10 Expert Tips for Writing Effective WhatsApp Marketing Messages

If you receive a WhatsApp notification, you open it instantly, whether it’s important or not. With over 2.5 billion+ users and 100 billion+ messages sent daily, WhatsApp has become the world’s most active communication channel, and brands are using it more than ever to engage customers. That’s why integrating WhatsApp into your marketing is a smart way to drive traffic, enhance loyalty, and stay top-of-mind.

But here’s the catch: your customers are already flooded with the same offers, same templates, same automation, and the same predictable messages from other brands. So where do you stand out? The answer is simple: your message. A powerful WhatsApp marketing message can not only attract your customer but also recover abandoned carts, re-engage inactive users, and bring in new shoppers every single day, if crafted with emotion, relevance, and intent.

To help you create those high-converting, heart-connecting messages, we created this blog. You’ll find real examples, industry-backed insights, and practical strategies grounded in the current market landscape. 

Top 10 Tips for Writing Promotional WhatsApp Messages for Higher Conversions

Whether you are launching a new product, running an exclusive sale, or offering a discount, it’s important to make it relevant, targeted, and, most importantly, emotionally connected to the user to drive results. So, to get started, this guide provides a clear explanation to help you understand.

1.  Focus on a Strong Welcome Message

You’ve probably heard the saying “first impression is the last impression,” and it truly applies here. A warm, professional welcome and a WhatsApp marketing message instantly build trust and set the right tone for new subscribers. When customers feel valued from the start, they’re more likely to stay engaged and explore your products.

Simple Welcome Message Example:

“Welcome, Suraj! We’re happy to have you here. Enjoy a special 30% welcome offer on any product. Use code WLCM30 and shop now!” A message like this feels personal, clear, and encouraging, perfect for turning new subscribers into active customers.

Impact of a Strong Welcome Message

• Welcome messages on WhatsApp often achieve 30–40% CTR, significantly higher than email, resulting in better ROI.
• On average, 1 in 3 new customers interacts within the first 5 minutes of receiving a welcome message.
• Personalized welcome offers can boost purchase intent and increase first-order conversions.

2. Create Interest-Based Segments

‍
Sending sports car offers to someone who doesn’t drive or promoting lipstick shades to a man who has no interest in makeup will never bring results. Not everyone has the same taste, preferences, age group, or buying intent, so one message for all simply doesn’t work. That’s where intelligent segmentation comes in. It allows you to segment your audience by gender, age, location, shopping behavior, browsing patterns, and interests.

Example of a Segmented Message:

If someone frequently checks skincare products, a tailored message like this performs far better:

“Hey Aditi! We curated new ethnic wear styles we think you’ll love. Enjoy an exclusive ₹250 off with code ETHNIC250.” Personalized, interest-based recommendations feel relevant and instantly grab attention.

Impact of Smart Segmentation

• Sending relevant content can reduce opt-out rates by 15–20% on average.
• When customers feel the message is relevant, up to 80 out of 100 people open the link, a massive uplift in engagement.
  

3. Abandoned cart Alert 

When someone leaves a product in their cart, it usually means they want it but couldn’t purchase it, perhaps due to budget constraints, being busy, or planning to buy later. Gently reminding them through promotional WhatsApp messages can encourage purchase.

Example to write an abandoned cart message:

You can send something like: “Hey Manisha, we noticed you left the Pink Tumbler in your cart. Complete your purchase now with 40% off and keep your body hydrated.” It’s personal, caring, and practical, precisely the kind of nudge that encourages customers to finish their purchase.

‍
Impact of abandoned cart message

• Personalized abandoned cart recovery messages help brands recover 25–40% of lost sales, directly boosting revenue and ROI.
• Almost 1 in 4 shoppers leave products in their cart, so sending a tailored WhatsApp reminder within 24 hours significantly increases the chances of recovery.

4. Personalized Recommended Messages

‍
Personalization goes beyond just using a customer’s name. It’s about knowing what your customer really wants and showing it to them. Use their location, interests, recent searches, or purchases to make the message feel connected. With the latest AI chatbots, you can also suggest color combinations, sizes, or other relevant product details.

Personalized message examples;

Suppose someone is browsing a pink T-shirt: “Hey, Sameer, your favorite pink T-shirts are back in stock! Get 30% off and complete your purchase today. Also, check which size fits you best.” This approach encourages repeat purchases, making customers feel valued and understood.

Impact of Personalized Recommendations

• Increases repeat purchases by 10–20%, as customers receive suggestions aligned with their actual interests.
• Improves conversion rates by 8–12%, especially when size, color, or style recommendations are included.

5. Quick Action with Urgent Offers

The truth is, competitors are everywhere. If you don’t offer the right deal at the right time, customers will switch brands. Creating urgency around your products is key to boosting revenue and driving faster purchases.

‍
Example to Create an Urgent Offer Message

If you know a customer is considering a purchase, give them a compelling offer through a promotional WhatsApp message. For example: “Winter Sale is here! Grab your perfect office outfit with mega discounts. Buy two items worth ₹3000 and get ₹1000 off.” Even if they weren’t planning to buy, this message creates urgency, makes them reconsider, and encourages them to complete the purchase with you.

Impact of Offer Messages

• Time-sensitive discounts can reduce decision-making time by nearly 50% helping customers check out faster.
• Brands leveraging FOMO through urgency triggers often see up to a 30% increase in average order value, as customers add more items to avoid missing out on the offer.

6. Use Visuals & Audio to Capture Attention

‍
Recently, using emojis, GIFs, and fun visual elements has become a strong trend. There’s a huge amount of meme-style content online, and when brands use it correctly, it doesn’t just capture attention it creates a genuine emotional connection. Adding GIFs, videos, voice notes, and emojis makes your WhatsApp marketing messages feel lively, human, and relatable.

Example of Using Visuals

“We need to talk about your commitment issues… 😞

Hey Riya, we saw you eyeing the shoes 👟 and then… nothing! Finish your purchase now and get 30% off from us! We’re here to help you make it official. 💍” A message like this is humorous, visual, and expressive, making customers smile while nudging them toward completing the purchase.

Impact of Visualized Messages

• Adding visuals or GIFs can boost recall by around 30%, as customers find the content more engaging and easier to consume.
• Brands using product videos often generate up to 50% CTR, especially for demos, try-ons, and unboxing content that helps customers picture the product better.‍

7. Case Studies: Real Brands Crushing It with WhatsApp

‍
Mouth-to-mouth communication is a timeless marketing driver that shapes both customer preferences and final buying decisions. On WhatsApp, this influence becomes even stronger because people consume content in a personal, trusted space. Sharing real testimonials or short case studies directly on promotional WhatsApp messages builds instant credibility, reduces hesitation, and helps customers feel confident about choosing your brand.

Sample WhatsApp message to showcase a customer case study:

“Hey Rahul! Here’s a quick demo of the new Noise-Cancelling Earbuds 🎧 you viewed yesterday.

Watch how they block 90% background noise 👉 [Demo Video Link]

Buy today and get an extra 15% off. Limited time only!”

Impact of Testimonial Messages on WhatsApp

• 83% of consumers trust recommendations from people they know, and 66% trust online reviews or customer opinions, showing how testimonial-based WhatsApp messages naturally boost trust and ROI. 
• 78% of B2B buyers use case studies when researching purchases, proving that real examples significantly improve conversion rates. 

8. Turn Feedback Into Conversations

Interacting with customers helps any brand grow, but sending only sales-driven messages can slowly reduce their interest. Customers actually want to be part of your brand’s improvement journey. Asking for feedback not only shows you value their opinion but also helps you understand what they like, what confuses them, and what needs fixing. This makes their future experience smoother and your messages far more effective.

Example of a WhatsApp Feedback Message:

“Hi Rahul! We’d love your quick feedback ❤️

How was your experience with us today?

a) Loved it

b) It was okay

c) Needs improvement

Your response helps us improve and serve you better!”

‍
Impact of Feedback Collection:

• Brands that regularly ask for feedback see up to a 43% increase in customer retention.
• Collecting feedback can increase customer satisfaction scores by 25%, since customers feel heard.

9. Make Your CTA Unmissable

‍
CTA stands for Call to Action, and it’s the part of your WhatsApp message that clearly tells customers what to do next. A CTA highlights what the brand offers and how it adds value to the customer’s life, whether it’s saving money, addressing a need, or helping them make quicker decisions. You may already know the writing style and tone that fit your brand, but it's how you end the message that truly drives action. A strong CTA can turn a casual reader into a paying customer.

Examples of High-Impact CTAs That Push Customers to Act:

• “Grab It Before Midnight!”
• “Limited Stock—Buy Now”
• “Last 2 Hours to Save”
• “Talk to Our Experts”
• “Book Your Slot Instantly”
• “Claim Your Offer Today”
• “Check Your Best Price Now”

These CTAs can be further personalized based on customer behaviour, interests, browsing history, or purchase intent.

Impact of Strong CTAs

• Personalized CTAs deliver 202% higher conversion rates than generic ones, showing how much the “right ending” of a message can influence revenue.
• Increasing the size or visibility of a CTA button can boost click-through rates by up to 90%, demonstrating that customers respond better when the next step is easy and obvious.
  
  

10. Refine Your Copy with Continuous Testing

Sending a message to your customers isn’t the final step; what truly matters is tracking how they respond. Understanding what your audience actually likes is equally important. With A/B testing, you can compare two similar WhatsApp campaigns to see which one performs better and gather valuable feedback for improving future messages.

Example to understand and refine your copy:

Suppose you’re running two WhatsApp campaigns with the same offer:

1. Version A – Humorous Tone: “Your cart is crying. 🛒💔 Save it before it’s gone—grab your favourites now!”
2. Version B – Simple Informative Tone: “Reminder: You still have items waiting in your cart. Complete your purchase now.”

After sending both, Version A gets more opens and clicks, while Version B receives lower engagement. This shows that your audience connects better with a fun, conversational tone. So running more simple, flat messages won’t help; they’ll only waste your budget and reduce your campaign impact.

Real Impacts of Testing 

• A/B testing can increase conversion rates by 49% when brands optimize their messaging based on customer behavior.
• Personalized variants tested through A/B experiments generate 20%+ more clicks, significantly boosting message performance.
