Built in Tanzania · Priced in shillings
Mlango sends WhatsApp Business messages for Tanzanian companies: receipts, confirmations, gate passes, reminders. You pay per message delivered, from a prepaid balance in shillings — never for one that fails to arrive.
No monthly fee. You pay only for messages that arrive.
Why Mlango
Not features. The questions every owner asks before trusting a system with their customer list and their money.
Two-step sign-in, a list of every device on your account, and the option to allow only your own office network. Unusual requests are challenged before they run, not explained afterwards.
Import straight from Excel — the system finds your phone column, fixes number formats, and shows exactly what will happen before anything is saved. No training course required.
Every campaign shows the cost per message and the total, in shillings, before you press send. Prepaid, so there is never an invoice at month end that you did not expect.
Pricing
WhatsApp charges by what a message <em>is</em>, not how long it is. A message confirming something your customer already did costs a fraction of one that promotes something. Most businesses never learn this and pay the higher rate for everything.
As a promotion
“You are invited to the wedding of Neema and Baraka on 12 September at the Diamond Jubilee hall. We would love to see you!”
Charged at the higher rate
As a receipt
“Dear Neema, we have received your contribution. This is your entry pass, number HR2K4VAY. Please show it at the door.”
Charged at a small fraction of it
Same guests, same event, same evening — several times the cost, purely in how it is written. Mlango tells you which category your wording falls into while you are still writing it, and shows the exact total for your list before you send.
Rates depend on your volume and where your customers are. Ask us for a quote — we will show you the figures for the messages you actually plan to send.
Security
Your account can send messages under your business name and draw down a real balance. That deserves more than a password.
A six-digit code from your phone, using any standard authenticator app. Ten recovery codes in case the phone is lost.
See what is signed in, from where, and when it was last used. Sign out anything you do not recognise, instantly.
Restrict sign-in to your office connection, so a stolen password is not enough on its own.
A large send from a device we have not seen, at an hour you do not normally work, asks you to confirm before it runs.
Let an assistant build campaigns without giving them the wallet, or a bookkeeper the reports without the contact list.
Anyone replying STOP or ACHA is removed at once and cannot be added back by a later import.
