LinkedIn Newsletter and a regular LinkedIn post look similar from the outside — both show up in your feed, both come from your profile or Page — but they’re built on different systems underneath, and only one of them can be automated from RSS today.
A LinkedIn Newsletter is an extension of LinkedIn’s long-form Articles feature: subscribers get notified by email and in-app whenever you publish a new edition, and editions live in a dedicated newsletter archive separate from your regular post history. It’s built for recurring, subscriber-based long-form content — closer to a blog with a built-in subscriber list than to a normal social post.
LinkedIn’s official API has no endpoint for publishing Newsletter editions — a limitation that applies across every automation tool, not just PostRSS. LinkedIn’s Posting API covers regular posts to personal profiles and company Pages, including text, images, and video, but Newsletter editions specifically sit outside what any third-party tool can publish through official channels. That’s a platform limitation, not a gap in any particular auto-poster’s feature set.
Regular LinkedIn posts — to your personal profile or a Company Page — are fully supported through the same API and work with PostRSS today, on your normal RSS-to-social schedule. If your goal is getting new content in front of your LinkedIn audience automatically, a regular post pointing to your full article (on your own site) accomplishes that; it just won’t appear inside the Newsletter format with its dedicated subscriber list and archive.
Auto-post a summary and link to your full content as a regular LinkedIn post through PostRSS, and reserve manually-published Newsletter editions for when you specifically want that subscriber-notification format and archive — the two aren’t mutually exclusive, and most creators end up using both for different purposes rather than picking one.
No — LinkedIn’s API doesn’t expose an endpoint for publishing Newsletter editions, so no third-party automation tool can do this through official channels, regardless of which one you use.
Yes — that’s fully supported and works the same way as auto-posting to other networks, on the schedule you set.
No — Newsletters are built on LinkedIn’s Articles system with a dedicated subscriber list, email notifications, and a separate archive, while regular posts are the standard feed content type that auto-posting tools work with.
It depends entirely on whether LinkedIn adds a Newsletter-publishing endpoint to its public API — something outside any auto-posting tool’s control, since it requires LinkedIn’s own platform support.
LinkedIn Newsletter editions can’t be auto-posted from RSS by any tool, because LinkedIn’s own API doesn’t support it — not a limitation specific to PostRSS or any competitor. Regular LinkedIn posts to your profile or Company Page remain fully automatable, and combining automated regular posts with occasional manual Newsletter editions covers both formats without forcing a choice between them.
