 ## Why
 
 Newsletters pile up in email, and an e-reader is a much better place to read them. A Kobo doesn't do email, but it does sync with Instapaper, though only for articles saved by web address. Emailing a newsletter to Instapaper doesn't work. So InboxInk puts each issue on a web page of its own and saves that address.
