Native formatting

Posts that look native, not pasted

Cross-posting the same text everywhere produces broken Slack posts — truncated mid-word, missing media, wrong aspect ratio. Feedloop reshapes the post to Slack's native format before it ships. Specific to Slack: 4000 chars body, text only.

FAQ

Slack auto-poster questions

Does Feedloop really publish directly to Slack?
Yes — we use Slack's official API, not a browser automation hack. Your post lands the same way it would if you'd opened the Slack app and tapped Publish.
Do I need a Slack business account?
No. Any active Slack account works. Just connect it once via OAuth.
What does it cost to schedule Slack posts with Feedloop?
Feedloop has a free tier you can use to schedule Slack posts. Paid plans unlock higher volume and additional connected accounts. We accept USD via Polar and Ethiopian Birr via Telebirr.
Can I auto-post to Slack from an RSS feed?
Yes — Slack is a text-first surface and any RSS feed works directly. Image previews are auto-unfurled from links. When publishing does happen, Feedloop auto-truncates at word boundaries to fit Slack's character limit and dedupes by feed item ID so the same entry never ships twice.
How is this different from Buffer, Hootsuite, or dlvr.it for Slack posting?
Buffer is composer-first — you still write every Slack post by hand. Hootsuite is enterprise-priced with team workflows we don't try to match. dlvr.it has the same RSS-first shape Feedloop does but no MCP support. Feedloop's wedge is RSS-driven automation + native Slack formatting + a Model Context Protocol server that lets Claude / ChatGPT / Cursor / Gemini drive your Slack pipeline directly.
Can Claude or ChatGPT schedule Slack posts for me?
Yes. Feedloop exposes its publishing tools through the Model Context Protocol (MCP), so any MCP-compatible AI client — Claude (web, desktop, code), ChatGPT, Cursor, Gemini, Windsurf, VS Code, Cline, Codex, LM Studio, Cherry Studio, Jan, AnythingLLM — can draft and schedule Slack posts on your behalf. You authorize the connection once and the assistant can queue, reorder, or publish to Slack without you switching tabs.
What happens if a Slack post fails to publish?
The worker retries with exponential backoff before surfacing the failure for manual review. You'll see the exact Slack API error message in the queue and can either retry, edit the post, or remove it. Token-expiry failures auto-trigger a refresh through OAuth — you only get a re-auth prompt when the refresh itself fails.
