Hi [@Serhii\_](https://community.hubspot.com/t5/user/viewprofilepage/user-id/919822)

Integrating structured data markup into transactional emails to generate Gmail Summary Cards poses a challenge.

- Since Gmail’s Summary Cards rely heavily on structured data to extract key information, implementing this feature requires email platform support for embedding such markup, which appears to be a restriction.

This limitation is not unique to HubSpot, as many email platforms struggle with implementing structured data due to the complexities of email client rendering and security measures.

**Hope this helps - Happy to help further!!**  
**Thank you very much and have a great one!**  
**Warm regards**
