A Private Pen Pal Network for Your Organisation
Stamplo Organisations lets schools, companies, clubs, and community groups create a closed network where children can only discover and connect with others inside your group.
Every safety protection stays in place. Parents or legal guardians manage everything. You simply share an invite link.

Designed for Schools, Companies & Community Groups
Schools
Create a private network for your school community. Children discover pen pals only from families who have joined your school's Stamplo network.
Companies
Offer a meaningful family benefit to your employees. Children of colleagues across different offices and countries can connect safely.
Home Ed Groups
Co-ops and home education communities can create a shared space where children connect with others from within their trusted group.
Community Groups
Clubs, charities, faith groups, and community organisations can invite families to build connections within their community.
How It Works
We Set Up Your Network
Get in touch and we'll create your organisation's private Stamplo network and generate a unique invite link for your families.
Families Join via Invite
Share the invite link in your newsletter, intranet, or communications. Parents or legal guardians register, verify their identity, and add their child.
Children Connect Safely
Children in your network discover only other children from your group. All parental approval, encryption, and safety protections remain fully in place.
What Your Organisation Actually Does
- ✔ Share the invite link with your families
- ✔ Mention Stamplo in a newsletter or email
- ✔ That's it
Stamplo handles accounts, identity verification, safety checks, moderation, and infrastructure. Your organisation has no ongoing responsibilities.
Example Uses
A primary school creates a Stamplo network for Years 4–6 as part of a pen pal or cultural exchange project.
A global company connects employees' children across offices in different countries as a family wellbeing benefit.
A home education co-op creates a private pen pal network for its members — no strangers, no global discovery.
A youth group builds connections between children in different regions within a trusted, closed network.
Every Safety Protection Stays In Place
Organisations simply limit discovery to children within the same group — every safety protection remains exactly the same.
Every parent or legal guardian must complete real-time identity verification before their child can participate.
Every pen pal connection requires approval from both sets of parents or legal guardians.
Every letter is reviewed and approved by both parents before delivery — the Four-Eyes Check.
All letters and images are encrypted at rest and in transit.
Your organisation has no access to children's letters, images, or private communications.
Children can flag any letter that worries them — parents are notified immediately.
Stamplo Limited is ICO registered (ZB927463) and aligned with the ICO Children's Code.
No ads, no tracking, no algorithms. Ever.
For Designated Safeguarding Leads (DSLs)
No teacher accounts, no school logins, no school data collected. Parents or legal guardians manage all activity independently. Schools have no ongoing safeguarding responsibilities on the platform.
