Yes, Readless fully supports Lenny's Newsletter and it is one of the most popular sources consolidated by our product manager users. Subscribe using your @mail.readless.app address (or forward from Gmail with a filter) and Lenny's posts appear in your daily digest alongside Product Hunt, Mind the Product, and every other source. All full-length original posts stay linked inside the digest.
Yes. Pro users on Readless get 3 separate digests with per-schedule sender filtering, so you can route Sidebar and Muzli into a daily visual-inspiration digest, Lenny's Newsletter and Mind the Product into a weekly product-strategy digest, and Nielsen Norman and UX Collective into a weekly UX research digest. Each delivers on its own schedule and timezone.
Yes. Every design example, thumbnail, Dribbble shot, and image asset from your source newsletters is preserved in the digest, plus a direct link back to the original newsletter where you can view the full-resolution file, download assets, or see the full gallery. Nothing visual is lost in the summarization — the digest links back to every original source.
All of them. Readless processes Figma updates, Adobe Creative Cloud newsletters, Sketch product emails, Framer release notes, Webflow announcements, and any other tool newsletter you receive over email. If it arrives in your inbox, forwarding it to your @mail.readless.app address pulls it into the digest — there is no whitelist of supported senders.
Yes. The simplest option is to add your digest delivery email to a team distribution list (Slack email address, Google Group, or shared Gmail) so every team member reads the same consolidated brief. For tighter collaboration, create a shared team Readless account where multiple designers and PMs curate the same list of source newsletters and receive identical daily digests.
Your digest groups content by topic automatically. Visual inspiration (Sidebar, Muzli, Dribbble) lands in one section, product insights (Lenny's Newsletter, Product Hunt) in another, and UX research (Nielsen Norman, Laws of UX) in a third. Each section is scannable at a glance, so you can skip straight to whichever category is most relevant for today's work without hunting across sources.
Readless is a strong fit for design-system and frontend content. Smashing Magazine, CSS-Tricks, Frontend Focus, the Design Systems newsletter, and similar sources all consolidate cleanly into your digest. This is especially useful for designers who code, design engineers, and product designers who collaborate closely with frontend teams and want one feed that spans both sides of the stack.
Yes. Every design example in your digest links to the full original newsletter, so clicking through gives you the exact context to bookmark, save to Raindrop or Notion, or share in Slack. Your full Readless archive is searchable, so you can always come back weeks later and find that perfect pattern or inspiration you saw — no need to star emails or rely on memory.
