# WhatsApp blasting

Reach customers on WhatsApp with two options under **Blasting**:

* **WhatsApp Business App** — for the standard WhatsApp Business setup. Write a free-form message, attach media if you like, and messages go out gradually (drip sending) to keep your number healthy.
* **WhatsApp API (WABA)** — for the official WhatsApp Business Platform. Select an approved **WhatsApp Template** and its language. A template with an image, video or document at the top comes with that file already attached, with a preview of what goes out; remove it to send a different file with this blast only. If that file is over WhatsApp's size limit, it shows in red and **Create** stays off until you replace it. See [The WhatsApp Templates library](/settings/whatsapp-template-library) and [Picture and file size limits](/settings/file-size-limits).

For both, pick the audience — filter your contacts (for example by label) or upload a list of people — and set the **scheduled time** for the send. You can also skip anyone who already received an earlier blasting or, on WhatsApp API (WABA), the template you are sending. See [Creating and scheduling a blasting](/campaigns/creating-and-scheduling-a-campaign).

WhatsApp requires pre-approved templates for proactive (outbound) messages on the official API, so prepare your templates first.

Tip: your AI agent can prepare a WhatsApp blasting draft for you to review and send — see [Prepare a WhatsApp blasting with AI](/ai-agents/prepare-a-whatsapp-campaign).
