Proper implementation of 'Forward to A Friend' functionality. There was previously a 'Add Email to a friend' suggestion that is classed as 'Complete' but the current implementation is poor. A better and more comprehensive implementation has been done by MailChimp (https://mailchimp.com/help/add-the-forward-to-a-friend-link/) I love MailPoet but its sad that such an important feature implemented by a competitor has been overlooked - I might have to switch.
