At step 1 you fill in something in memory. You then return to display a
new page to the user. So between step 1 and step 2, all information in
memory is effectively lost. Once the user submits the form in step 2, it
might not even be the same process that is handling the reply, since web
servers can use multiple processes and/or threads to handle requests.
So you need to save the data after step 1. Since this a Django mailing
list, I'd suggest using a Django model and saving it to the database.
