If I use the NPS Snippet provided by voice of the customer, it appends ?a=[n] to the link in the email where [n] is the value that the user clicked on. It doesn't however set the value of the NPS slider when the webpage is loaded.
Any suggestions as to how I might get this to work properly? It's nice to be able to have the buttons inline in the email, but pointless if the user then has to enter the value again on the website.
