Tips for WhatsApp
- WhatsApp only delivers broadcasts through a template it approved. Write the template once with a {{1}} variable, and every post fills it.
- Line breaks are not allowed inside the variable, so the message shows as 1 paragraph. Write 1 tight paragraph.
- Meta charges your WhatsApp Business account per conversation and per country. A broadcast to 200 people opens 200 conversations.
- Only message people who opted in. When too many people block you, Meta lowers how many messages your number may send.
Example WhatsApp post
1 warm paragraph with real news and a next step. It becomes the {{1}} variable of the approved template. This is sample text to show the format, not a real customer post.
Checklist before you schedule a WhatsApp post
- The text is under 1,024 characters for WhatsApp.
- No more than 10 photos or files are attached.
- The channel sits under the right customer, so approval rules apply.
- A time is picked, or the post uses the next free slot.
How approval, AI and reports work on WhatsApp
Approval. If the WhatsApp channel belongs to a customer with approval turned on, every post waits for a yes. The client sees a preview on a review link and can approve, ask for changes or comment. A post that is changed after approval goes back for a new yes.
AI. The AI assistant can fit a post to WhatsApp, keeping it under 1,024 characters, in your brand voice. It can also translate it and write alt text for pictures. Nothing changes until you accept.
Analytics. Postozo does not read post results from WhatsApp, so there are no WhatsApp numbers on the analytics page. You can still count clicks on your links with short links.
Bulk upload. Plan many WhatsApp posts in a spreadsheet and upload them as a CSV file with bulk upload: up to 500 lines, each checked against WhatsApp's rules before anything is created.
Client reports. WhatsApp posts are counted in client reports, without network numbers, because WhatsApp does not share them.
Client accounts. A client can connect their own WhatsApp account from a client connect link, filling in Access token, Phone number ID, Approved template name, Template language code, Recipients on the link page, so no password changes hands.
