Sales compared with the blast cost only, without ad spend. Every business is different. This isn't a promise.

Sound familiar?

You paid good money for every customer.
Then sold to them once and went quiet.

Every name on your list cost you an ad or a marketplace fee. Most businesses sell to that person once. Then they pay again to find someone new.

Meanwhile, thousands of people who already trust you sit in a spreadsheet or a phone. They hear nothing from you.

And when you finally send a blast, it goes wrong in ways nobody warned you about.

  • 01

    The ads keep costing more

    Each new customer costs more than last year. Your profit gets thinner.

  • 02

    You blasted once, and nothing sold

    Lots of people read it. Hardly anyone ordered. So you decided blasting doesn't work.

  • 03

    You're scared of losing your number

    One wrong blast from a normal WhatsApp number can get it banned. Every chat on it, gone.

  • 04

    You don't know where to start

    Which customers? What offer? How many messages? Which day? Nobody has shown you the steps.

Drawings, not real figures.

Every one of these can be fixed. The key is doing things in the right order. This book shows you that order.

Why now

One sale costs you
more every year

Ad costs and marketplace fees keep creeping up. Even WhatsApp now charges for replies. The one thing you fully own is your list of past buyers.

  • RM45–160

    what one sale from Facebook ads costs Malaysian online stores

  • +8%

    service tax on every ringgit of Meta ads, since March 2024

  • 20–30%

    of every Shopee and TikTok Shop sale goes to fees and commission

  • 6–7 sen

    for each WhatsApp reply since 1 October 2026, after 1,000 free a month

Example drawings. The receipt shows the 8% on an example RM1,000 of ads.

Now compare. When you sell to your own list, one order costs only the messages it takes to get it:

What one order costsYour database at the market rate of RM0.38 a message.
  • A new customer, from Facebook ads (Malaysian online stores)RM45–160
  • Your database, a strong offer (1 order in every 50 messages)RM19
  • Your database, a normal promo (1 in 100)RM38

No ad to pay for. Just the messages. Plan it well, and it's the cheapest launch you'll run all year.

Sources: Facebook ad costs in Malaysia, one agency's sample of 500+ SME accounts, 2024–2026. Service tax on digital services by foreign providers raised from 6% to 8% from 1 March 2024 (Royal Malaysian Customs). Marketplace fees of 20–30% of each sale: commission, transaction and service fees together on Shopee and TikTok Shop, Preda's estimate. WhatsApp's service-message charge from Meta's rate card of 1 October 2026; the cost depends on your provider and the exchange rate.

The difference

Same list, same product.
A very different launch.

The same launch, day by day

How most businesses blast

Nothing for 14 daysOne blast, with a discount

What the RM100k launches did

Wake the listSneak peekReminderLaunchRelaunch
14 days beforeLaunch day

How most businesses blast

  • One message to everyone, on launch day, with a discount
  • Sent from the phone the team uses for orders
  • Replies answered one by one, no proper page to buy from
  • No record of who bought, so buyers get the same reminder again

A colder list

Lots of reads, few orders. And customers who start to ignore you.

What the RM100k launches did

  • Woke the list up 12 to 14 days before selling anything
  • Sent from official WhatsApp, on their own number
  • Added bonuses before they cut the price
  • Sent buyers to a sales page. 70–80% of sales came from there
  • Stopped reminding people who'd bought, and followed up on a plan

RM8–12

in sales for every RM1 spent on blasting.

RM300k+

From chapter 1
A health supplement brand. 34,000 past buyers. 3 blasts. Over RM300k in sales, with a little ad retargeting alongside. The blasts cost about RM38,760 at the market rate. That's sales of about 7.7 times the blast cost.

About us

We send the blasts.
We see what sells.

Preda Agency sends official WhatsApp blasts for Malaysian businesses. On every launch, we watch who reads, who replies, who buys and who blocks.

Our clients run their own launches. But we see all of them side by side. And the ones that made RM100k+ kept doing the same things.

So we wrote those things down. Most owners learn them the hard way, one wasted blast at a time. We'd rather you got it right first time.

One blast, and what comes back

Clients trust us with their customers, so we name none of them. Figures are rounded, and the example messages were written for the book.

Questions

Before
you decide

My list is small. Is it still worth it?

Yes. The steps are the same for 2,000 customers or 200,000. Only the numbers change. Put your list size into chapter 1's calculator, and see what it can earn before you spend a sen.

Do I need official WhatsApp already?

No. Chapter 4 explains what it is (the WhatsApp Business Platform) and how to get it. It also shows how it differs from the WhatsApp Business app on your phone. Read the whole book first, then sign up.

Is it only about WhatsApp?

Mostly, because that's where your customers read. But it also covers email, SMS, WhatsApp channels and communities, and when each one is cheaper.

Will it work for my business?

If you sell to customers and have past buyers, yes, in Malaysia or any country with WhatsApp. It's about your customers and your offer, so it works across products. Prices are in ringgit, but the maths works in any currency. Chapter 2 helps you check your product is ready for a blast.

Is it a PDF?

No. You read it in your browser, on phone or computer, after signing in with your email. That's what lets the tools work and save your answers.

How long do I keep access?

For life. Pay once, no subscription. Your answers stay saved, and future updates to the book are yours too.

Do you run the launch for me?

No. The book teaches you to run it yourself. If your list has 30,000 contacts or more and you want a lower blasting cost, you can apply to work with us: we send the blasts on your own number.

What if it's not for me?

Email us within 7 days of buying and we'll refund you in full. Your access closes when the refund goes through.

Disclaimer and terms of this offer

Please read this in full. By buying Behind the Blast you confirm you have read, understood and accepted it, together with our Terms & Conditions. Last updated 5 October 2026.

1. General information only. Behind the Blast and this page are for general information and education. Nothing in them is legal, financial, tax, accounting, data protection or other professional advice, and reading them does not make us your adviser. Get advice from a qualified professional about your own business before you act on anything in the book.

2. No guarantee of results. The launches, figures and returns we describe, including the 18 launches, RM8–12 in sales for every RM1 spent on blasting, and the RM300k+ launch, are what particular businesses achieved with their own products, offers, customer lists, timing and teams. They are not typical, they are not a promise, and they are not a prediction of what you will achieve. Many people who buy a business book get little or no result from it. Your results depend on your product, your customers, your offer, the work you put in, and things outside anyone's control. We do not guarantee that you will make any sales or earn any money.

3. Calculators and estimates. The calculators, order rates, costs and worked examples in the book are planning guides built on stated assumptions. They are not forecasts. Real delivery, read, reply and order rates, and real costs, will differ.

4. Your messages are your responsibility. You alone are responsible for every message you send, and for how you collect, keep and use your customers' personal data. That includes getting the consent the law requires, honouring every opt-out, and following the Personal Data Protection Act 2010 (or the data protection law where you and your customers are), the Communications and Multimedia Act 1998, consumer protection and price rules, and WhatsApp's Business Messaging and Commerce Policies. Meta and other platforms can limit, restrict or ban a number, a template or an account at their own discretion. We are not responsible for any action a platform takes against you, or for any fine, claim or complaint that follows from what you send.

5. Platforms, prices and rules change. WhatsApp, Meta, marketplaces, payment providers and email platforms change their prices, limits, features and rules, often without notice. Every price and fee on this page and in the book is as published or reported on the day we checked it, depends on your provider and the exchange rate, and may be out of date by the time you read it. Check current terms with each provider before you rely on them.

6. Other companies' tools. The book mentions tools and services run by other companies. We do not control them and are not responsible for their products, prices, availability or conduct.

7. Client privacy and examples. No client is named. Industries are described broadly, and figures are rounded or given as ranges. The brands, people, messages, pages and pictures in the examples were made up or generated for the book; any likeness to a real business or person is a coincidence.

8. Not connected with Meta or other platforms. WhatsApp, Facebook and Meta are trademarks of Meta Platforms, Inc. Shopee, TikTok Shop, Stripe and the other names mentioned belong to their owners. Preda Agency is not affiliated with, sponsored by or endorsed by any of them.

9. The money-back guarantee. Ask for a refund by email within 7 days of the day you bought, from the email address you bought with, and we will refund the full price to the original payment method. Your access ends when the refund is made. The guarantee is one refund per person.

10. Your licence to use the book. Buying gives you a personal licence to read the book and use its ideas in your own business. It is for the email address that bought it. Lifetime access means for as long as we offer the book online. You may not share your sign-in, copy, record, resell, republish or hand the content to another person or to software. We may suspend access that is shared or misused, without a refund.

11. Limit of our liability. As far as the law allows, Preda Agency Sdn. Bhd. and its directors, staff and partners are not liable for any loss or damage arising from your use of the book, this page or anything in them, whether direct or indirect, including lost sales or profits, lost data, a restricted or banned number, or any fine or claim. Where our liability cannot be excluded, it is limited to the amount you paid for the book. Nothing here takes away a right you have under the Consumer Protection Act 1999 or any other law that cannot be taken away by agreement.

12. Accuracy and updates. We work to keep the book accurate as of the date it was written, but it may contain mistakes. We may update, correct or remove any part of it, or of this page, at any time.

13. Law and who we are. This offer is governed by the laws of Malaysia, and the courts of Malaysia decide any dispute. The seller is Preda Agency Sdn. Bhd. (202601014225). Questions: hi@preda.agency.
