Transactional Email (Password Reset, Receipt)

User-action-triggered emails with an explicit functional purpose; the email *is* part of the workflow, not a marketing add-on.

Transactional Email

Examples. Password reset. Receipt. Online hotel check-in (e.g. room-key delivery).

Why it's Inter-page latency. The user is actively waiting for the email — anything slower than 10 seconds is a perceptible failure. Inter-page edge decisioning or direct-trigger flows are the appropriate technical choice (source.real-time-clarity-md).

Why it's NOT a marketing optimization. Transactional emails are part of the product. The CDP's role is to ensure the message goes out reliably, not to optimize click-through. Architectural decisions should keep this path simple and isolated from marketing optimization complexity.
