Automate Slack Broadcasts and Blasts: Introducing Threadly Workflows

slack threadly app workflows broadcast messaging

Today, we're excited to announce one of our biggest updates yet: Workflows are now available to as a beta in Threadly!

If you’ve ever wanted to broadcast a message, blast a quick update across multiple channels, or offer proactive support inside Slack without manually typing every time, Workflows make it effortless.


Threadly’s new Slack workflows engine is built to help you automate Slack messaging at scale — faster, smarter, and more personalized than ever before.

Why We Built Workflows for Threadly in Slack

Slack is a powerful tool for team communication, but when it comes to proactive messaging, it can be clunky. You can’t always be online to send onboarding messages, post reminders, or prompt your community with updates.
That’s where Threadly comes in.

With Threadly Workflows, you can now set up smart triggers and actions that automatically send messages exactly when you need them — without lifting a finger. Think of it like supercharging your Slack broadcast power with precision timing and targeting, all with the Threadly magic like actions, forms, and more.

How Threadly Workflows Work

Setting up a Workflow in Threadly is simple:

  • Choose a Trigger: Pick the event that should kick things off. (Example: A user joins a channel or a new channel is created.)
  • Define an Action: Decide what happens next. Send a Slack message, launch an interactive form, or kick off a custom CTA (call-to-action).
  • Activate: Sit back and let Threadly automatically blast your interactive message exactly when it matters.

There are so many incredible use cases: 

✅ Welcome new users the moment they join a channel
✅ Remind teams about important deadlines
✅ Share onboarding checklists for new projects
✅ Drive event signups with automatic messages
✅ Deliver proactive support prompts to customers

How It’s Different from Native Slack Workflows

Slack does offer basic workflows, but Threadly Workflows are built specifically for broadcast and proactive support at scale.


With Threadly, you get additional power like:

  • Message blasts across multiple channels at once
  • Built-in forms and buttons to capture responses
  • Dynamic audience targeting
  • Easier setup with flexible templates

Threadly is designed for teams who use Slack not just for chatting, but for marketing, support, onboarding, and engagement — at scale.
