WP Lucky Wheel Emails not sending

Hi,

We are using WP Lucky Wheel and noticed the emails are not sending out after the wheel has been spun.

This is affecting both the customer emails and the admin notice emails.

I also noticed when we look at the “Emails” section of the plugin in wordpress, it only registers new email addresses not ones that have already been logged in there.

Is it possible to record all email address even if they have spun the wheel a few days back?

Thanks.
