How long does Meta take to approve a template?

Usually minutes or hours. Meta reviews each template before approving it; once approved, you can use it in your campaigns.

How do I segment who I send to?

You choose the audience by tags or contact lists when you build the campaign, in the Campaigns menu. Tags are managed in Settings.

WhatsApp Campaigns: How to Send Bulk Messages with Templates

Q: Why can't I message a customer first with free text?

Because WhatsApp doesn't allow it. Every message that starts a conversation must be a template approved by Meta, with fixed content and variables like name or date.

TBit campaigns send bulk messages on WhatsApp. Meta requires approved templates to start a conversation. How templates and the 24-hour window work.

What it does

Campaigns send messages to many contacts at once: launches, promotions, reminders. The agent handles the replies one by one, like any conversation.

How it works

WhatsApp doesn't let you message a customer first with free text. Every message that starts a conversation must be a template approved by Meta, with fixed content and variables (name, date, value). Meta reviews each template before approving it, usually in minutes or hours. Once the customer replies, the 24-hour window opens and the agent chats freely.

You build the campaign by choosing a template and an audience (by tags or contact lists) and schedule it or send it right away. Replies arrive in the inbox and the agent handles them instantly.

Where to set it up

Templates: Settings, Templates section (create and send for Meta approval).
Campaigns: Campaigns menu (choose template, audience, schedule and see results).
Tags for segmenting: Settings, Tags section.

What NOT to put in the prompt

Nothing about campaigns: the prompt governs the conversation, not bulk sends. What does help is preparing the agent for the replies, for example a memory with the details of the promotion you sent, so it replies with real numbers.
