5 things to ask Claude before you send a WhatsApp broadcast

A WhatsApp broadcast is easy to send and hard to take back. A bad template, a list with people who never agreed, or a brand-new number sending thousands of messages on day one can get a number flagged.

If you run your WhatsApp Business account through an AI assistant, you can use it as a checklist before anything goes out. Here are five prompts worth asking every time. They work in Claude, ChatGPT or Claude Code once your assistant is connected to SendFromChat.

1. "Show me the preview first"

Send the weekend offer template to the "Weekend offer" list. Show me the preview before anything is sent.

The assistant shows the messages as they will actually arrive, with names and other fields filled in for real contacts, plus the number of people who will receive them. Look for an empty name, a placeholder in the wrong place, or a count that is larger than you expected. This one prompt catches most mistakes.

2. "Who on this list is opted out, and who might never have agreed?"

Anyone who replied STOP is skipped automatically, and stays skipped until they reply START. That protects you from messaging people who have already said no.

It can't tell you whether a contact ever agreed in the first place. Meta expects people to have agreed to receive WhatsApp messages from you, so ask yourself where each list came from. If you're unsure, read how to collect and keep opt-in first.

3. "How many days will this take?"

If your number hasn't sent in bulk before, the first days are capped at 50, then 100, then 200 people a day, so WhatsApp doesn't see a number that suddenly sends thousands. The preview tells you how many days your list will need.

A list of 600 on a new number is a multi-day send. Knowing that up front beats finding out halfway through. The background is in bulk messaging without getting banned and messaging limits.

4. "Is this template likely to be approved?"

Business-initiated messages go out as templates, and Meta reviews them. Ask the assistant to draft one and check it against Meta's rules before it is submitted. Approval usually takes minutes, sometimes up to 24 hours, so submit it before you need it. See what Meta looks for in a template.

Include a clear way out, such as "Reply STOP to opt out". It helps your recipients and it keeps people from reporting you instead.

5. "Schedule it for when people are awake"

Schedule it for Thursday at 10:00 Amsterdam time.

Sending at a sensible local time is kinder to your customers. Anyone who replies opens a 24-hour window in which you can answer freely (how the window works), so send when you can actually reply.

The same checklist in the dashboard

You don't need an assistant for any of this. The dashboard has the same preview and opt-out handling, and there is a REST API if you'd rather send from code. The full walk-through, from spreadsheet to send, is in send a WhatsApp broadcast from a spreadsheet.
