Email notification regarding Login & Register can be found in WP Dashboard -> Cariera -> Settings -> Login & Register. These emails have been added on this tab due to them being conditional based on the user approval.
All other emails can be found in WP Dashboard -> Cariera -> Settings -> Emails where you will be able to enable/disable them as well as change their content.
You will only be able to edit emails sent from the theme from here and not WPJM handled emails
