Hi @Chasing Cards, 

Welcome to the Community! We are so glad you’re here. Sorry to hear that your Lists have been deleted!

Although you don’t have the ability to recover a deleted list, our wonderful Klaviyo Support members actually have the ability to do so on your behalf! If you’ve accidentally deleted a list or even a segment, I would suggest reaching out to Klaviyo Support and letting our team members know you are trying to recover a deleted list or segment with the name of the list or segment and the approximate date it was deleted in order to recover it in your account. Bonus points if you can include your Klaviyo Account ID/Public Site ID to make looking up your account easier too. 

Thanks for your participation in the Community!
