Best newsletter digest apps: six honest ways to handle more newsletters than you can read

If 20+ newsletters arrive every week and most go unread, the fix is one of six tools — and they solve genuinely different problems. We checked every site on this page in July 2026 and quote only what each one actually says. Full disclosure: Weekly Brief (the last entry) is ours, and it's new. The other five are real options, and for some readers the better pick.

First: which problem do you actually have?

"Too many newsletters" is two different problems. If newsletters clutter your inbox, you want them moved somewhere better — a reader app or an RSS feed. If you can't read them all, moving them doesn't help; you need something that condenses the pile (a digest), or decides for you what's worth reading (ranking). Every tool below sits somewhere on that map.

Meco — a dedicated newsletter reading app

Meco calls itself a "newsletter aggregator built for reading": connect Gmail or Outlook (or use a dedicated Meco address) and your newsletters move into Meco's apps on iOS, Android, or the web, decluttering your inbox. Its feature set is real: smart filters and grouping, daily AI audio roundups of your newsletters, personalized newsletter discovery, and bookmarking with annotation.

Pricing: not published on meco.app as of July 2026 — the site's FAQ mentions a free option and a PRO plan (the Gmail/Outlook connection is part of PRO), but lists no price. Best for: people who want a reading home for newsletters and are happy to check one more app. Our longer take: Meco alternative.

Mailbrew — a multi-source digest you compose

Mailbrew is "your personal daily digest": you build a "brew" from sources you pick — newsletters, RSS, Hacker News, AI-picked top stories, stocks, saved links — and everything from them arrives as one email, daily or weekly. Its homepage cites 60,000+ users and over 7.5 million digests sent, and its changelog's latest entry (February 27, 2026) ends "we'll keep shipping."

Pricing (from its pricing page, July 2026): free plan — $0, one digest, 26 sources, includes ads; paid — $4.92/month billed yearly at $59, unlimited digests, all sources, no ads. Best for: scattered sources — feeds, stocks, HN and newsletters folded into one email you skim yourself. Our longer take: Mailbrew alternative.

Readless — AI summaries of everything

Readless turns newsletters, Substack publications, and RSS feeds into one AI digest — its homepage pitches "30+ sources" condensed into a roughly 5-minute read, delivered on your schedule, with duplicate stories across newsletters merged and ads stripped.

Pricing (from its pricing page, July 2026): Pro is $4.90/month after a 7-day free trial (card required); Pro includes up to 3 digest schedules, unlimited connected newsletter sources, a dedicated Readless email address, and native Substack and RSS support. A cheaper Lite plan is listed as "coming soon." Best for: people who want the content of everything in condensed form. The trade-off is inherent to summarizing: 25 newsletters in still means 25 summaries out — the deciding stays with you.

Kill the Newsletter — newsletters as RSS, free

Kill the Newsletter! is a free, donation-supported tool by Leandro Facchinetti that converts email newsletters into Atom feeds: create a feed, get an email address, subscribe to newsletters with it, and issues appear in your RSS reader. Honest caveats from its own FAQ: some newsletter publishers block its addresses (forwarding from your real email is the workaround), feeds can't be shared safely, and old entries eventually drop off the feed.

Pricing: free (Patreon / PayPal / GitHub Sponsors keep it running). Best for: RSS-reader people. If you already live in a feed reader, this plus a Gmail forwarding filter costs nothing and just works.

The Substack app — if your newsletters are mostly Substacks

Substack's own app (iOS and Android) collects your Substack subscriptions in one place, with the latest posts from writers you follow plus the platform's video, podcasts, and subscriber chats. No price is listed on the app page; paid Substack publications are their own separate subscriptions.

Best for: readers whose subscriptions are mostly Substack publications — it's the path of least resistance for those. It doesn't help with the rest of your newsletter pile, and it adds the discussion/discovery layer of a social app, which is either a feature or the exact thing you're escaping.

Weekly Brief — ranking instead of another app (ours)

Weekly Brief is our product, so judge this section accordingly — and we're new, so we won't pretend to a track record. It does one narrow thing none of the tools above do: it ranks. It reads your week of newsletters and delivers one short document — the two or three issues worth your time, each with a one-line reason, the rest listed below — into Readwise Reader, Matter, or your Kindle. No new app, no new inbox, nothing to check.

Pricing: free for up to 10 newsletters (one weekly brief, one delivery target, no card); $5/month for unlimited newsletters, daily or instant briefs, and multiple targets. Best for: read-later power users who don't want their newsletters moved, bundled, or summarized — they want the flood decided: "read these three, skip the rest."

All six at a glance

Which should you pick?

• Inbox clutter, want a reading home: Meco — or the Substack app if your subscriptions are mostly Substacks.
• Many source types, one email: Mailbrew — its free plan is a real free plan.
• Want everything, condensed: Readless.
• Live in an RSS reader, want free: Kill the Newsletter.
• Want the deciding done for you, in the app you already read in: Weekly Brief — one ranked brief a week into Reader, Matter, or Kindle.

Frequently asked questions

What is the best app for managing too many newsletters?

It depends on which problem you have. Inbox clutter and you want a dedicated reading app: Meco. Many sources bundled into one email you design: Mailbrew. AI summaries of everything: Readless. You read in an RSS reader: Kill the Newsletter, free. Your problem is deciding what to read: Weekly Brief ranks your week and delivers one short brief into Readwise Reader, Matter, or Kindle.

What's the difference between a newsletter reader and a newsletter digest?

A reader (Meco, the Substack app) is a separate place your newsletters live — you go there and read. A digest (Mailbrew, Readless, Weekly Brief) turns many issues into one periodic document. Within digests: bundling and summarizing give you everything in condensed form; ranking tells you which few issues to actually read.

Are there free ways to deal with newsletter overload?

Yes. Kill the Newsletter is completely free. Mailbrew's free plan gives you one digest from 26 sources (with ads). The Substack app covers Substack publications. Weekly Brief's free tier ranks up to 10 newsletters into one weekly brief. Meco has a free tier too, though its site doesn't publish the PRO price.

Does Weekly Brief summarize newsletters like Readless does?

No. Summarizing 25 newsletters leaves you 25 shorter things to read. Weekly Brief ranks: one short weekly list of the two or three issues worth your time, each with a one-line reason, the rest listed below so you can archive them without guilt.

Which newsletter digest tools work with Readwise Reader, Matter, or Kindle?

In this roundup, Weekly Brief is the one that delivers into Reader, Matter, or a Kindle directly. Both Reader and Matter also accept newsletters natively via their own forwarding addresses if you'd rather get every issue unranked — see our guides to newsletters in Readwise Reader and newsletters in Matter.
