WhatsApp First. SMS as the Safety Net.
Reach customers where they actually read: on WhatsApp, from a verified business number, direct with Meta - and by SMS automatically when WhatsApp can’t deliver. One engine, one API, one bill. It’s the same Notify engine that sends for Gyte, Kesho, Heita and Konnector, sold standalone, with a local team who picks up the phone.
One Account, Many Ways to Send
Compose a campaign on your laptop, and your customers reply straight from their phones. Illustrative screens — the real Voimar SMS layout, sample data.

Not Another Reseller Storefront
Most bulk SMS platforms are a login screen bolted onto someone else’s gateway. Voimar SMS is the same engine we run our own business on.
WhatsApp First. SMS as the Safety Net.
Most of your customers read WhatsApp before SMS. Bring your own WhatsApp Business number and we integrate it: your messages go out on WhatsApp first, under your own verified business name, and if one isn’t delivered in time the same message goes out as an SMS automatically.
Live - direct with Meta, no middleman- 1
Your Own WhatsApp Number
Bring your WhatsApp Business number - we connect it to Voimar through Meta's official onboarding. Your name, your number, your reputation: nothing you share with other senders.

Automatic SMS Fallback
Not delivered within about 45 seconds, or rejected? The same message is sent by SMS, with no action from you.

Pay Once
WhatsApp notices and codes cost R0.30 - about half the price of an SMS. You're billed once per message, for whichever channel delivered it.
Bring your own WhatsApp Business number - we integrate it
- Every business sends from its own WhatsApp Business number and verified name - never a shared one. One sender’s mistakes can’t block anyone else.
- We connect your number to Voimar through Meta’s official onboarding, set up your message templates, and route everything through one API and one bill.
- Messages use Meta-approved templates (notices, receipts, reminders, codes and campaigns), sent only to people who opted in. Customers can reply, and replies reach you - a two-way line, not a one-way blast.
- Don’t have a WhatsApp Business number yet? We’ll help you register one. Until it’s connected, your messages go by SMS.
