Sender Reputation

is a trust score assigned to a message sender by email service providers, mobile carriers, or messaging platforms, based on historical patterns of the sender's compliance behavior, engagement quality, and complaint rates. A positive sender reputation results in high deliverability — messages reaching primary inboxes or passing carrier filters without restriction — while a degraded sender reputation causes messages to be filtered as spam, blocked entirely, or subjected to reduced sending limits. Building and maintaining a strong sender reputation requires consistent use of permission-based contact lists, low complaint rates, appropriate message frequency, content quality, and compliance with platform-specific policies.
