Lazy Loading affects Divi Contact Form Helper

The Divi Contact Form Helper provides a “confirmation email” function to respond to people filling out an on-line form. In the body of the confirmation email, if there is an image, the email will not actually be sent if SG Optimizer’s Lazy Load functionality is activated. I have tried the exception on the IMG tag by adding a class name to the tag and to the exception list in SG Optimizer, but that doesn’t result in the email being sent. ONLY turning Lazy Load off seems to work. My thought is that somehow Lazy Load is keeping the body of the confirmation email from loading so that the body appears empty to the form plugin and so no email is sent.

Am I putting the CSS class in the wrong place (i.e. it should not be on the IMG tag but further up the DOM hierarchy?)? Would there be another explanation to this maybe?

Thanks for any clarity you might be able to give as to how this is functioning under the covers.
