# Broadcast invites to your entire Slack workspace

> Use Cake Day's broadcast feature to send a mass invite DM to every workspace member who hasn't opted in yet — available on Starter, Growth, and Pro.

Broadcast sends an invite DM to every workspace member who hasn't already opted in or explicitly declined. Instead of inviting people one by one, a single broadcast reaches your entire workspace in seconds.

<Note>Broadcast is available on **Starter, Growth, and Pro** plans. It is not available on the Free plan. [Upgrade your plan](https://cakeday.io/pricing) to unlock it.</Note>

## How to run a broadcast

You can start a broadcast from Slack or from the dashboard.

**From Slack:** Run `/cakeday broadcast` in any channel.

**From the dashboard:** Go to [cakeday.io/app/roster](https://cakeday.io/app/roster) and click **Broadcast**.

Either way, Cake Day opens a preview modal showing the exact DM that will be sent. Review it before confirming — once you confirm, the DMs go out immediately.

<Warning>Broadcast DMs go to everyone in your workspace who hasn't already responded to a Cake Day invite. Review the preview carefully before clicking confirm — there is no way to recall messages once they're sent.</Warning>

## Who receives the broadcast

Cake Day sends the invite DM to every workspace member **except**:

* Members who have already opted in and are on the roster
* Members who have previously clicked **No thanks** on an invite

If someone declined a previous invite, the broadcast will not re-invite them. An admin can still send them a manual invite via `/cakeday invite @user` if they change their mind.

## What recipients see

Each recipient gets the same friendly invite DM that a one-on-one invite sends:

* **Add my dates** — opens a modal to enter their birthday and optional work start date
* **No thanks** — records their decline

Once they respond, their status updates on your roster automatically.

## Audit logs

Cake Day retains broadcast logs for up to 12 months. You can use these logs to confirm when a broadcast was sent and which admin triggered it.
