I apologize for the trouble with the Zap. Based on the screenshot, it looks like the email data mapped in the MailerLite action step is not available or doesn’t exist. Could you please try these troubleshooting steps for me?
Turn off the Zap.
Load in a new sample data in the trigger. (view larger)
Choose the new/recent sample data.
Remap the data in your MailerLite action step.
Test the action step again.
Publish the Zap.
Please give that a try, and keep us posted! 😊
