Case Study: Linxo doubles its user base and secures email notifications with Mailjet

Linxo, Building a Secure and Private Email-Centered Product, Doubles Their User Base in One Year

Linxo is a French fintech app that aggregates users’ financial accounts and relies heavily on email notifications. Because customers share sensitive banking data and French/EU privacy rules are strict, Linxo needed a secure, scalable email solution that protected user data, ensured deliverability, and met local regulations as the company grew rapidly.

Linxo partnered with Mailjet to host EU-based data, encrypt API communications, implement authentication (SPF/DKIM/DMARC) and use a dedicated IP for sender reputation, plus ongoing deliverability support. The result: reliable, secure email delivery that scaled with the business—Linxo doubled its user base in one year while increasing email volume without compromising security or inbox placement.
