## Your distribution & follow-up plan

### Audience

Use the appropriate Slack Connect customer-channel group; check each shared channel is permitted for external announcements.

### Recommended action

Add a Slack form to capture structured feedback.

### Follow-up

Review form responses, route questions to the owner, and follow up personally where needed.

## Ready to send it to everyone?

Your free plan is ready to copy. To turn it into a real multi-channel broadcast with tracked CTAs and workflows, set it up in Threadly.

[Add Threadly to Slack](https://slack.com/oauth/v2/authorize?client_id=2573203509911.7020858675504&scope=channels:history,channels:join,chat:write,chat:write.customize,commands,files:read,groups:history,reactions:read,team.billing:read,team:read,users:read,users:read.email&user_scope=channels:read,channels:write.invites,chat:write,groups:read,groups:write.invites,im:write,mpim:read,mpim:write) [Open Threadly](https://app.trythreadly.com/app)

The planner does not automatically import your draft or send messages.

## How is this different from Slack Block Kit Builder?

Slack's Block Kit Builder helps developers design message layouts and export JSON. This free broadcast planner helps teams decide what to communicate, which audience needs it, what action to request, and how to follow up. It generates editable copy rather than executable Block Kit components.
