it takes too long to arrive in certain countries (Like mine, in Brazil).

I recieved my first letter, it is really great, i will learn about the art of Monet. I already purchased a book and i will make my own Monet painting with pastels. In your letter you mentioned the previous letters and i started missing the information on thoose. It would be nice if we could receive tje preciousones somehow. Thank you very much, it makes me happier just to wait for something every month.

I received Aish's July letter and absolutely loved it! The personal touch, the camping story, and the adventure spirit really came through. It arrived right when I needed a little escape. Highly recommend the Sidequest Mail Club to anyone looking for a bit more magic in their mailbox.

Super basic (one sentence) “quest”, not worth spending money

Hey! Sorry this one didn’t land for you. Each Sidequest Mail Club letter includes one simple challenge designed to get you out into the real world, alongside a personal letter and other little surprises. The magic happens when you actually do the sidequest, not just read it. We know it won’t be everyone’s thing, but we appreciate you giving it a try! 🧡

Amazing! Exactly what I needed right here, right now!

The first thing I loved was that I was genuinely surprised to find the letter in my mailbox - because I had forgotten I ordered it about a month ago. Isn’t that the best feeling, being surprised by mysterious mail? 😍 I loved the beautiful story and picture, that the letter contained multiple physical things (really like a little surprise package), and I am already planning my sidequest - it fits me exactly and I’m looking forward a lot :) I am planning to gift my best friend a few letters without telling him so he’ll get a nice surprise as well!

It made me do the things that I was afraid of doing. Just that little push in the back I needed with the beautiful written letter. Thank you for helping me become the more adventurous person I wanted to become

This is SUCH a lovely idea! In a world of a thousand emails a day it's so special to just receive a real letter again. It's beautifully done, with special paper and font and little cards and stickers. I love the idea that I never know what I'll get and to take the time to read through everything (WITHOUT a screen). I've received one letter so far and I'm looking forward to more. I really recommend trying this mail club, especially if you feel sort of lost and disconnected like me.

EMILY!! You made my day thank you so much!! 😭 -Reio
