Digital media communication has evolved.In 2025, companies face a crucial decision: WhatsApp vs Email – which channel delivers better results?We at Chatarmin, your partner for WhatsApp marketing, are convinced that the direct line to the customer makes all the difference. While email marketing has been a staple in marketing for decades, instant messaging services like WhatsApp are revolutionizing how businesses communicate with their customers.

But what really distinguishes the two channels? It’s not just about open rates, spam filters, or technical functionality. It’s about proximity, speed, and relevance. In a world where people expect instant information, the channel that meets those expectations wins. WhatsApp scores with end-to-end encryption, personal messages, and an app almost everyone has on their phone. Emails, on the other hand, offer structure, are familiar, and often still the standard in the B2B sector.

Our goal is to give you the ultimate comparison so you can decide which marketing channel is right for your business. Whether WhatsApp newsletter or email newsletter – we examine all the differences and similarities.

Introduction to modern customer communication

The world of marketing is changing rapidly. In the past, a simple email address was enough to reach customers. Today, you need more. People communicate faster, more spontaneously – often via messenger. Companies that still rely solely on email marketing are missing out on valuable opportunities.

WhatsApp has become firmly established as a messenger service. Its functionality is extensive: personal chats, images, videos, GIFs, quick replies – all in one app. No wonder WhatsApp messages are so well received. They don’t end up in spam folders but land directly in the customer’s chat. This builds trust, proximity, and high open rates.

Of course, traditional email also has its strengths. It offers plenty of space for detailed content, is well-suited for design, and perfect for longer marketing campaigns. But relying solely on email risks being overlooked by modern customers. The solution? Supplement, not replace. Use both channels strategically – depending on your audience and objective.

WhatsApp Marketing vs Email Marketing – An Overview

Email marketing has existed since the 1990s. Companies send newsletters, offers, and information to their email lists. It’s a proven way to build customer loyalty. But by 2025, much has changed. Open rates are dropping, spam is a problem, and many recipients don’t read newsletters anymore.

Still, email remains a key channel. It’s platform-independent, everyone has an address, and for many people, daily email use is the norm. Especially in the B2B sector, email marketing has persisted because it looks professional and integrates well into existing systems.

The big advantage? You can share detailed information, send attachments, and design highly customized messages. But the challenge remains: getting attention. That’s where WhatsApp comes in – where messages are more personal, direct, and often more impactful.

What is WhatsApp Marketing and how does it work?

WhatsApp marketing is the modern way to reach customers quickly and personally. Through WhatsApp newsletters, automated chats, and targeted messages, you stay in touch with your customers – right on the device they use every day. No spam, no waiting – just real communication.

WhatsApp offers tremendous functionality. You can share videos, images, texts, and links, get reactions, and reply instantly. End-to-end encryption ensures security. The terms of use allow marketing under certain conditions – and we at Chatarmin show you how to stay compliant.

Unlike email, no lengthy sign-up is needed. A simple opt-in is enough, and you can launch your WhatsApp newsletter. The open rate? Significantly higher than classic email. Why? Because people use WhatsApp – it’s fast, familiar, and part of daily life.

Instant messaging vs traditional email

The biggest difference between instant messaging and email is speed. WhatsApp messages are read within seconds, emails often sit unread. In today’s fast-paced world, speed matters – those who wait lose. Especially in marketing campaigns promoting timely offers, speed is key.

Another factor is tone. While emails are often formal, WhatsApp allows you to speak casually and directly to your customers. This creates closeness and trust. You can tailor content, respond quickly, and adapt to your audience.

Still, both channels have strengths. WhatsApp is ideal for quick info and direct communication, while email excels with detailed newsletters, official letters, and formal offers. The art lies in finding the right mix.

User behavior and reach – How many people use WhatsApp worldwide?

WhatsApp is no longer a secret – over 2 billion people use the messenger worldwide. In Germany, nearly every smartphone has it installed. Especially interesting: daily usage often exceeds 30 minutes. That means you’re present exactly where your customers are active.

Thanks to this reach, WhatsApp marketing isn’t just for younger audiences. Older generations also use it to stay in touch with family, friends – and businesses. This opens up new ways to integrate marketing into your customers’ everyday life.

Also important: WhatsApp messages are read almost instantly. No waiting, no barriers – direct access is invaluable. And with the right opt-in strategy, you’ll quickly build a loyal, engaged community.

Email users – Facts and figures

Despite the dominance of instant messaging, email remains a cornerstone of digital communication. With over 4 billion email users worldwide and billions of emails sent daily, the potential reach is massive – but actual use is another matter.

Many see email as a flood. A full inbox, spam, promotions – and your carefully crafted newsletter somewhere in the middle. The challenge is standing out. While email marketing offers lots of design flexibility, it’s useless without high open rates.

In industries like B2B or formal sectors, email remains essential – for contracts, invoices, and official communications. But for quick, personal messaging, WhatsApp often takes the lead.

Daily usage patterns

WhatsApp is always on. Users check messages multiple times an hour and reply instantly – it’s integrated into daily life. Emails, however, are typically checked at specific times: morning, noon, evening. These differences matter for your marketing strategy.

Reading behavior also differs. A WhatsApp message feels personal – short, direct, friendly. Emails are often skimmed, sorted into folders, or deleted. For quick engagement, the messenger wins. For detailed information, email holds strong.

In comparison: WhatsApp appeals emotionally; email handles depth. Use both strengths wisely!

Open rates and engagement for WhatsApp messages

Open rate is key in marketing. What good is the best message if no one reads it? This is where WhatsApp shines: with open rates over 90%, you reach almost everyone. That’s due not only to the app’s popularity but also because messages don’t land in spam.

At Chatarmin, we see daily how strong WhatsApp engagement is. Customers don’t just open – they respond, click, and interact. That’s due to the personal tone, direct delivery, and fast experience. A WhatsApp message is not ignored – it’s appreciated.

With high open rates, WhatsApp marketing is perfect for campaigns that require quick action: flash sales, event reminders, or exclusive content. For immediate results, WhatsApp is unbeatable.

How classic email newsletters perform

Traditional email newsletters have it tough. Average open rates range between 15–25%, depending on the industry. Many go to spam, are deleted, or never opened. Still, email remains valuable – when used properly.

Emails allow you to share detailed content, provide value, and build long-term relationships. Success depends on how well your list is maintained, your design, and topic relevance.

A well-crafted email newsletter can be powerful – but it requires more effort to gain attention. WhatsApp is spontaneous, email delivers depth.

Engagement: replies, clicks, and interactions

The real strength of a marketing channel is engagement. How do customers respond? At Chatarmin, we regularly see WhatsApp users not just reading, but acting. They reply, ask questions, click links, or share content. This makes WhatsApp marketing so powerful.

The direct approach makes the customer feel personally addressed. No long thought process like with formal email – a short message, a quick reply. It creates true dialogue, not just one-way communication. Especially for time-sensitive actions, WhatsApp excels.

In contrast, email engagement is often lower. Users click and respond – but it’s harder. The message must convince, arrive at the right moment, and stand out. You need strong subject lines, good design, and a clear call-to-action.

Feature comparison – WhatsApp vs Email

What do people love? Pictures, videos, GIFs – and this is where WhatsApp shines. You can create lively messages, evoke emotion, and enhance your content visually. Whether product videos, clips, or snapshots – it’s fast and easy.

WhatsApp goes beyond text. Use voice messages, send documents, even embed YouTube links. Your content becomes varied and exciting.

Email also supports multimedia – but with limitations. Not all clients display images properly, and videos often require links. You lose users if content doesn’t load immediately.

Chat functionality and real-time communication

Another huge WhatsApp advantage: real-time chat. You don’t just send – you talk. That’s true customer engagement. Customers feel heard, valued, and remain loyal.

Email takes longer. Replies must be written, may sit unread for hours. In an age of instant response expectations, this can be a disadvantage.

Email lists vs WhatsApp subscribers

Building an email list takes time. You need opt-in, trust, and ongoing value to keep subscribers. Still, many unsubscribe or ignore newsletters.

WhatsApp onboarding is easier. One opt-in and you’re in. Subscribers are more engaged and stick around longer. Chatarmin helps you build and grow your WhatsApp community.

Data privacy and security – End-to-end encryption on WhatsApp

In 2025, data protection is more important than ever. WhatsApp protects messages with end-to-end encryption. Only sender and recipient can read them – a major security benefit. For businesses, this means you can share sensitive content without fear.

Of course, you must follow terms of use. But that’s where we come in. Chatarmin ensures your WhatsApp marketing is legally safe. We know the rules – you stay GDPR-compliant and protect your customers’ data.

Email data privacy policies

Emails also have strict privacy regulations. You need legal opt-ins, must protect data, and inform subscribers transparently. Still, risks remain: spam filters, insecure servers, lack of encryption.

Many email services offer better security now, but it’s still effort. WhatsApp simplifies it: fewer technical hurdles, clearer functionality, more trust.

Spam folders – the email problem

A well-known email marketing issue: the spam folder. Even when done right, newsletters often end up unread. Filters get stricter, and small mistakes can bury your message.

Many businesses struggle to improve delivery rates. But it’s a constant fight against spam filters and technical hurdles. For smaller companies without expensive tools, it’s especially challenging.

How WhatsApp prevents spam

WhatsApp has no spam folder. Messages go straight to users – with valid opt-in. That makes delivery reliable and safe. Users can also block you anytime – fair and transparent.

WhatsApp’s terms also prevent spam. It’s not about reaching thousands uninvited – it’s about real, valuable communication. With Chatarmin, you stay compliant and use WhatsApp as intended: personal, direct, and spam-free.

Customer loyalty and engagement through personalization

Whether WhatsApp or email – personalization works. But WhatsApp gives you more ways to tailor messages. Send direct responses, share relevant content, and engage users effectively.

The app makes it easy to stay flexible. A customer asks something? You reply instantly. A promo fits a segment? Send it in seconds. This closeness builds loyalty – something email rarely achieves.

Fast responses and deep customer connection

In a fast-paced world, WhatsApp shines with instant replies. No waiting, no inbox hunting – just send, receive, respond. This builds real trust.

Chatarmin helps you establish that customer connection. Through personalized chats, automated messages, and relevant content, you stay top-of-mind – long term.
