Case Study: Macmillan Cancer Support achieves near-elimination of spam and reliable email performance with Mimecast Email Security

Mimecast Email Security Banishes Spam for Macmillan Cancer Support

Macmillan Cancer Support, a UK charity with about 1,300 email users, was struggling with a growing spam problem that flooded its servers, slowed system performance and created a heavy administration burden—including frequent false positives—that threatened the productivity of its largely mobile fundraising team and required a cost‑effective solution with clear ROI.

After a rigorous selection process Macmillan adopted Mimecast’s cloud-based Email Security (backed by robust anti-virus/anti-spam SLAs). Mimecast’s cloud inspection stopped the spam before it hit Macmillan’s systems, dramatically reduced false positives and support calls (to roughly six a year), protected core email performance, delivered a seamless migration and proactive support, and freed IT to focus on higher‑value activities.
