How Schedchie handles Slack

Slack’s own install screen
You choose the workspace and the channel on Slack’s screen. There is no token to paste and no webhook to copy.
One connection per channel
Each connection posts to one channel. Connect again for the next one, in the same workspace or another.
A link to every message
Each published post carries its Slack link, one click from the calendar to the message in the channel.

Announcements in the same batch

Connect each channel once. From then on Slack is another row in the same weekly batch as your social accounts, with its own text where you want it: the release note in #announcements on Monday, the meetup reminder in #general on Thursday, the details in the thread.

Slack posting record

Schedchie reports no Slack figures. It keeps the record instead: what went out, when, to which channel, with the link to each message.

Slack is included in the flat €9.99 plan: up to 15 accounts, no post limits. Ultra (€24.99) covers unlimited accounts.

Slack questions

Where do I pick the Slack workspace and channel?

On Slack’s own install screen, when you connect. Then write the post and pick the time, and Schedchie posts there at the time you set.

Can I connect several channels or workspaces?

Yes. Each channel is one connection, so connect again for the next one, in the same workspace or another. Pro covers up to 15 of them, Ultra unlimited, with no per-account fees.

What is the thread reply?

An optional second message that Schedchie posts in the thread under your post, right after it goes out. Put the sign-up link or the long version there and keep the channel to one short message.

Can I turn link previews off?

Yes, for each post. With previews off, a link stays a link and Slack draws no preview under it.

Can it send direct messages?

No. Schedchie posts to channels only.

Can I schedule Slack with my other platforms in one place?

Yes. Schedchie is one social media scheduler for 20 platforms: Instagram, Facebook, TikTok, LinkedIn, Pinterest, YouTube, Threads, Bluesky, Mastodon, Telegram, Google Business Profile, Discord, Slack, WordPress, Dev.to, Hashnode, Ghost, Pixelfed, Listmonk and X (posting to X is paid in X credits, from €4.99). Pro is €9.99 a month for up to 15 accounts on each, 300 in all, with no post limits.

Can I schedule Slack messages from ChatGPT or Claude?

Yes, on every plan from €9.99, trial included. Point Claude, ChatGPT, Cursor or VS Code at mcp.schedchie.com and sign in on Schedchie's own page; your assistant can schedule, edit and retry Slack messages. Claude gets up to 88 tools, ChatGPT a core set of 14 (scheduling from ChatGPT needs its Business, Enterprise or Edu plan).
