Send email not working and how to save a list as a guest

As a guest, I added some items to the list and see the following two problems:
1.) When I click on the “send email” button, nothing happens. I checked the spam/junk folders of the email address the list should have been sent to and the admin email address but never received the email notification.
2.) There isn’t a way to “login/register to save this list” from the https://sensonics.com/quote/ page without losing the items already added to the list.

Thank you in advance for your help!
