Case Study: Chingu scales global cohort communications 10x faster with Mailjet

How Chingu swapped hours of manual list juggling for automated Mailjet sends that keep its worldwide developer community focused and shipping

Chingu is a U.S.-based organization that helps developers gain real-world experience through remote six-week “Voyage” team projects. As its global cohorts grew, the team’s manual email process—copying addresses, sending individual messages, and managing reminders by hand—became a bottleneck. Chingu needed a more scalable way to handle onboarding, credentials, and project communications, so it turned to Mailjet’s Email API and templates.

Mailjet helped Chingu automate and streamline cohort communications with drag-and-drop templates, transactional email, SMTP Relay, contact management, and a lightweight REST API. The result was faster onboarding, more consistent messaging, and about 10,000 monthly emails delivered reliably with a “Good” deliverability rating. Mailjet also saved the team hours of manual work and helped keep participants engaged and projects on schedule.
