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

Start your first sidequest
  • 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 the next 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

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 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 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.

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.

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