Messengers for Business: Where to Launch Mass Messaging — WhatsApp, Telegram or Viber?
Messengers have become essential tools for modern businesses — especially when it comes to direct communication with customers. Today, messenger marketing via WhatsApp, Telegram, and Viber is not just an alternative to email; it’s a fully-fledged channel for sales, support, and brand engagement. But which messenger should you choose to get the best results?
Why Messengers Outperform Email

One of the strongest arguments for messenger-based marketing is the extremely high open rate. While email newsletters typically reach a 20–30% open rate, messages sent via messengers often achieve 90% or more. Why? Because people always have their smartphones nearby — and notifications from messaging apps are hard to ignore.

Other key benefits include:

  • Wider reach — millions use messengers every day, and such communication feels more personal and trusted.
  • Speed — messages are delivered instantly, and replies often come within minutes.
  • Engagement — messenger formats support text, images, videos, buttons, polls, and other interactive elements.
Let’s compare the top three platforms and their capabilities.
WhatsApp: Most Popular, but with Limitations

A solid WhatsApp marketing strategy is ideal for businesses aiming to reach a large audience. According to Mediascope, around 67% of Russia’s population use WhatsApp, making it one of the country’s most widespread communication tools.

Messaging Options:

  • Personal account — for microbusinesses with up to 256 contacts saved in your phonebook.
  • WhatsApp Business app — supports up to 1,000 messages per day and allows automation.
  • WhatsApp Business API — a professional solution for large businesses, integrated via official providers.
  • Integration with CDP platforms (e.g., Altcraft) — enables fully personalized, automated messaging based on customer data.
Another major advantage is the ability to maintain two-way communication. Customers can reply to messages directly, making WhatsApp a powerful tool not just for broadcasting but also for support and conversion. Combining automated replies with human operators can create seamless and responsive customer journeys.
Telegram: Flexibility, Automation, and Audience Growth

Telegram promotion and targeted messaging campaigns are growing rapidly, especially among younger, privacy-conscious users.

Messaging Tools:

  • Channels and groups — perfect for news, promotions, and content updates.
  • Telegram bots — allow for personal messaging, quizzes, automated replies, and advanced user scenarios.
To set up messenger marketing in Telegram:

  1. Create a bot via @BotFather.
  2. Connect it to a messaging automation service (such as Altcraft).
  3. Build your subscriber base and ensure you have their consent.
  4. Prepare engaging, multi-format content.
  5. Segment your audience and time your campaigns strategically.
What makes Telegram truly stand out is its automation flexibility. After receiving a message, users can interact with buttons, join polls, or receive tailored offers — all within one conversation. This makes Telegram ideal for interactive campaigns and content-driven strategies.
Viber: Niche Tool with Visual Potential

While not as dominant as WhatsApp or Telegram, Viber business messages still play a role in certain countries and industries — especially in Belarus and parts of Eastern Europe.

Key Points:

  • Free accounts can send messages to no more than 50 contacts daily.
  • For large-scale campaigns, integration with CDP platforms like Altcraft is essential.
  • CDPs enable automation, personalization, segmentation, and analytics.
A unique benefit of Viber is its visual approach: messages can include banners, call-to-action buttons, media files, and product cards — turning a regular message into an eye-catching ad unit. This makes it especially effective for product promotions and visual storytelling.
Why Personalization Is Critical

Whether you're using WhatsApp marketing strategy, Telegram promotion, or Viber business messages, personalization is the game-changer. Generic bulk messages no longer deliver results — customers want communication that’s relevant, timely, and personal.

With modern CDP platforms, businesses can:

  • Collect data from websites, CRM, social networks, and messengers;
  • Segment users based on interests, activity, or purchase behavior;
  • Launch trigger-based message flows that react to user actions;
Build loyalty through relevant and timely offers.
