Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-)
.
I saw the screenshot you attached.
1)The hover effect is from the product style you can change the product styles from Theme Settings >> Shop >> Product Styles.
Screenshot for Clarification: https://ibb.co/7J5Ndv4
If you want to hide the button then you can try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.woodmart-add-btn.wd-add-btn-replace {
display: none;
}
2) And for the auto responder please provide a relevant screenshot of the specific area to check it myself and help you out accordingly.
Best Regards.
