Can you automate messages in Slack?

Quick Answer: Yes. Slack provides Workflow Builder, a built-in no-code automation tool for creating scheduled messages, form-triggered responses, and multi-step workflows. Additional automation is possible via Slack's API, Zapier, Make, and other integration platforms.

Automating Messages in Slack

Slack offers multiple automation methods as of April 2026: the built-in Workflow Builder (available on all paid plans), the Slack Platform for custom functions, and third-party integrations through Zapier, Make, and similar tools.

Workflow Builder (Built-In)

Workflow Builder is a no-code tool accessible from Slack's left sidebar under Automations:

Available Triggers

  • Webhook — Start a workflow from an external HTTP request
  • Scheduled — Run at specified times (daily, weekly, custom cron)
  • Emoji reaction — Trigger when a specific emoji is added to a message
  • Channel join — Trigger when a member joins a channel
  • Shortcut — Manually triggered from the message compose area

Available Steps

  • Send a message — Post to a channel or DM with formatted text and variables
  • Collect information — Display a form to gather input from a user
  • Send an email — Send an email to specified addresses
  • Insert a channel bookmark — Add a link to the channel bookmarks bar
  • Set channel topic/purpose — Update channel metadata
  • Create a channel — Spin up a new channel programmatically

Common Automation Patterns

Daily Standup Collection

  • Trigger: Scheduled daily at 9 AM
  • Step 1: Send a form to team members asking for yesterday's work, today's plan, and blockers
  • Step 2: Compile responses and post a summary to #standup channel

New Employee Welcome

  • Trigger: Member joins #general or #new-hires
  • Step: Send a welcome DM with onboarding resources and key channel links

Incident Response

  • Trigger: Emoji reaction (:rotating_light:) added to a message
  • Step 1: Create a new #incident channel
  • Step 2: Post the flagged message to the incident channel
  • Step 3: Notify the on-call team via DM

Third-Party Integrations

  • Zapier — 30+ Slack triggers and actions, connecting to 9,000+ apps
  • Make — Slack module for sending messages, managing channels, and processing events
  • n8n — Self-hosted option for Slack automation with custom code

Slack Platform (Developer)

The Slack Platform allows developers to build custom functions in TypeScript/JavaScript (Deno runtime) that run on Slack's infrastructure. These functions can be combined with Workflow Builder triggers for custom automation logic.
