The problem it started from: drowning in admin
The pain points that shaped the design.
What the project works through
The moving parts of knowing and reaching your members
Custom Profiles
- Track what your group cares about
- For scouts: tie, rank, region
- Extra forms attach to any member
Email the Right People
- Filter by rank, region and more
- See the recipient count first
- No copy-pasted mailing lists
SMS In progress
- Text the same filtered groups
- For news that can't wait
- Uses the numbers already on file
Google Sheets Planned
- Bring in your existing lists
- Map columns to profile fields
- No retyping, no starting over
TryBooking Planned
- Pull in who booked what
- Match bookings to members
- Message attendees directly
Events & Camps
- Online registration and payment
- Family and day pricing
- Health and consent forms
How it fits together
Five steps, from your existing lists to the right inboxes.
Choose your fields
Bring in your data
Keep profiles current
Pick who to reach
Send email or SMS
Built for your members, not just a list
Why a spreadsheet plus a mail-out tool is the wrong shape for the problem
| Feature | Musterpost | Spreadsheet + mail-out |
|---|---|---|
| Member details | One profile per person | Copies in every file |
| Fields | Defined and validated | Whatever got typed |
| Send to one region or rank | ||
| Email and SMS from one place | ||
| Sheets and TryBooking data joined up | ||
| Access controls for youth data |
That mismatch was the reason to explore something purpose-built.

How it was designed to treat sensitive data
About this project
A demonstration, not a product for sale
Musterpost was built to explore how a group could know and reach its members — the interesting problems, not the business: profiles whose fields each group defines, data that validates itself, and messages that go to exactly the right people. Scouts are the first worked example; camps and events are one module within it.
It isn't a commercial service and isn't taking sign-ups — there's nothing to buy and nothing to launch. You're welcome to create an account and look around, but treat it as a sandbox: data is temporary and may be cleared at any time.

Have a look around the demo — no strings, nothing to buy.
