Viber — the messaging heartland of Central & Eastern Europe

Reach Viber audiences with the same rigor you apply to SMS.

Viber Business Messages for transactional notifications, promotional campaigns and conversational flows. Official Rakuten Viber partnership, verified sender branding, SMS fallback when the user is not on Viber. One integration, measurable results.

The problem we solve

Your customers use Viber. Your marketing stack pretends they do not.

In Italy, Greece, the Balkans, CIS countries and parts of South-East Asia, Viber is often the default messaging app. Ignoring it means missing the channel where your audience already spends time. But Viber has its own rules on sender verification, template approval, session billing, and SMS fallback — and those rules reward operators who know the platform.

  • Verified branded sender with logo and business name on every message
  • Transactional, promotional, one-way and two-way messaging — each with its own pricing tier
  • Automatic SMS fallback to guarantee delivery when the user is not on Viber
  • Template approval workflow and Viber quality rating monitoring, managed end to end
How it works

From setup to scale, in four steps.

1

Business onboarding

Viber business account setup, logo and brand verification, sender ID registration in target markets.

2

Templates

Template design and submission across transactional, promotional and two-way categories, with approval tracking.

3

Integration

REST API for send and webhook for inbound and delivery events. Same connector handles Viber and SMS fallback.

4

Scale

Per-market performance review, template iteration, cost per delivered message, fallback ratio optimization.

What you get

Built for teams that care about results.

Verified branded sender

Your logo and business name appear on every Viber message. No impersonation, no grey routes.

All message types

Transactional, promotional, one-way and two-way — we configure the right mix for your use case and budget.

Rich media and CTAs

Images, videos, buttons, links. Engage with content the SMS channel simply cannot deliver.

Automatic SMS fallback

If the recipient is not on Viber, we transparently deliver via SMS with equivalent content and the same API call.

Regional route expertise

Direct Viber routes in Italy, Greece, CEE, CIS and SEA — where Viber matters most.

Unified analytics

Delivery, read, click-through, fallback ratio, cost per conversion — measured per market and campaign.

Use cases

Where this makes the biggest difference.

Transactional notifications in CEE and CIS

Order confirmations, shipment alerts, authentication codes delivered via Viber where adoption is highest, SMS fallback elsewhere.

Branded promotional campaigns

Rich-media offers with images and CTAs to your opted-in Viber audience, segmented by region and behavior.

Conversational customer care

Two-way Viber sessions for support, handled by chatbot or routed to live agent with full context.

Travel and hospitality confirmations

Branded booking confirmations, check-in instructions, travel advisories in the messenger your customer already uses.

Technical integration

One endpoint. Viber and SMS fallback handled transparently.

You call a single REST endpoint. We route via Viber when the recipient is reachable, fall back to SMS when not, and unify the reporting. Template management, sender approval and quality monitoring are operated on your behalf and visible in the same dashboard.

  • REST API with unified send for Viber + SMS fallback behind one call
  • Template CRUD: transactional, promotional, one-way, two-way with approval tracking
  • Webhooks for delivery, read, click and inbound events
  • Media upload with automatic size and format validation for Viber constraints
  • Per-market quality and sender monitoring with alerting
  • Simulation mode and sandbox for integration testing

FAQ

Frequently asked questions

In which countries does Viber make sense?
Viber has dominant or significant adoption in Italy, Greece, the Balkans, Ukraine, Belarus, Russia, Kazakhstan and other CIS countries, plus Myanmar, the Philippines and parts of SEA. We advise per-market based on actual reach data.
What is the difference between transactional and promotional Viber messages?
Transactional messages are pricing-favored and reserved for informational, service-critical content (OTPs, receipts, alerts). Promotional messages allow marketing content with richer media but require explicit opt-in and follow stricter quality rules. We help you categorize templates correctly.
How does SMS fallback work?
If the recipient does not have Viber installed or is unreachable within the fallback window, we automatically deliver the equivalent content via SMS. You call one API; our routing handles the branching. Analytics report Viber-delivered vs SMS-delivered so you can measure the mix.
Do I need a separate Viber business account?
Yes, Viber requires a verified business account with logo and business name approval. We handle the submission, follow-up and approvals, typically in 1–2 weeks.
Can I run two-way conversations on Viber?
Yes. We configure two-way sessions so your customers can reply to a Viber message, with inbound routing via webhook to your chatbot, CRM or agent console. Pricing on two-way Viber sessions is distinct — we explain the model before activation.
Is Viber more expensive than SMS?
Viber transactional messaging is typically cheaper than SMS in its heartland markets and offers much better engagement. Promotional Viber costs more than SMS but converts at a higher rate. We model cost per conversion, not cost per message.
