Question: True or false? Open rates are a reliable metric and can serve as the foundation of any deliverability strategy.
- True
- False
Explanation
Open rate can provide engagement context, but it is not reliable enough to anchor a full deliverability strategy. Opens depend on image loading, tracking settings, privacy filters, and non-human activity detection. HubSpot treats deliverability as a broader feedback loop that includes clicks, spam complaints, bounces, unsubscribes, and engagement quality. A stronger strategy uses multiple signals instead of relying on a single metric.
Why the other options are incorrect
True is incorrect because open data can be incomplete or inflated, so it should not be the foundation of deliverability decisions.
