# engageMessageAdd

> Create a broadcast / engage campaign.

Pick a `method` (`email`, `messenger`, `push`, or `whatsapp`) and pass the
matching content field. Preview channel content first with
[`engageMessageSendTestEmail`](/api-reference/mutations/engageMessageSendTestEmail) or
[`engageMessageSendTestWhatsapp`](/api-reference/mutations/engageMessageSendTestWhatsapp) before sending to a real
audience.

<Info>
Estimate reach beforehand with [`engageAudienceUniqueCount`](/api-reference/queries/engageAudienceUniqueCount).
</Info>

<Note>
**Side effects:** When `startImmediately` is `true`, the campaign begins sending right away instead of waiting for its schedule or a later [`engageMessageStart`](/api-reference/mutations/engageMessageStart) call.
</Note>
