Viber marketing: how to plan campaigns that convert (2026)

What is Viber marketing?

Viber marketing is the use of Rakuten Viber's business tools to reach, convert and support customers inside the app. Brands use it for campaigns, like offers and launches, and for service messages customers want, like delivery updates and appointment reminders. It runs on two products, Business Messages and chatbots.

Viber marketing can look like this:

• Cart reminder. A short message with a link back to checkout.
• Review request. A message a day or two after delivery asking how the order went.

Where does Viber fit?

Viber works best where your customers already use it and your message is time-sensitive. SleekFlow's Viber page describes the user base as concentrated in Eastern Europe and Southeast Asia. Your own data is a better guide than any regional average, so check signup country codes, website traffic by region and the apps customers mention in support chats.

When should you hold back?

Hold back when your opt-in list is small or the content needs a formal record. A short list of willing subscribers beats a long list of strangers, and a Viber chatbot messages its subscribers. For contracts, policies and tax documents, email stays the record.

How does Viber work alongside other channels?

Give each channel a clear job and let each customer's habits decide. If a customer opens every Viber message and ignores every email, move more of that conversation to Viber. Viber's Business Messages page says delivery uses SMS as a fallback for reliability, but SleekFlow's Viber connection doesn't list that feature.

What are the two Viber products?

Viber offers two routes for business messaging, and they're easy to mix up. Business Messages cover notifications and promotions, with an SMS fallback. Chatbots work in sessions and are what SleekFlow connects to. Pick one before you plan, because formats, costs and approval steps differ.

How do you design a Viber campaign?

A good Viber campaign has one goal, one audience segment and one call to action, set before you write any copy. Pick a tight group instead of your whole contact list, and decide your success metric before you send.

The four steps in order:

1. Define the objective. For example, recover abandoned carts.
2. Choose the segment. Pick customers who share one recent action.
3. Pick the message. Match it to one next step.
4. Set the success metric. Decide the target before you send.

Every message needs one main call to action, because two competing links split attention. If you have two things to say, send two messages a few days apart.

How do 24-hour sessions affect campaign cost?

On Viber chatbots, messages your chatbot starts are paid, and the rate depends on the subscriber's country code. When a subscriber messages the chatbot, or replies to one of its messages, a 24-hour session opens, and messages inside it aren't billed. Plan campaigns that invite a reply.

A message like "Reply YES to reserve yours" shows who's interested and lets you follow up with sizes or time slots in the same chat. Viber's commercial model FAQ sets out these billing rules, so read it before you budget.

How do you measure and improve a Viber campaign?

Judge each campaign against the target you set before sending, change one thing at a time so you know what made the difference, and personalize with what a customer did. Click-through rate, conversion rate, revenue per message and campaign return show whether it worked.

Two made-up examples:

• A retailer that sends 10,000 messages and earns US$6,000 in attributed sales makes US$0.60 per message.
• A travel brand with a 12% click-through rate and a 1% conversion rate has a message that works and a landing page that doesn't.

After each campaign, watch for unsubscribes, complaints like "Why am I getting this?" and drop-offs between read and click.

What consent rules apply to Viber marketing?

Viber limits who a business can message, and consent and marketing rules also differ by country. Its Business Accounts Terms, updated 16 Aug 2026, say a business may start chats only with users who are its customers and have its contact details saved.

The same terms ban spam and unsolicited messages. Some markets add telecom or privacy requirements, so ask local counsel which rules apply where you send.

We suggest four habits, and each one is easy to check.

• Ask clearly. Ask for opt-in during checkout or signup, never with a pre-ticked box.
• Set expectations. Say what customers will receive and roughly how often.
• Make opting out easy. Include a way to stop in every promotional message. Viber's Terms of Use say users can unsubscribe from any chatbot at any time.
• Keep a record. Note when and how each customer opted in.

Viber's FAQ says a chatbot can send one unbilled welcome message before a user subscribes. Use it to say what people will get and how often.

How does SleekFlow support Viber marketing?

SleekFlow connects your Viber chatbot to the workspace your team already uses, so Viber chats don't sit in a separate app. SleekFlow's Help Center lists what the connection supports: multiple chatbots, sending and receiving messages, broadcasts, and a shareable QR code and link.

In practice, your team gets:

• One inbox. Viber chats sit in SleekFlow's shared inbox, next to your other channels.
• Broadcasts. Broadcast campaigns go to your Viber subscribers.
• Automated replies. Flow Builder can send automated replies to Viber chats.
• A link and QR code. Place them on receipts, packaging and your website to grow your subscriber list.

The Viber connection doesn't support:

• Rich media or carousel content
• Contact cards
• Location messages
• Stickers
• Some file types

The Help Center says a feature it doesn't list isn't supported, so check it before you plan around anything else.

How do you connect a Viber chatbot to SleekFlow?

New Viber chatbots aren't self-service. You apply to Viber directly or through an official partner, and SleekFlow's Help Center says approval isn't guaranteed. With a bot token, you add Viber as a channel in SleekFlow, paste the token and share the link and QR code it generates.

The Help Center's Viber connection guide lists the steps for a workspace Admin:

1. Open the Channels page and select Viber.
2. Click Connect.
3. Enter an account name, a channel name and the bot token.
4. Click Connect, then copy the link or save the QR code.

Plan your launch date around Viber's review, which is the slow step.

Where should you start with Viber marketing?

Start with one check: do your customers use Viber? If they do, pick the product, request approval early and design your first campaign around one goal. Then connect the approved chatbot.

SleekFlow's Viber integration page shows how the connection brings Viber into one shared inbox.
