Case Study: Puresend reduces servers by two-thirds and improves deliverability with Message Systems

Puresend Pushes the Envelope with Message Systems

Puresend is a web-based email service provider that delivers campaigns for some of the world’s largest marketers and can send over one billion messages per month. As spam, phishing and ISP countermeasures escalated, Puresend’s original appliance-based delivery platform struggled to scale, control delivery behavior and provide reliable failover, making it harder and more expensive to get legitimate mail into customer inboxes.

In late 2005 Puresend replaced its appliances with Message Systems Delivery Manager, gaining a flexible, open framework that enabled per-client and per-domain throttling, IP segmentation for dedicated addresses, and optimized hardware choices. The change improved deliverability and continuity, simplified operations, cut the number of email servers by two-thirds and lowered IT costs while supporting rapid growth and tighter ISP compliance.
