Proprietary High-Speed MTA
We purposely build relay-only (i.e., send-only) MTA for the highest speed. The system is 100% built by our engineers with C/C++. It has been developed and fine-tuned for over decades. This MTA system is not only fast in sending mails, but also stable and reliable.
The typical configuration of on-premises MTA can send 5 million emails per hour, with the capability to go for higher volume by scaling up or out on servers, IP and bandwidth. Our managed cloud-MTA has the capacity of sending one billion email per day.
Amazon Cloud, Azure, Google Cloud and other major public cloud servers do not allow large volume (bulk) SMTP mail send out. However, with our “hybrid solution,” you can transfer mail list and content over our cloud-MTA without using SMTP. Your application can send high-speed mails without being limited by the cloud platform.
We provide four different infrastructures to accommodate to different requirements. Customization can be made to your specific framework’s needs.
- Web-based SaaS
- On-premises MTA
- Hybrid
- Dedicated Server
Our customer are all large enterprises, with a variety of needs in email sending and system architecture. Customers choose us because of our flexible MTA frameworks. The majority of them use our “hybrid solution,” which is quick and easy to set up and offers high-level information security.
