How does schema markup affect tab placement?

Schema markup provides structured data that helps Gmail understand your content:

Proper schema for transactional messages (orders, flights, events) may improve Updates tab classification rather than Promotions.

Schema enables rich features like action buttons, event cards, and quick views that enhance user experience.

Schema does not override classification algorithms. Marketing content with schema is still marketing content.

Use schema to help Gmail understand what your message actually is, not to manipulate perceived classification.

Proper cargo labeling helps port officials sort correctly. It does not change what the cargo actually is.
