WP Better Emails for better looking notifications to users
I recently came across a useful WordPress plugin that can be used with WPESTATE.
WP Better Emails http://wordpress.org/plugins/wp-better-emails/
All emails from WordPress (lost password, notifications, etc.) are sent by default in text/plain format. Same applies for WPESTATE.
WP Better Emails wraps them with a much better looking customizable HTML email template.
