We can’t combine both the email and the events as both are separate.
1. Marketing emails - The Marketing Emails API can be used to programmatically create, update, and get details about marketing emails. You can also query details about the post-send statistics of a specific email or set of emails. These statistics should match what you can access in the app on the Details section of a particular email and will be returned under the stats object in your JSON response.
2. Marketing events - A marketing event is a CRM object, similar to contacts and companies, that enables you to track and associate marketing events, such as a webinar, with other HubSpot CRM objects. Below, learn more about working with the marketing event API to integrate marketing events into an app.
