Good catch, you’re right. Email newsletters are free, that part of the feature page is accurate. Web Feeds are actually a Premium Archive feature though, and the feature page just hadn’t been updated to reflect that. I’ve fixed the page so it says Premium Archive now. The pricing page and the Premium Archive page were already correct, so the bug was isolated to the Web Feeds feature page.
Page scraping is a lot more resource intensive than RSS fetching, so it’s reserved for paid tiers. If you want to try Web Feeds, Premium Archive is $99/year.
Thanks for flagging it!
