Do DKIM and DMARC improve inbox placement automatically?

Myth: False. DKIM and DMARC do not automatically improve inbox placement. They establish baseline trust and prevent spoofing, but placement also depends on reputation, engagement, and content.

Think of authentication as table stakes. Without it, you face serious problems. With it, you can compete. But having it does not guarantee winning.

Authentication removes obstacles and builds trust signals over time. Combined with good sending practices, authentication contributes to strong reputation that improves placement. But authentication alone is not magic.
