What is SMTP2GO?

SMTP2GO is a cloud-based outbound email service designed to handle every aspect of sending and tracking your emails. Whether you need a free smtp relay for low-volume transactional messages or a scalable platform for large marketing campaigns, SMTP2GO takes care of the heavy lifting—routing mail through redundant data centers, monitoring delivery status, and alerting you to any issues.

SMTP2GO Overview

Founded in 2010, SMTP2GO set out with a clear mission: eliminate the common pain points of email delivery. Early on, the team recognized that many ISPs and hosting providers offered SMTP services as an afterthought, leading to unreliable throughput and unpredictable throttling. SMTP2GO built a global, multi‐data‐center infrastructure to guarantee uptime—even if one node goes offline, your emails keep flowing.

Over the years, SMTP2GO has grown from a niche tool into a full‐featured platform. Key milestones include the launch of visual reporting dashboards in 2013, introduction of advanced spam filter testing in 2016, and the rollout of dedicated IP and subaccount management in 2019. Today, businesses of all sizes rely on SMTP2GO for seamless email delivery and deep insights.
