Will inbox placement be based entirely on brand trust?

Brand trust already influences inbox placement through reputation systems, but "entirely" overstates the shift. Technical factors, real-time engagement, and per-message evaluation will remain alongside brand-level signals.

Brand trust components: domain reputation, historical complaint rates, authentication consistency, and subscriber relationship quality. These already heavily influence placement. Strong brands with poor current practices still face filtering.

What won't change: individual message evaluation, recipient-specific preferences, and real-time engagement signals. Even trusted brands sending suddenly irrelevant content see reduced placement. Trust establishes baseline; ongoing behavior determines actual results.
