SMTP2GO Overview

Founded over a decade ago, SMTP2GO’s mission has always been to eliminate email delivery headaches. The original goal was simple: give developers and marketers a stable alternative to ISP mail servers that often imposed harsh throttles and lacked transparency.

Over the years, SMTP2GO expanded from a handful of data centers to a globally distributed network. Today, redundancy across multiple regions guarantees that even an internet outage won’t interrupt your email flow. From humble beginnings to serving thousands of businesses worldwide, SMTP2GO continually innovates its reporting, testing, and support features.

With a focus on reliability, SMTP2GO also introduced real-time bounce tracking, spam complaint alerts, and unsubscribe management long before many competitors. Those growth milestones cemented its reputation as a best-in-class free smtp relay solution.
