# How can I use events & tags?

When events are created in Mailchimp you can see the activity on your customer activity feed.\
\
But this event also allows you to trigger a customer journey which you could use for thanking customers for making a special purchase (like a donation), collect reviews for specific products, or upsell.\
\
To trigger a journey from events:

* Go to Automations and [Build a new journey](https://us20.admin.mailchimp.com/customer-journey/create-new-journey/)
* Name your journey and select your audience
* Choose a starting point
* Select API & Integrations and then select Event API
* Build out the rest of your journey

Tags are created only one time, so can be used a little differently to events.\
\
Instead of triggering a customer journey when a tag is created, you can filter your audience by tags at a later date and use that segment to create a campaign.\
\
This can be great for capturing audience members with tags like “sale shopper” or “holiday buyer” with special campaigns.\
\
To create a campaign from tags:

* Create an [audience segment](https://us20.admin.mailchimp.com/audience/segments/) using a tag as your filter
* View your segment
* Send a campaign to your segmented customers

You can also trigger a journey on tag creation, similar to event creation above, for things like “new subscriber”.
