What is Transactional Messaging?
Transactional messages are system-triggered communications like account verification codes, password resets, payment confirmations, shipping alerts, or compliance notices. These are not optional updates; they must arrive instantly, reliably, and securely. Unlike promotional or marketing sends, transactional flows are bound by higher expectations for deliverability, regulatory compliance, and fail-safe reliability.
SuprSend provides developer-first infrastructure designed to meet these exact standards.
