Hey @yuni yunan 

Welcome to the Klaviyo Community! Sorry to hear that you accidentally deleted your email template.

First thing to remember that only email templates from a Flow can be recovered. The quickest and easiest way to recover a template from a flow is to reach out to Klaviyo support. They will be able to help you recover it, just send the name of the email or the email ID (if you have it) with your initial ticket and they should be able to help you get it back into your account.

Thank you so much for being part of the Klaviyo Community!
