customer receives deceptive site when trying to open Autoresponse email

See the attached screen shot that my customer received when she tried to open the autoresponse email that was sent from one of my jotforms.

 

What's happening?  Is there something I need to do to prevent this?

I'm sorry for any inconvenience, however, could you provide us the form that's having an issue with its autoresponder, please? Also, can you provide us the information stated if you click "Details" that's shown on the warning message. 

We will wait for your response. Thankyou.

This is the form:
https://form.jotform.com/60242720891957
It has a stripe integration to it, so it is possible that the stripe
'confirmation' is giving the error. I really don't know.

Unfortunately, I was unable to submit your form. However, I have cloned it and it clones the exact email template that you have in your form, I was able to open the email without any problem.

On the image that you shared us, please open the details and provide us the screenshot, it will help us to know what is generating the issue.
