If you run an online store and are looking for a channel that truly delivers, it’s time to get acquainted with WhatsApp. It’s not just a messenger – it’s your new sales tool.
Why? Because it combines everything you need: speed, convenience, personalization, and – most importantly – outstanding results.
✅ 1:1 conversations that build trust
✅ Multimedia support (images, CTA buttons)
✅ Ability to continue conversations even after closing the browser
In a world where customers expect instant responses, this is an advantage you simply can’t ignore.
The Data Speaks for Itself
Customer data collected by edrone (September 2025) clearly shows: WhatsApp outperforms other communication channels in eCommerce.
Comparison Table
Channel | Abandoned Cart Conversion | Newsletter Conversion | Revenue per Message (R$) |
2.2% | 1.0% | 4.87 | |
SMS | 0.9% | 0.3% | 1.38 |
0.03% | 0.04% | 0.15 |
➡️ WhatsApp generates over 3x more revenue than SMS and as much as 32x more than email.
Click-through Rate – Customer Engagement
CTR (Click-through rate) shows how many customers actually click links and react to messages. It’s the best indicator of engagement:
Channel | CTR |
25.06% | |
SMS | 12% |
0.5% |
➡️ WhatsApp engages over 2x better than SMS and 50x better than email.
CTR on WhatsApp reaches an impressive 25.06% because it’s real-time communication. The customer receives a message in the app they use daily – and reacts instantly. It’s not just another marketing campaign that gets lost in an inbox, but a personalized conversation in a natural environment.
WhatsApp messages feel like 1:1 interactions: short, precise, enriched with images, links, or CTA buttons. More importantly – customers feel understood, as if the brand is addressing their exact needs. This makes messages far more clickable and engagement significantly higher than in other channels.
Additionally, automation allows brands to send real-time notifications, promotion reminders, and smart follow-ups. This boosts the chances of instant clicks and actions. Such communication builds trust – customers don’t feel like the target of mass advertising but like real conversation partners.
How Much Can WhatsApp Really Deliver?
📌 Example 1: Abandoned Cart
100 messages per day → 2.2% conversion = 2.2 orders.
Average cart: R$250 → R$16,500 monthly revenue.
📌 Example 2: Promotional Campaign
5,000 messages → 1.0% conversion = 50 orders.
Average cart: R$250 → R$12,500 revenue from one campaign.
(For comparison: email would generate just 2 orders = R$500).
📌 Example 3: Customer Reactivation
1,000 inactive customers → 1% conversion = 10 orders.
Average cart: R$250 → R$2,500 revenue.
Monthly Summary
Scenario | Monthly Revenue |
Abandoned carts | R$16,500 |
2 promotional campaigns (2 × 5k) | R$25,000 |
Customer reactivation (1×/month) | R$2,500 |
Total | R$44,000+ |
And these are just a few examples. The potential of WhatsApp goes far beyond – and with edrone you gain the tools to fully unlock it.
The Global Potential of WhatsApp
🌍 2 billion users worldwide
📞 175 million people contact businesses daily
📦 54% of customers want to receive order updates via WhatsApp
💬 39% use it for customer service

When Should You Use WhatsApp in eCommerce?
WhatsApp is more than just a messenger – it’s a customer service, sales, and marketing hub all in one. The key question is: when is the right time to use it?
🔄 1. When customers abandon their carts or haven’t purchased in a while
Perfect for reactivation – the message looks like a casual conversation, not pushy marketing.
👉 Example:
“Hi! Your cart is still waiting. Should we save something for you?”
– this type of message can generate up to 2.2% conversion, i.e. 22 orders for every 1,000 messages.
🛍️ 2. When running promotional campaigns
Send personalized messages with an image, link, product description, PDF, and CTA – everything you need for effective sales in one message.
🔔 3. When customers are waiting for updates
Order statuses, promotions, new arrivals – instead of leaving customers uncertain:
notify them about sales,
showcase a new collection.
📈 As many as 54% of customers prefer to receive this information via WhatsApp.
🙋♂️ 4. When customers need support
WhatsApp is the most convenient customer service channel:
fast response times,
ability to continue the conversation after closing the app,
less formal, more human contact.
🔁 It replaces long phone calls and emails, which often end in frustration.
💬 5. When personalization matters
WhatsApp allows you to:
communicate in the customer’s language,
use CRM data for segmentation,
send precise product recommendations.
As a result, every message feels personal – not like just another mass campaign.
WhatsApp vs. Other Channels
✉️ Email – best for longer content and catalogs.
📲 SMS – ideal for short, urgent notifications.
💬 WhatsApp – highest effectiveness, greatest revenue, and widest application.

👉 The data doesn’t lie: WhatsApp generates the highest revenue in eCommerce.
WhatsApp – Cost vs. Revenue
In Brazil (prices vary by country, according to Meta’s pricing), the cost per WhatsApp message is:
Message Volume | Price per Message (R$) |
0–1000 | 0.42 |
1000–10,000 | 0.41 |
10,000+ | 0.40 |
💡 Average revenue per WhatsApp message = R$4.87.
Cost per message = R$0.40–0.42.
ROI = almost 12x return per message.
👉 In other words: every R$1 invested in WhatsApp generates nearly R$12 in revenue.
Why Does This Matter?
Unlike SMS or email, where revenue per message is much lower (several times for SMS, dozens of times for email), WhatsApp ensures:
the best cost-to-performance ratio,
scalability – the more messages you send, the lower the unit cost,
predictable results – you can easily calculate the extra revenue from any given campaign.
Conclusion
WhatsApp is the channel that delivers unmatched results in eCommerce – from a CTR of 25.06%, through average revenue of R$4.87 per message, to an impressive ROI of nearly 12x.
It’s not just another marketing channel, but real-time, personalized 1:1 communication that builds relationships, increases loyalty, and directly drives sales.
