Case Study: Causes achieves 20% increase in clicks with Mailgun

Causes Sees 20% Increase In Clicks With Mailgun

Causes, a San Francisco–based platform recently acquired by Brigade with 186 million registered users, relied on email as its primary communication channel. Managing more than 30 million sends per month on complex in‑house PowerMTA clusters led to deliverability issues, heavy DevOps overhead, and slow change cycles, so Causes ran a two‑month RFP and chose Mailgun.

Mailgun delivered a managed email service with a customized delivery plan, advanced segmentation strategy, proactive reputation management, and 24/7 integration support—simplifying domain rollouts and reducing engineering workload. The change improved deliverability and engagement, driving a 20% increase in clicks and sender scores that rarely fell below 80 and typically stayed above 90.
