The 24-hour window
When a customer messages you, a 24-hour window opens. Inside that window, you and your agent can reply freely, and every new customer message resets the clock. Most of your agent’s work (answering questions, following up an active conversation) happens inside this window.Outside the window: templates
Once 24 hours pass with no customer message, reaching out requires a message template: a pre-approved message format reviewed by Meta. Templates are how re-engagement and proactive follow-up work on WhatsApp, and Meta charges for them by category (marketing, utility, authentication) at rates that vary by country. Ciarem uses approved templates when reaching someone outside the window (for example when sending a template to a contact or list), and those Meta charges are drawn from your WhatsApp wallet at Meta’s cost, with no markup.What this means in practice
- Replies inside an active conversation: no Meta charge
- A follow-up the day after a customer went quiet: template, Meta charge applies
- Instagram DMs and Messenger chats: no Meta charges at all
