Recent changes to spares order notifications would send emails when parts initially go on backorder. Although the email stated parts were on backorder it wasn't obvious in the email and it would be easy for customers to incorrectly assume their order was infact ready due to poor layout of the email.  Overhauled email notification so email subject and body content make it clear what is going on. Also modernised emails to look alot nicer with proper tables/styles etc.
