Club is an amazing tool if you plan to activate many influencers monthly or for specific campaigns.
Club has been a game-changer. It's our go-to platform for growing a loyal community that generates sales and brand awareness.

Since joining in June 2022, their ambassador community has generated over 21,000 social posts, capturing thousands of authentic reactions from real families and turning them into performance-ready assets.
By activating highly engaged customers, maintaining consistent mission cadence, and using structured communication through features like the Wall, Wonderbly built more than a content stream. They built infrastructure for peak performance.
This case study breaks down how Wonderbly transformed shareable product moments into a reliable growth channel, how they navigated migration without performance loss, and why community now plays a central role in their seasonal and organic marketing strategy.
“There’s this magic moment where the kid opens it and sees themselves…and it felt like we were missing out on capturing those real organic moments.”
Every order creates a moment people want to talk about: a child seeing their own name and story brought to life.
But like most brands, Wonderbly faced a familiar gap. The opportunity to engage with authentic, everyday customers sharing real reactions and real stories.
Wonderbly needed a way to:
● Consistently generate authentic, trusted content at scale
● Recruit and activate a community that genuinely loved the product
● Drive measurable revenue from a channel they could control
● Show up strongly around seasonal peaks like Black Friday and Christmas
The decision to build an ambassador community came from a simple observation: Wonderbly’s most human content always performed.
Real parents, real kids, real reactions.
“We recognised the value in organic content. People are really looking for that.”
The team also saw a strong fit between their audience and the kind of people who thrive in community-led programs: highly engaged customers who want to contribute, earn rewards, and be part of something.
“It aligned really well with our audience base.”
That consistency has compounded into meaningful commercial and content impact.
To date, Wonderbly’s community has driven over 21,000 social posts
That combination matters: revenue you can measure, plus a content library you can reuse.
Migration can be a risky moment for any brand. Communities can drop off. Performance can dip. Teams can lose momentum.
Wonderbly’s move from Brandbassador to Club held steady.
“The numbers were really positive. We expected quite a big dip… but it was pretty consistent.”
The confidence came down to two things:
● continuity with the same partner relationship and support model
● a community already engaged and familiar with how the program works
“It’s the same team working with us so there was that relationship already built up and the trust there.”
That split keeps the program moving quickly without bottlenecks.
“If it’s a small technical problem, we’ll use Support first… and the bigger questions go to the CSM.”
For Wonderbly, context and continuity also mattered, especially during team changes internally.
“When I first started working at Wonderbly and the community was already established… it felt like stepping into a brand new arena. Having people with that understanding is really useful.”
“Our CSM Beth was asking about Q1 goals and she already knew what I was going to say.”
This is what embedded Customer Success looks like in practice: less ramp time, fewer repeated explanations, more forward momentum
“We’ve been really happy with the consistency of newcomers… we’ve had really consistent growth of new followers and community members.”
A key driver of this performance has been Wonderbly’s commitment to keeping the community experience genuinely engaging.
“Our variety of missions and our consistency of posting really stands out.”
“We put in quite a lot of effort into making them more engaging and keeping the ambassadors happy.”
The team ran sales missions on the platform for the first time and saw immediate traction, without it feeling overly promotional.
“It was the first time we tried sales missions… and it completely took off, people were keen to get involved”
That readiness translated directly into performance during the highest-stakes retail period.
For Black Friday Wonderbly’s community generated 232 social posts alone
And across the wider Q4 period, Wonderbly significantly exceeded internal expectations.
“We had a really successful month.”
The takeaway is simple: when major moments hit, a well-run community is already warmed up and ready to act.
“You can definitely see the value of having that engaged user base for when those big occasion moments come.”
“I run organic social channels as well, and there’s a really nice crossover.”
They can seed campaigns with missions (often tied to new book releases or key occasions), then feed the resulting content back into their organic strategy with speed.
“Being able to run a freebie mission for a new book and get all that content back in time to share it is really fundamental.”
They also leverage community insights to inform what’s coming next.
“We get insights on upcoming books… it impacts a lot of different parts of our business.”
The Wall
Wonderbly uses the Wall as a weekly rhythm-setting tool: updates, recognition, and previews that keep the community motivated.
“A weekly wall post… we’ll shout out ambassadors, give a peek of what’s coming up, and get people engaged and excited.”
Why community works for Wonderbly:
“Organic content really performs for us.”
What the community drives across the business:
“We get insights, we get really nice content, they’re engaged in the sales missions… it impacts a lot of different parts of our business.”
How it feels as an engine:
“Having our community has been super valuable… from a number of different perspectives.”
Wonderbly’s success comes from turning emotional product moments into structured community activation through Club. By consistently engaging real families, maintaining a strong mission cadence, and using tools like the Wall to keep momentum high, they’ve built a system that captures authentic content at scale without losing the human element. The focus is clear: quality storytelling, seasonal readiness, and measurable participation.
The impact goes beyond social output. Through Club, the community fuels organic social strategy, supports new book launches, informs campaign planning, and strengthens peak trading periods like Black Friday and Christmas. What could have been one-off influencer bursts has become a reliable, always-on engine powered by genuine customer advocacy.
Since 2022, the pattern is consistent: steady member growth, strong participation, and performance when it matters most. Wonderbly didn’t just generate content on Club. They built a community engine that now underpins key moments across their marketing calendar.
