Connect your website’s RSS or Atom feed once and every new article, product or episode posts itself to Threads — in front of the Instagram audience you already built, with a clickable link preview and nothing to remember after you publish.
Threads arrived with something no new network has ever had: an audience on day one. It is built on Instagram identity, so the followers you spent years earning there are available to you here without starting again. For a publisher, that is the rarest thing in social media — distribution you do not have to rebuild.
The second reason is the format. Instagram has never been friendly to links: no clickable URL in a caption, one link in bio, and an endless workaround economy built around that limitation. Threads does not have that problem. A Threads post is text up to 500 characters, and a URL inside it produces a clickable link preview card.
That matters more than it sounds. It means a title-and-link post — the exact shape of an RSS item — is a native Threads post rather than a compromise. Everything RSS automation is built around works here without adaptation.
The third reason is simply that the work is repetitive. Announcing every publication by hand means switching apps, pasting, waiting for the preview and posting. It takes a minute and it is forgotten constantly. Your site already produces a list of everything you publish; PostRSS reads it and posts for you.
Three things are needed: an account to post to, permission to post, and a feed to read. In PostRSS the account is a Target and each automated post counts as one Task against your plan’s monthly allowance.
Threads runs on Meta’s Graph API infrastructure, the same platform behind Facebook Page publishing. Connecting is an authorisation step in PostRSS: you approve access to the Threads account you want published to, and no password is ever handed over.
The account you connect is the one tied to your Instagram identity, so the followers who see the posts are the audience you already have. Access can be withdrawn from your account settings at any time, which stops publishing immediately.
Paste the address of your RSS or Atom feed. On WordPress this is usually your domain followed by /feed/, and every category and tag has its own — /category/news/feed/, for instance. Shopify, Ghost, Substack, Blogger, PrestaShop and OpenCart all expose feeds, as does every podcast host and every YouTube channel. If you are unsure, open the homepage source and look for application/rss+xml.
Set filters if the account should carry part of your site rather than all of it, and set a publishing window if you would rather posts landed at particular hours. Both are covered in detail below.
Publishing on your site is then the only action required. PostRSS notices the new item, builds the post and publishes it. Your feed is checked every 5 minutes on every plan, and every 1 minute on Enterprise.
Worth understanding once, because it explains why Threads behaves slightly differently from a simple API.
Meta’s Threads API does not accept a post in a single request. It uses a container model: the first call creates a container specifying the media type — TEXT, IMAGE, VIDEO or CAROUSEL — along with the content, and a second call publishes that container. For RSS automation the relevant type is TEXT with a link, which produces the standard post with a preview card.
PostRSS performs both calls on your behalf, so from your side a post either appears or it does not; there is no intermediate state to manage. The reason to know about it at all is that occasional Threads publishing delays originate between those two steps rather than in your feed — useful to know when you are diagnosing a slow post.
A Threads post holds up to 500 characters, and a URL consumes part of that budget. In practice a headline plus a link fits comfortably; the limit becomes relevant only with unusually long titles.
PostRSS trims the title at a word boundary when a post would exceed the limit, and always preserves the link in full — a truncated URL is a broken post, and the entire purpose is sending people to your site.
Because the preview card carries your page’s open-graph title and description beneath the post text, information that did not fit in the post body is still on screen. The 500 characters are the introduction, not the whole message.
PostRSS sends the item’s title and a link back to the original page. Threads then builds a preview card from that page’s open-graph tags — the image, the title and the description your site already declares for sharing.
The appearance of your Threads posts is therefore controlled by your website. If a post arrives without an image, the article is missing an og:image, or the image is too large, or a CDN rule is blocking Meta’s fetcher. Fixing it at the source fixes every network at once, because Threads, Facebook, LinkedIn, Bluesky and Telegram all read the same tags.
Meta caches previews aggressively. If you correct an image and the old one keeps appearing, that is the cache rather than the automation; it clears on its own, and a changed image URL bypasses it.
This section is the one most worth reading, because it is where automated Threads accounts succeed or quietly fail.
Threads is a conversation-first network. Its ranking rewards posts that generate replies, and posts carrying an outbound link have generally travelled less far than posts that keep people in the app. This is not unique to Threads — every network prefers to keep attention — but it is pronounced enough that a purely link-posting account underperforms.
The pattern that works is to treat the automation as the reliable base layer rather than the entire strategy. The feed guarantees your account is never dormant and that everything you publish reaches the people who follow you. A human then does the part automation cannot: replying, asking the question your article raises, posting the occasional standalone thought.
Two concrete adjustments help considerably. First, a headline that reads as a statement or a question outperforms one that reads as a catalogue entry — and that lever is on your own site, in the title your feed emits. Second, filter harder than you would on a broadcast network: an account posting three genuinely interesting items a week does better here than one posting fifteen.
Most Threads accounts should carry a slice of a site rather than everything it publishes.
PostRSS applies filters before anything is posted. You can restrict a Target by category or tag, require a keyword in the title, or exclude one. Several Targets can run from the same feed with different rules, which is how one site feeds a main brand account and a specialist account without publishing twice.
A useful test before enabling anything: look at the last month of your feed and count how many items would have passed your filter. Given how the network rewards engagement over volume, a smaller number is usually the better answer.
PostRSS checks your feed every 5 minutes on every plan, and every 1 minute on Enterprise. That is how fast a post can arrive, not how fast it always should.
Two situations call for scheduling. An editorial team publishing six articles in one morning will otherwise put six consecutive posts into followers’ feeds within minutes — on a conversation-led network, that reads as flooding. And an audience concentrated in one region gets more from posts that land during waking hours.
PostRSS’s scheduling controls constrain when a Target may publish, holding items found outside the window and releasing them inside it. The feed is still checked at the same interval; only the release moves.
Blog articles with opinionated, readable headlines are the strongest fit, because they invite replies.
Podcast episodes work well and need no extra setup — every podcast is already an RSS feed, and the preview card renders the episode artwork.
YouTube videos post cleanly; every channel exposes a feed keyed to its channel ID.
Product launches suit Threads better than routine catalogue updates, given the Instagram-derived audience. Filter to launches and notable items.
Release notes and changelogs are the weakest fit of the common sources. They are better served by Telegram or Discord, where an audience specifically subscribed to that information is waiting.
A frequent assumption worth correcting: connecting Threads does not post to Instagram, and the two are not interchangeable.
They share an identity and a login, but they are different surfaces with different content models. Instagram is image-first and does not support clickable links in captions; Threads is text-first and does. An RSS item — a title and a link — is a native Threads post and is not a native Instagram post, which is precisely why Threads is the one that can be automated from a feed.
If your goal is an Instagram presence, an automated Threads account is a complement to it rather than a substitute.
Check that the Threads account is still authorised in PostRSS. Access can be withdrawn from your Meta account settings, and if that happened publishing stops even though the feed is still being read. Reconnect the account to resume. Also confirm the feed itself updated — a caching plugin serving a stale copy looks identical to a broken automation.
That is a filter behaving as configured. Review the category, tag and keyword rules on the Target.
No schedule is set on the Target. Add a publishing window.
Compare timestamps against your publication time. Under five minutes is the feed-check interval working as designed. Hours means the feed is cached, and PostRSS can only read what your server serves.
Open the article and inspect its open-graph tags. Threads renders what the page declares, and Meta’s cache can hold an old image for a while.
That is the 500-character limit. Shorten the headline on your site if the trimmed version reads poorly.
Threads shows views, likes, replies and reposts on each post, which is more per-post data than most networks give you. Views tell you the post was served; replies tell you it worked.
For traffic, add UTM parameters to your links so your analytics can separate Threads from everything else. After a month you will know how many sessions the account sends and whether those visitors behave differently from the rest of your audience.
The number to watch specifically here is replies per post. On a conversation-led network that figure predicts reach better than follower count does, and a consistent zero is a signal to tighten the filter or rewrite headlines — not to post more.
Each Threads account you connect is one Target, and each automated post is one Task against your plan’s monthly allowance. Paid plans raise both numbers and add the other networks, and they are chosen on postrss.com rather than inside the mobile app.
Because Threads rewards restraint, a well-filtered Target here is usually one of the cheapest you will run: three or four items a week costs fifteen or so Tasks a month.
Threads sits between the open networks and the large closed ones. Bluesky and Mastodon reach a smaller but more link-tolerant audience, and running one of them alongside Threads costs almost nothing extra.
Because Threads rewards a headline that reads as a statement, the lever is on your own site. How many items your feed carries and how its titles are written matter more here than any setting, and if you publish from WordPress, the PostRSS plugin makes filtering to your strongest categories a two-click job.
No. Connecting is an authorisation step, and access can be withdrawn from your account settings at any time, which stops publishing immediately.
Up to 500 characters. PostRSS trims the title at a word boundary if needed, always preserving the link in full.
Yes, provided the destination page declares open-graph tags. Threads builds the card from your page’s og:image, og:title and og:description.
No. Threads and Instagram share an identity but are separate destinations with different content models. Instagram does not support clickable links in captions, which is why an RSS item is a native Threads post and not a native Instagram one.
No. PostRSS publishes items that appear in the feed after the Target starts running.
Pause the Target in PostRSS, or withdraw the app’s access in your account settings. Either stops publishing immediately.
Connect the account, point it at the narrowest feed that still carries your best work, and set a publishing window. Watch replies rather than follower count for the first two weeks. If the replies appear, widen carefully; if they do not, tighten the filter and look at your headlines — on Threads, that is almost always where the answer is.
