Musterpost was built by a scout leader with over 20 years' experience designing and building large, database-driven systems.
After years of running a group held together with spreadsheets and lost emails, one idea kept coming back: every club tracks different things about its people, and needs to reach the right ones. Scouts track a tie, a rank, a region. A sports club tracks a team and a grade. The shape changes. The problem doesn't.
Somewhere along the way, administration took over the volunteering. What used to be a few paper forms became endless spreadsheets. Shared Google Docs. Email threads stretching back years. WhatsApp groups where important information disappeared under memes.
Leaders weren't running their groups anymore. They were drowning in data—and still didn't have the information they actually needed.
The problems we kept hitting
Every term. Every event. The same headaches.
Generic tools don't know what matters to you
A mailing list knows a name and an email. That's it. For scouts we also need a tie colour, a rank, a region. Every club has its own version of that, and most tools have nowhere to put it.
The same details, asked for again and again
Every event, every term, families filled in the same forms. Contact details, medical notes, consent. Half the time we already had it, somewhere.
Messaging the right people was hard
We wanted to email just the leaders in one region, or just one age section. Instead it was copy-pasting addresses out of a spreadsheet and hoping nobody got missed.
Data scattered everywhere
One family's details were in a Google Sheet. Another's were in a booking system. Allergies were in an email thread from years ago. Nothing lined up.
Forms that couldn't change
Every time we needed to ask something new, it meant a new spreadsheet column or a new paper form. There was no easy way to say 'this group needs to answer these questions'.
No one knew who was actually in the group
People would age out or move away, but they'd stay on our lists forever. New leaders had no idea who was current and who was history.
So we started building something
Musterpost is a design project. You set up the profile your group needs—for us that's name, tie, rank and region—then collect details with forms you design yourself, and email the people who match. Just the Cubs. Just one region.
Scouts is the first use case, not the whole idea. It's built by someone who designs data systems for a living—and who also happens to understand scouting from the inside.
Some of it works today: custom profiles, forms, and email to filtered groups. There's also an events & camps module with online bookings. Other parts are still on the way—SMS, and pulling data in from Google Sheets and TryBooking are planned, not built. It's a demonstration, not a commercial product.
What we believe
Admin should be invisible
The best admin tool is the one you barely notice. It just works, so you can focus on your people.
Data belongs to you
Your member information is yours. We're just holding it safely until you need it.
Simple beats powerful
We'd rather do 10 things brilliantly than 100 things badly. No feature bloat.
Built for volunteers
Club leaders aren't IT professionals. The software should work for real people with limited time.
Your group, your fields
Every club tracks different things. You should be able to add what you need without asking a developer.
Security isn't optional
Member data, and especially children's data, deserves careful handling.
Started with scouts, built for any group
It's a design project, still being worked on. You're welcome to look around—just treat it as a sandbox, as data may be cleared at any time.
