Proprietary Mail Transfer Agent Technology

SocketLabs’ proprietary mail transfer agent (MTA) technology provides robust intelligence and flexibility allowing us to perform rapid customization and high-scale execution of critical email deliverability components – including authentication, encryption, white-labeling, traffic-specific sending rules, and more. Whether delivered via our cloud-based solutions or our on-premises solutions (see videos below), we support the delivery of over one million messages per hour with virtually unlimited potential to expand.

This technology was architected by software engineers and insightful subject matter experts who understand the intricacies of email as a critical driver of business success. Our proven solutions have been used around the globe for more than a decade to deliver billions of transactional and marketing messages in support of virtually every industry and business use case.  Our control of the email delivery backbone allows us to easily adapt to the dynamic email ecosystem and be first-to-market with email deliverability and security innovations (most recently MTA-STS and secure engagement tracking) that promote greater brand protection and performance.
