What Would Be Involved: Newsletter to Archives?

What would be involved in order for clients to create their newsletter within WordPress Dashboard environment, send out the newsletter, and then have that newsletter automatically archive, as a PDF, onto a spot on their site, where folks can easily pull up to read.

I know, the first thing that hits me in my thoughts are, “Redundant: to properly execute both parts to the process means more work for the client – then the mailed newsletter becomes redundant (along with fruitless efforts to send it out/create and manage campaigns), because the PDF versions are now easily available online – for everyone.”

*I’ve been researching some of MailChimp’s WordPress Plugins, and I’ve found “MailChimp Archive to WordPress Plugin;” which allows the process to go backwards (starts out as a newsletter, then turns those articles into blog posts), but not quite what we’re looking for.

Do you guys have any suggestions for plugins or different ways to use newsletter plugins, to help this become an easier thing for them to work with? Thank you!
