South African businesses have two powerful direct marketing channels available to them — email marketing and WhatsApp marketing. But which one should your business be using? And which one delivers better results in the South African market?
In this article I’ll compare both channels head to head so you can make the right decision for your business.
THE STATE OF DIGITAL COMMUNICATION IN SOUTH AFRICA
Before we dive into the comparison it’s important to understand the South African digital landscape.
South Africa has over 25 million active internet users. WhatsApp is by far the most popular messaging app in the country with over 14 million active users. Email is also widely used especially in the business and professional sector.
Both channels have their place in a well-rounded digital marketing strategy — but they work very differently and suit different types of businesses and goals.
WHAT IS EMAIL MARKETING?
Email marketing is the practice of sending commercial messages to a list of people who have opted in to receive communications from your business.
It typically includes:
- Newsletters
- Promotional campaigns
- Product announcements
- Automated welcome sequences
- Abandoned cart reminders
- Customer retention campaigns
Email marketing is one of the oldest forms of digital marketing but remains one of the most effective. Studies consistently show that email delivers an average return of R42 for every R1 spent — making it the highest ROI digital marketing channel available.
WHAT IS WHATSAPP MARKETING?
WhatsApp marketing involves using WhatsApp to communicate with customers and prospects directly on their phones.
It can include:
- Promotional messages
- Order confirmations and updates
- Customer support conversations
- Appointment reminders
- Exclusive offers and deals
- Product catalogues
WhatsApp marketing has exploded in popularity in South Africa because of how deeply embedded WhatsApp is in South African culture. Unlike many other countries where WhatsApp is just one of many messaging apps South Africans use it for virtually everything — personal conversations, business communication, community groups and more.
EMAIL MARKETING VS WHATSAPP MARKETING — THE COMPARISON
OPEN RATES
This is where WhatsApp wins hands down.
Email open rates in South Africa average around 20-25%. This means that for every 100 emails you send only 20-25 people actually open them.
WhatsApp messages have an open rate of over 90%. Almost everyone who receives a WhatsApp message reads it — usually within minutes of receiving it.
Winner: WhatsApp ✅
REACH AND LIST BUILDING
Building an email list is generally easier than building a WhatsApp contact list.
With email you can collect addresses through your website contact form, newsletter signup, lead magnets and social media. Most people are comfortable sharing their email address.
With WhatsApp you need people’s phone numbers — which feels more personal and private. Many people are reluctant to give their phone number to businesses.
Winner: Email ✅
CONTENT FLEXIBILITY
Email wins easily here.
With email you can send long-form content with images, videos, multiple links, formatted text, headers and HTML design. You have complete control over how your message looks.
WhatsApp messages are limited to text, images, documents and short videos. You can’t create the same polished branded experience that email allows.
Winner: Email ✅
PERSONALISATION
Both channels allow personalisation but email marketing tools make it much easier at scale.
Email platforms like Mailchimp and ActiveCampaign allow you to personalise every email with the recipient’s name, purchase history, location and behaviour. You can segment your list and send highly targeted campaigns to specific groups.
WhatsApp personalisation requires more manual effort unless you’re using the WhatsApp Business API with an automation tool.
Winner: Email ✅
DELIVERABILITY
WhatsApp messages are delivered directly to the recipient’s phone — there’s no spam folder, no promotions tab and no deliverability issues.
Email on the other hand often ends up in spam or promotions folders. Even legitimate emails from reputable senders sometimes get filtered — reducing your actual reach.
Winner: WhatsApp ✅
RESPONSE RATES
WhatsApp generates significantly higher response rates than email.
When you send a WhatsApp message people often reply conversationally — making it an excellent channel for customer service, appointment bookings and sales conversations.
Email responses are typically lower and more formal. People often read emails without replying even if they’re interested.
Winner: WhatsApp ✅
COST
Email marketing is extremely cost effective at scale. Platforms like Mailchimp offer free plans for up to 500 subscribers and paid plans start from as little as R150 per month for thousands of contacts.
WhatsApp Business is free for basic use. However for larger businesses that need automation and bulk messaging the WhatsApp Business API can be expensive — typically costing R0.50 to R1.00 per message sent.
Winner: Email ✅ for scale, WhatsApp ✅ for small businesses
AUTOMATION
Email marketing automation is incredibly powerful and well-established.
You can set up automated sequences that send the right message to the right person at exactly the right time — welcome sequences, birthday emails, re-engagement campaigns, abandoned cart reminders and much more.
WhatsApp automation is possible but more complex. You need to use the WhatsApp Business API with a third-party platform like Twilio or MessageBird — which adds cost and technical complexity.
Winner: Email ✅
CUSTOMER TRUST AND PRIVACY
Many South Africans feel that WhatsApp messages from businesses are intrusive — especially if they didn’t specifically opt in to receive them.
Email has been used for business communication for decades and most people expect to receive promotional emails from businesses they’ve interacted with.
Always make sure you have explicit permission before sending marketing messages on either channel.
Winner: Email ✅ for trust
WHICH SHOULD YOUR SOUTH AFRICAN BUSINESS USE?
The honest answer is both — but for different purposes.
USE EMAIL MARKETING FOR:
- Newsletters and regular updates
- Promotional campaigns and sales
- Long-form content like case studies and guides
- Automated customer journeys
- Re-engaging inactive customers
- Professional B2B communication
USE WHATSAPP MARKETING FOR:
- Appointment reminders and confirmations
- Order updates and delivery notifications
- Customer service and support
- Exclusive flash sales and urgent offers
- Personal follow-ups after meetings
- Local community building
THE IDEAL STRATEGY FOR SOUTH AFRICAN BUSINESSES
The most effective approach is to use both channels together in a complementary way.
For example:
- Send a promotional email announcing a special offer
- Follow up with a WhatsApp message 24 hours later for people who didn’t open the email
- Use WhatsApp for personal follow-ups with hot leads
- Use email for nurturing colder leads over time
This combined approach maximises your reach and ensures you’re communicating with customers on their preferred channel.
