How to edit the template of the email auto-responder?

I really don't know what an email will look like when someone pays and receives the email.  Can you please help me with this? :):)  It seems that each time I follow instructions from the tutorials it all goes pear shaped.

To edit the template that is sent in the email auto-responder, you need to click on the email icon, you will find it on the top toolbar in the Form Builder:

A window will be shown, there you need to click on the edit button on the email auto-responder that you want to edit. 

Now, you will see the template of the auto-responder, there you are able to add custom text, change the font style, font size, add image, all the customization that you want. 

Once you finish you only need to click on the save button, the auto-responder email will be sent the same as you set up on this wizard. 

Hope this helps.
