Case Study: Happn achieves scalable, multilingual email deliverability and seamless developer-marketing collaboration with Mailjet

Happn Partners With Mailjet For Seamless Collaboration Between Developer And Marketing Teams

Happn, a 100% mobile, geo‑localized dating app launched in 2014, grew quickly to 26 million users across about 30 countries and communicates in more than 15 languages. Its small CRM team needed a flexible, GDPR‑compliant email solution that ensured strong deliverability and consistent design for high‑priority transactional messages (especially onboarding) and localized marketing newsletters as the company expanded into new markets.

Happn chose Mailjet for its deliverability, compliance, easy drag‑and‑drop design tools and dedicated customer success support. Mailjet helped implement a scalable mailing structure for transactional onboarding emails, multilingual newsletters and partner campaigns, enabling coherent branding across languages, improved deliverability, faster execution by the CRM team and reliable support as Happn scaled into new regions.
