How your message routes

01 Direct interconnect Traffic hands straight to Vodacom, MTN, Cell C and Telkom — no daisy-chain of resellers between you and the handset.

02 Automatic failover If a route slows or drops, the message re-routes to another and you still get exactly one delivery report.

03 One report, four channels WhatsApp, Telegram, SMS and USSD land in the same reporting view, timestamped message by message.

04 Opt-outs honoured Suppression lists are applied on every send, across every channel, before the first message leaves the queue.

Mr Muscle 2026 Consumer Promotion, for SC Johnson.

Shoppers buy two Mr Muscle products, photograph the till slip and send it to 078 760 4132 on WhatsApp. The line carries the client's brand name, and Stouf runs the prompts, verification handling and entry reporting behind it.

What we do

One platform for every message you send.

From a one-off competition line to millions of transactional messages a month. Pick a service to see how it works — then tell us your volumes and we'll quote you.

The channel your customers already use, run properly: a verified sender, approved templates and a real inbox behind it. Start a conversation with a template, then carry it live within the session window.

Verified business profile and display name
Template and session messaging
Buttons, lists, media and documents
Two-way replies routed to your team or system
Competitions, fundraisers and voting on your own line

The workhorse. Send hundreds or millions of messages from our user-friendly system, or automate the lot through your own platform. Reaches every handset on every network — no app, no data.

Send yourself or fully automate
Full delivery reports on every message
Scheduling, recurring sends and sender ID
Two-way replies and keyword handling
Free sample code to get started

Your own dedicated shortcode — the *120*288# kind — driving menu journeys that work on the most basic phone, with no airtime for data and nothing to install.

Dedicated shortcode registered to you
Menu-driven entries, votes, donations and surveys
Works on every handset in the country
Live entry and session reporting
Rate-per-entry options for competitions

One-time pins, balance alerts and service notifications on priority routing, with retries and failover across networks so the message lands while it still matters.

Priority routing ahead of bulk traffic
Automatic retry and cross-network failover
Timestamped audit trail per message
Throughput sized to your peaks
Delivery callbacks into your system

HTTP API for web and desktop applications
SMPP bind for high-volume traffic
Delivery receipts and two-way callbacks
Sample code and setup support included

Send and receive SMS from the email client your team already has open. No training, no new system — an address becomes a send channel and replies land back in the inbox.

Send SMS straight from Outlook or Gmail
Replies returned to the sending inbox
Per-user permissions and limits
Full reporting alongside every other channel

We manage the database of numbers behind your campaigns: cleaned, de-duplicated, invalid data removed, opt-outs honoured — and a full report back to you every time.

Number cleaning and validation
De-duplication across lists
Opt-out suppression on every send
Full reporting after each clean

Mobile surveys, voting lines, donation lines and market research run over SMS, USSD or WhatsApp — with the results collected, deduplicated and reported as they come in.
