There is also https://blogtrottr.com/ which has a free plan with ads. It seems to update hourly on the free plan. (I used this service for years before creating my own, I can highly recommend it). Source: about 1 year ago

There are other services available as well. The keyword you are looking for is rss-to-email. I used to use https://blogtrottr.com/ for years before making my own and they have an ad-supported free tier if you prefer that. Source: about 1 year ago

I use RSS-to-Email then read them in my mail clients. Most things get routed to a few folders without notifications that I open when I want news. I'm using my own RSS-to-Email service https://feedmail.org but I've also used https://blogtrottr.com/ in the past. - Source: Hacker News / over 1 year ago

And you can get realtime RSS→email at https://blogtrottr.com/ for free (ads in emails). Or use some other RSS app. Source: over 1 year ago

I use my own RSS-to-Email service https://feedmail.org/. I've written about my setup and why I prefer RSS-to-Email on my blog nearly a decade ago https://kevincox.ca/2013/06/27/email-as-rss-reader/. I used to use https://blogtrottr.com which I do still think is a good product, they just didn't quite fit my needs so after about 8 years I ended up creating my own. - Source: Hacker News / over 1 year ago
