As answered by people managing Impact and Readless.
Readless's answer:
RSS readers like Feedly collect your sources but still make you read everything. Inbox filters move newsletters into folders without shortening them. Readless does the reading for you: it summarizes, removes duplicate coverage, and delivers one digest on your schedule. It handles email newsletters, native Substack, and RSS in the same place, writes in nine languages, and lets you run separate digests for separate parts of your life. Pro is $4.90/month; Max adds the Synthesis briefing and custom instructions for $9.
Readless's answer:
People who follow more than they can keep up with. That includes investors tracking market newsletters, engineers and founders following tech Substacks, operators watching several industry briefings, and anyone whose inbox has quietly turned into a backlog. If you subscribe to 10, 30, or more newsletters and open only a fraction of them, Readless is built for you.
Readless's answer:
It started with a full inbox and a simple problem: subscribing to good newsletters is easy, but keeping up with them is not. The writing you actually wanted gets buried under senders you meant to read and stories you already saw somewhere else. Readless was built to turn that pile into one short, organized read you finish, so following a source doesn't cost you an hour a day.
Readless's answer:
Most tools stop at collecting your feeds or summarizing one email at a time. Readless reads across everything you follow at once. It merges stories that several newsletters cover, strips the ads, and organizes what's left by topic, so you read one briefing instead of twenty emails. On Max, the Synthesis option goes a step further and writes a single connected story across all your sources, with citations back to each one. You can also read any source in your own language, out of nine options.

There are plenty of affiliate platforms. I use impact.com and I pay $500 a month plus initial setup fee. I offer 50% commission so I got over 200 partners who applied to help me sell my compliance software. I didn't have to do any leg... Source: almost 3 years ago
Otherwise, you can use CJ or impact.com, they are good ones as well. Source: over 3 years ago
Thanks but is it impact.com? If so, it says to talk with sales (no prices listed), usually meaning it's quite expensive haha. Source: over 3 years ago
