Replace Pocket and Feedly.
If you're trying to find a single app that helps you read RSS feeds and save URLs for reading later, BlogInMail can help, and it's only €18 / year.
There's an API, a bookmark button, and a Zapier integration to allow you to save URLs that are not a part of any feed or website, so you can get them on your next Daily Digest.
How does BlogInMail help?
By treating blog articles as "simple" URLs, you can get the best of both worlds, and a single email per day with "all you wanted".
Try it out. You'll see it's a great way to read a lot without interruptions or feeling overloaded.
