Launched over a decade ago, SMTP2GO began as a small project to improve delivery rates for transactional emails in Asia.

Since then, SMTP2GO has grown to serve tens of thousands of customers worldwide, including e-commerce stores, SaaS platforms, and marketing agencies. Its mission remains the same: to offer a universal outgoing email service that combines reliability, detailed reporting, and developer-friendly integrations.

Key milestones include the rollout of multi-data-center redundancy in 2015, the launch of real-time visual reports in 2018, and advanced spam filter testing in 2021. Today, SMTP2GO handles millions of messages daily, and its engineering team continually updates the platform to comply with evolving email standards.
