if you don't want to give your email address or fill your inbox with newsletters, you can get them in your RSS feeds.

I just added this feature a few weeks ago to the RSS reader i built (https://aktu.io/about).

Right now there's a few hundreds newsletters you can subscribe to, i'm adding new ones every day, and suggestions i welcome :-)

You can subscribe to a newsletter as you would add a RSS feed, it's gonna showup in your folders, no need to give your email address.
