How to plan a marketing campaign (that a small business can actually run)
By Ly Viet VuUpdated 24 Oct 2026
The short answer
To plan a marketing campaign, start with four things: one sentence your customer can say back to you, one moment from their real life, one belief you want to flip, and one first step so small they'd be silly not to take it. Then steal a play that already worked for a big brand, decide what AI can run and what needs you, and test it small before you spend real money. A campaign is one clear idea made easy to join. It is not a big budget.
The flip
Most owners think a campaign needs an agency, a big budget and a long deck. The campaigns I remember from twenty years in this game were one clear idea that people could feel, touch or play with. You can plan that at your kitchen table.
The plan, step by step
- Say it in one sentence. If your customer can't say it back in one breath, you lost 'em. Write the idea so a 12-year-old gets it. Cut everything else.
- Find the customer moment. Not your product. Their life. The minute before they need you. The moment they're annoyed, hungry, tired or proud. Show them that, and they lean in.
- Pick the belief to flip. What does your customer believe before, and what should they believe after? "Healthy food is boring" becomes "healthy food is the fun part of my day." One flip per campaign.
- Make the first step small. A free taste. A two-minute quiz. A WhatsApp message (or Zalo, in Vietnam). Big asks feel risky. Small asks feel safe.
- Steal a play and make the call. Find a famous campaign that pulled the same flip. Then sort the work into three lines. 1st line: AI can run it. 2nd line: AI plus you. 3rd line: needs a pro, and you know exactly which part.
- Decide what counts before you start. Count the people who act, not the people who clicked once. Visits, messages, bookings, sales. Pick one number before launch, then test small for two weeks and look at it.
From my own tape
I co-founded an agency in Saigon (Ho Chi Minh City) in 2007 and later ran Wunderman Thompson Vietnam as CEO. Here's what our team's best work taught me, in plain words.
- Make the claim something people feel. Tea+ promised "body light, feel light." Hard to show, harder to believe. So the team built a sealed box in a Ho Chi Minh City mall, screens on every wall and the floor. You took a sip, a sensor caught it, and drone footage made you fly over the city. Don't tell people it feels light. Make them fly.
- Turn your proof into an object. Reading what moms posted online showed they didn't know baby skin takes 12 months to develop. So Babi Mild made a book whose pages matched skin thickness from month 1 to month 12. A fact became something you could hold.
- Make it a game, then do the boring work. For Pepsi's Beyonce campaign, the team rebuilt an old vending machine with a big touchscreen and a motion sensor. You danced the routine to win a Pepsi. The idea was the fun part. What kept it running was a boring rule: every part logged what it did, and when something broke, you checked the input first.
- In a crisis, change the box, not the skills. In April 2020, when the world stopped, my production team became an online production service in about two weeks: livestreams, online launches, small crews. Same people, new menu.
You don't need a mall or a sensor. You need the same habit: one idea people can feel, and a first step that's easy to take.
Your rink: a café, this week
Say you run a café. Your one sentence: "The best ten minutes of your morning." Your customer moment: the rushed commuter who drinks bad coffee at the desk. Your flip: "good coffee takes too long" becomes "good coffee takes four minutes here." Your first small step: order ahead on WhatsApp and skip the line. Your play: steal Heineken's WhatsApp bot. Theirs traded a long voice note for a free beer. Yours trades a first pre-order for something small, like a free pastry. 1st line: AI writes the posts and answers the WhatsApp orders. 2nd line: you pick the photo and the offer. 3rd line: nobody. Your number: WhatsApp pre-orders in two weeks.
Plays you can steal today
Each play breaks down a famous campaign and makes the call on what AI can run for you:
- Heineken: Could Have Been a Heineken1st line: AI can run it
- Columbia Sportswear: Expedition Impossible1st line: AI can run it
- KFC Vietnam: Xin Miếng (Gimme a Bite)2nd line: AI plus you
Every play has a free play card. Download it, upload it to your AI and paste the prompt on page 2.
A campaign isn't a budget. It's one idea people can feel and one step so easy they take it. Steal the play. Run it.
Questions owners ask
Do I need a big budget to run a marketing campaign?
No. Start with one clear idea and one small first step, and test it for two weeks before you spend more. Many of my plays are 1st line: AI tools can run most of the work for a small monthly cost.
Can AI plan my marketing campaign?
AI can draft the plan, write the posts and answer messages. You still make the calls: the idea, the offer and what counts as a win. On every play I say which work AI can run and which stays with you.
What is the first step in planning a campaign?
Write your idea in one sentence your customer could say back to you. If you can't, the rest of the plan won't save it.
Do you plan marketing campaigns for businesses?
Yes. I plan marketing campaigns for owners, in person in Ho Chi Minh City and Vancouver, or online. Or start free: email letstalk@lyvietvu.com with what you sell and who buys it, and I'll pick your first play.
