Viber Bulk Messaging: How It Works and When It Makes Sense for Indian Businesses

When Indian businesses think about messaging apps for marketing, WhatsApp comes first, SMS second and RCS is growing. Yet some owners search for a different name: Viber. Perhaps a customer overseas uses it, an export partner insists on it, or a messaging vendor offers it as a cheaper option. Before investing time and money, it helps to understand what Viber bulk messaging actually is, where it works well and whether it deserves a place in an Indian marketing plan.

What Viber is

Viber is a messaging and calling app owned by Rakuten, the Japanese e-commerce and fintech group. Like WhatsApp, it offers chats, groups, voice and video calls, and a business offering for companies. Its strength is not evenly distributed around the world. Industry sources describe Viber as a leading messenger in several European countries, including Ukraine, Belarus, Bulgaria, Serbia, Greece and Moldova, and as a significant platform in the Philippines. In India, its presence is far smaller than that of WhatsApp, so it is rarely the main choice for reaching Indian customers.

How Viber business messaging works

Viber for Business offers several tools. The most relevant for marketers is Viber Business Messages, a channel for sending promotional, transactional and conversational messages to customers who have the app. Messages can contain more text than a standard SMS, with Viber documentation mentioning up to 1,000 characters compared with 160 for traditional SMS, and can include images, buttons and links. Businesses can obtain a verified profile with a blue tick, a company page and a dedicated business inbox folder inside the app, so customers know they are communicating with the official brand.

Companies usually access the channel through official partners and messaging platforms, using an API that works with CRM systems, websites and apps. Messages are priced per message, with rates varying by country and message type, and approved templates may be required for certain traffic types. As with other channels, pricing and rules vary by partner and region, so request a current quote.

What "bulk" means on Viber

There are two meanings. The first is sending a message to many contacts using the ordinary app. Some guides say that, similar to broadcast features in other apps, only contacts who have saved your number can receive such messages, and that app-based sending has limits on recipient numbers. This approach is meant for small groups of known people, not marketing at scale. The second meaning is using the business messaging service through a partner to reach opted-in customers at volume, with reports and API access. For any serious campaign, the second route is the proper one.

Should an Indian business use Viber?

For domestic marketing, probably not as a primary channel. WhatsApp, SMS and increasingly RCS reach far more Indian users. Viber may make sense in specific situations.

You serve customers abroad. Exporters, travel companies, education consultants and remittance or service businesses with customers in countries where Viber is popular may benefit from reaching them on the app they actually use.

Your customers or partners ask for it. If clients in a particular region prefer Viber for communication, supporting it removes friction.

You run multi-country operations. A platform that supports several channels lets you choose the best one per country: Viber in one market, WhatsApp in another and SMS as a universal fallback.

If none of these apply, your time is better spent on channels that reach your own customers.

Compliance and consent

Regulations apply wherever messages are received. Marketing messages on any app need proper consent, and customers must be able to opt out. Messaging apps in India are subject to the country's information technology rules, and businesses sending to customers abroad must follow local advertising and privacy laws in those countries. Use only opted-in contacts, keep records of consent and never buy lists.

How to evaluate a Viber messaging offer

Ask the provider whether they are an official partner of Rakuten Viber. Find out which countries you can reach, pricing per message, how templates and sender names are approved, how long onboarding takes and what reporting you get. Ask for delivery and read statistics, not just sent counts. Check that the platform supports fallback to SMS or WhatsApp for customers who cannot receive Viber messages. Be careful with sellers who offer unlimited cheap Viber blasts through unofficial methods, because such methods can violate the platform's rules and lead to blocked accounts.

Designing effective Viber campaigns

If you do use the channel, treat it as a rich messaging medium. Use images and buttons for a clear call to action, such as "View offer" or "Chat with us". Keep text concise even though more characters are allowed. Send at sensible times in the recipient's time zone. Use language that matches the customer, not just English. Segment audiences by country, interest and past behaviour. Track clicks, replies and conversions, and compare cost per result with other channels.

Better channels for most Indian businesses

For customers in India, WhatsApp Business Platform messaging offers reach, conversation tools and rich media. SMS remains the universal fallback and the standard for OTPs and alerts, with DLT registration required. RCS offers rich interactive messages to compatible devices. Voice and IVR serve customers who prefer calls. A mix of these will cover most needs, with other channels added when your customer base requires them.
