Find Archived Campaigns

Hey @amanda.miller 

Welcome to the Klaviyo Community!

Archived campaigns do not show on the default Campaigns tab. To view them, go to the Options dropdown menu in the upper right-hand corner of your screen. Click View Archived Campaigns. 
There, you can also unarchive a campaign if you want, by clicking the Actions icon to the right of the campaign name and then selecting Unarchive. It should look like this:
 

For more information, head to How to Delete, Edit, View, Clone, or Archive a Campaign.

Hope this helps!
