Our Story
TosSend was born from frustration. As developers building products in Cambodia, we constantly struggled with email deliverability. International providers had high latency, limited regional support, and often flagged Southeast Asian IP addresses.
We knew there had to be a better way. In 2025, we started building TosSend with a simple goal: create an email API that just works for Cambodian developers. Regional servers, local payment methods, Khmer language support, and documentation that makes sense for our context.
Today, TosSend powers email for hundreds of businesses across Cambodia and Southeast Asia. From startups to growing companies, we help teams send transactional emails, marketing campaigns, and notifications with confidence.
