With marketing events, you can store your customers' online and offline event data to track, compare, and evaluate your events as a strategy. Below, learn how to manually create a marketing event and import event participants. You can import existing contacts or new ones to associate them with the event. For example, you have ten existing contacts that you want to add as attendees to a specific event. You can import them with email addresses as event participants and retain their existing data because email addresses act as unique identifiers to prevent duplicates.

  • In your HubSpot account, navigate to Marketing > Events.
