Convert newsletters to RSS
With a bit of trickery you can convert most newsletters (Morningstar, ISW, etc.) to an RSS feed using https://emailtofeed.com There is some interesting investing info only available in newsletter format, and some websites like the ISW publish a newsletter rather than RSS Feed. In some cases you may need to use a throwaway GMail account and configure forwarding addresses to bypass various newsletter providers’ checks. I would not put any personal information into Newsletters you send here since they are essentially exposed to the internet without password protection (and anyone can fire a malicious email at those addresses).
