In our latest Easypromos case study for book marketing, we look at how Boolino added almost 12,000 users to their database and increased their reach online. The subscription service for young readers harnessed the power of word-of-mouth marketing to create a phenomenally successful book marketing campaign.

The company

Boolino logo

Boolino is a book recommendation service for children and young readers, with more than 225,000 registered users in Spain. With the acquisition of a similar service that had roots in the UK school sector, Boolino has become the biggest private initiative platform for encouraging young bookworms. Their slogan is Creating readers.

The challenge

Boolino wanted to capture a database of potential clients. But their goal was more complex than simply collecting a list of names. They also wanted to segment their sales leads:

  • by reading language
  • by reading age

This information would be valuable market research for Boolino – and help them to target promotions and offers on an individual level.

The campaign

In order to reach as many high-quality leads as possible, Boolino settled on a recruitment contest.

The idea was simple: every participant who recruited 5 friends would win a free book. And whenever someone signed up, they added their details to the Boolino database – including contact details, reading age and language.

But Boolino used all the features available to maximize the impact of their campaign. Every time a participant successfully recruited someone, they received an automated email from the Easypromos platform to update them on their progress.

The email also included tips and suggested channels for adding more recruits, such as parenting groups on Whatsapp, Facebook posts, and so on. Every single participant was assigned a unique recruiting URL that no one else could use.

Over time, Boolino experimented with different prizes. Their initial target audience was 4-6-year-olds who read in Catalan, so the prize was a Catalan book. Just a few months later, Boolino repeated the campaign with a Spanish book, in order to reach a wider audience of Spanish readers.R

The result

  • 11,800 participants added to the Boolino database
  • Increase in followers and engagement on the social networks where Boolino shared the contest
  • Increase in brand awareness through social media posts and the recruitment campaign
