Long-tail reputation dynamics and monitoring
Message Business operates as a long-tail ESP whose reputation is not uniformly tracked by the largest mailbox providers' reputation networks. This asymmetry can be advantageous for small incumbent senders (less aggressive filtering), but also means organisations have limited access to aggregate reputation data and community intelligence. Senders relying on Sendethic should monitor their own sender reputation directly rather than assuming the ESP's general reputation reflects their mail quality.
