Events can be tagged for tracking interactions of users and for API calls.
Add tags to your event when you first create it. Then, contacts that add themselves to your contact list while interacting with that event are automatically tagged with those tags.
Finally, when you send an email or SMS message to follow up on the event, you can easily reach the people who are most interested in that event.
Here is how you do it!
1. When you create an event, specify one of more tags.

2. Then, users view your event through one of our widgets, and decide to add themselves to your contact list.

3.If you view the new contact (in the Contacts tab), you will see that they have an 'auto tag' that matches the one you originally set on the event.

4. Then, when you send an email or SMS message, you can filter to send only to contacts tagged with that tag!
