Case Study: Webmecanik achieves 2M emails per month and 99% delivery rate with Mailjet

Webmecanik trusts Mailjet to send millions of emails every month on behalf of its clients

Webmecanik is an open‑source SaaS marketing automation provider used by 300+ clients across Europe and Canada (including Darty, Renault Sport and T‑Systems). Sending about 2 million emails per month, the company needed a reliable, responsive European partner to ensure high deliverability, strong routing, and strict data protection in line with GDPR requirements.

Webmecanik integrated Mailjet via a Mautic plugin (using SMTP relays) so clients can automate sending with automated DNS/API key setup and European data hosting. With Mailjet’s dedicated support and compliance readiness, Webmecanik has deployed 400 API keys and achieved ~99% delivery and up to 80% open rates, while simplifying management and GDPR preparation.
