Does high open rate guarantee good deliverability?

Myth: False. High open rate does not guarantee good deliverability. Opens can be inflated by bots, MPP, and security scanning. Real deliverability depends on multiple factors beyond apparent opens.

High opens with high complaints, poor authentication, or list quality issues still face filtering. Opens are one signal among many in reputation assessment.

Use open rates as one indicator, not the only one. Monitor deliverability through inbox placement tests, complaint rates, and engagement beyond opens.
