As answered by people managing Readless and eM Client.
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.

Was subscribed to like 12 newsletters and never actually read any of them. Felt bad about it every morning. Forwarded everything to Readless about two months ago and now I just get one email at 7am with the stuff that...
If you have multiple email accounts and want a neat way to organize them, eM Client can be a good option to consider. It has a few unique features, such as the Sidebar view, which can help provide context and improve...
One point in eM Client’s favor is its free version. However, its features are pretty limited. For example, you can only use it with two email addresses, and the only customer support option is the user forum.
EM Client is a strong competitor of Outlook that has a easy-to-use interface. This application helps you to manage email, calendar, contacts, and tasks. It can be used for Windows and Mac.

Also, if you're also trying to use Xtra email in Microsoft Outlook, also expect problems. Outlook is also crap. There are other email application options. Em Client (emclient.com) is an excellent alternative to Outlook. Source: about 3 years ago
Totally agree on the security risk. On the other hand setting up, maintaining and explaining PGP for non-technical users usually leads to not using encryption at all, which is by far less secure than a self-managed PGP gateway on a... Source: over 4 years ago
