If your customers reply to your broadcast, see and answer their messages in your Inbox. You'll also know which broadcast they're replying to so there's no guessing required from your agents.

Trigger automated flows.

If your customers reply to your broadcast, you can also make those replies trigger a flow, so your team doesn't have to manually reply.

Automatic retries.

If for some reason WhatsApp can't send your message, we'll automatically retry to help you reach your customers without requiring any action on your part.

Smart rate limiting.

WhatsApp allows a specific number of conversations opened in a day for each company. We automatically queue messages when we know we won't be able to deliver them.
