About Josephine

Do you have traffic... but not enough conversions?
Do you send emails... but they don't convert?
Is your CRM set up... but not really optimized?

My name is Joséphine and I help e-commerce brands turn their emails into a loyalty & conversion driver through:
  • High-performing campaigns on Klaviyo and Brevo,
  • Automated and optimized email flows,

This hands-on experience allows me to get straight to the point and implement only what generates sales, without any fluff.
