Who opened it, who bought, and who never wrote back
The day after each broadcast, you check just three numbers and change one single thing in the next one, not everything at once.

You sent the broadcast yesterday afternoon. Today you've got a new order or two, but you don't know if it came from that or would've shown up anyway. And a month from now, when the next one's due, you still won't know whether to repeat the same text or rewrite it from scratch.
You don't need to open some analytics dashboard to figure this out. You just need three numbers, and all three are right there in front of you, no digging required: who opened the message, who bought or asked something after opening it, and who still hasn't written back no matter what.
Just checking whether it "went well" doesn't tell you anything. What decides your next broadcast is figuring out where people got stuck among these three points.
Three numbers, not thirty
- 1How many opened it
WhatsApp marks the message as read if the customer hasn't turned off the double blue check. Count how many people on the list opened it in the first twenty-four hours; anyone who's turned off read receipts won't show up, so the real number is a bit higher. If far fewer people open it than usual, the problem isn't what you wrote inside: it's the timing you sent it, or the first few words, which didn't grab attention. - 2How many bought or asked something
Of the people who opened it, how many wrote back, booked, or bought something within the next forty-eight hours. This is the number that pays the bills, and the only one really worth comparing from one broadcast to the next. - 3Who still hasn't written back
Of the people who'd gone quiet for months before the broadcast, how many are still quiet afterward. That group doesn't need another message just like the last one: it needs to come off the main list, or move to a separate list for people who no longer buy.
The first two drop off like a funnel: more people always open it than end up buying or asking. The third one stands apart: it counts the people who are still quiet and tells you who shouldn't get the same message again. Where the funnel narrows, more than any single number, is what tells you where the problem is.
Here's an example of how this might look for a small business: out of every ten people who get the message, six open it, a little over one buys or asks a question, and two still don't show any signs of life even though they read it.
What to change based on what you see
With these three numbers, you already know what to tweak next time, but only one thing. If you change the text, the price, and the list all at once, and the next broadcast does better, you won't know which of the three fixed it, and you'll keep guessing instead of deciding.
The clue is in which of the two numbers falls short: whether people open it but don't buy, or whether they don't even open it.
- The message got read, so the problem isn't when you sent it
- The offer didn't land, or wasn't clear in the first few lines
- It didn't say what to do next: reply, book, or order
- The problem isn't the text, because nobody actually read it
- The day or time doesn't match when those people check their phone
- The sender isn't easy to recognize at a glance among their chats
Which one to pick: If people opened it and didn't buy, change the offer or the closing line that tells them what to do, not the timing. If they didn't open it, change the day or time before you touch a single word of the text.
That wraps up what you need to send a broadcast with less risk of getting blocked and without sending it blind: who not to message, how many lists to split your contacts into, how often to send it, what reads well in three seconds, and now, what to check the next day so you don't repeat the same mistake next month.
- You know exactly what to check the day after every broadcast: who opened it, who bought, and who's still quiet
- You know that opening and buying drop off like a funnel, and that where it narrows is the clue to what's not working
- In your next broadcast, you change just one thing, not the text, the price, and the list all at once
- You can tell whether the problem is in the opening line and send time, or in the offer and the message's closing line
