How to Send RSS Feed Updates to a Slack Channel

Short answer: You can send RSS feed updates to Slack in three main ways: Slack’s own RSS app, which posts new items to a channel after you add a feed with the /feed command; an automation platform that watches the feed and posts formatted messages; or a small script that posts to an incoming webhook. Use a dedicated channel, filter the feed by keywords so only relevant items arrive, and check occasionally that the feed still delivers.

Why teams pipe feeds into Slack

Most teams already live in Slack for most of the day. Asking people to open a feed reader, a news site or a competitor’s blog separately rarely works for long. Bringing new items into a channel where people already are is one of the lowest-effort ways to keep a team informed.

Typical uses include:

• Industry news for marketing, sales and leadership teams.
• Your own content, so colleagues know when a new article or product page is live and can share it.
• Release notes and status pages of tools the team depends on.
• Mentions of your brand or products on sites that publish lists of articles.
• Job boards, tenders or grant announcements for business development teams.
• Security advisories for developers and IT staff.

The common thread is information that arrives irregularly and matters to several people. A feed in a channel beats every person checking the same sources individually.

Option 1: Slack’s RSS app

Slack offers an RSS app in its app directory. Once a workspace admin has installed it, you can type /feed subscribe followed by the feed URL in the channel where updates should appear. /feed list shows current subscriptions, and /feed remove with the subscription ID stops one. Check Slack’s help centre for the current commands, because app details change over time.

Strengths: no extra accounts, quick to set up, free within Slack’s normal plans.

Limitations: little control over message formatting, no filtering by keyword, and you depend on the app’s check interval. It works well for low-volume, high-relevance feeds, such as a vendor status page or your own blog.

Option 2: An automation platform

Platforms such as Zapier, Make, IFTTT or a self-hosted n8n can watch a feed and post a message to Slack for every new item. The workflow usually looks like this:

1. Trigger: “New item in feed” with the feed URL.
2. Optional filter: continue only if the title or description contains certain words.
3. Optional formatting: shorten the description, add an emoji or a label for the source.
4. Action: “Send channel message” to the chosen Slack channel, often as a bot user with a custom name and icon.

Strengths: flexible formatting, filters, and the ability to do more at the same time, such as logging items in a spreadsheet or creating a task.

Limitations: costs usually grow with the number of tasks, polling intervals on cheaper plans can be long, and every workflow is one more thing to maintain.

Option 3: Incoming webhook and a small script

Developers can create a Slack app with an incoming webhook, which gives a secret URL that accepts JSON messages for one channel. A scheduled script reads the feed, remembers which item IDs it has already posted and sends new ones to the webhook. This gives complete control over formatting, deduplication and scheduling, and costs nothing beyond hosting.

The trade-off is maintenance. Someone has to own the script, handle errors, store state reliably and keep the webhook URL secret. For a technical team with many feeds this can be the cleanest option; for a small business it is usually overkill.

Comparing the three approaches

What a good feed message looks like

When you control the formatting, a few choices make feed messages far easier to scan in a busy workspace.

• Source first. Start the message with a short label for the source, such as the site name in bold. People decide in a second whether an item is relevant, and the source is often the deciding factor.
• Linked title. Make the item title the link, rather than pasting a long URL on its own line. Slack will usually unfurl a preview anyway.
• One or two lines of summary. Truncate descriptions to around 200 characters. Full article text in a channel is overwhelming and rarely read.
• Consider turning off unfurls. If previews make each message huge, disable link unfurling for the bot so the channel stays compact.
• A consistent bot identity. Give the posting bot a clear name, such as “News bot”, and an icon, so nobody confuses automated items with messages from colleagues.

For high-volume sources, consider a digest instead of individual messages: one message each morning listing the previous day’s matching items. Automation platforms can do this by collecting items and posting them on a schedule, and it dramatically reduces notification noise while keeping the information available.

Finally, think about who gets notified. Feed channels should almost never use @channel or @here. If an item is urgent enough to interrupt people, it probably belongs in a separate alerting process rather than a news channel.

Keeping the channel useful instead of noisy

The biggest risk with feed channels is not technical. It is that the channel becomes so noisy that everyone mutes it within a month. A few habits prevent that.

• One channel per purpose. Keep feeds out of discussion channels. Name them clearly, for example #feed-industry-news or #feed-competitors, so people know what to expect and can choose to join.
• Filter hard. A general news feed can publish dozens of items a day. Keep only items with your product names, market terms or competitor names, and exclude recurring noise such as sponsored posts.
• Merge related sources. Five separate subscriptions for five sites produce five kinds of formatting and often the same story several times. A merged feed with duplicates removed is calmer.
• Review quarterly. Remove sources nobody reacts to. If nobody has clicked a feed’s items for months, it is probably not needed.
• Use threads for discussion. Ask people to discuss an item in a thread so the channel stays scannable.

Feeding Slack from sites without RSS

Many useful sources have no RSS feed: a regulator’s news page, a supplier’s announcements, a local news site or a competitor’s press page. Neither the Slack app nor most automation platforms can watch such pages directly.

Feeds solves this first step. Paste the address of the page that lists the items, check the preview of what was found, and you get an RSS feed link with titles, images, summaries and dates. You can merge several sources into one feed, keep only items that contain (or leave out items that contain) your keywords, and duplicates are removed automatically. The feed refreshes on its own, and paid plans send an alert if a feed stops finding items, which matters for pages that change their layout. The feed link then goes into /feed subscribe or your automation workflow like any other feed. You can start on the free plan; see the plans for refresh intervals and limits.

Troubleshooting: when updates stop arriving

1. Open the feed URL yourself. If it shows an error or old items, the problem is the source, not Slack.
2. Check whether new items actually exist. Quiet periods are normal for some sources.
3. Look at the subscription or workflow history. Automation platforms show whether the trigger ran and whether the Slack step failed.
4. Check permissions. If the channel was renamed, archived or made private, or the connecting user left the workspace, posting can fail.
5. Look for duplicates logic. If the source changed item IDs, a tool may think everything is old or everything is new.

The bottom line

Sending RSS updates to Slack is a quick win for keeping a team informed. Start with Slack’s RSS app for simple, low-volume feeds, move to an automation platform when you need filters and formatting, and use a script only if you have a developer to own it. Whatever you choose, give feeds their own channels, filter aggressively and review the sources regularly so the channel stays worth reading.

FAQ

Is the Slack RSS app free?

The RSS app is available to Slack workspaces as part of the normal Slack plans, though a workspace admin may need to approve installing it. Check the app directory in your workspace for current details.

Can I filter RSS items by keyword in Slack?

Slack’s RSS app does not offer keyword filters. Use an automation platform with a filter step, or filter the feed itself before subscribing, so only matching items reach the channel.

How quickly do new feed items appear in Slack?

It depends on how often the tool checks the feed. Delays of minutes to an hour are common, and cheaper automation plans may check less often.

Can I post one feed to several channels?

Yes. Subscribe the same feed in each channel, or add several Slack actions to one workflow. Consider whether every channel really needs every item, though, and filter per channel if not.

What if the website I want to follow has no RSS feed?

Create a feed from the page that lists its articles, then subscribe to that feed in Slack. This works for news pages, blogs, job boards and similar list pages.
