SMS, WhatsApp and email — from one API
SMS Buddy is customer messaging for Sri Lankan businesses. Wire up once and send order updates, reminders and campaigns over SMS, WhatsApp or email — reliable, and connected to the systems you already run.
What is SMS Buddy?
SMS Buddy is a messaging service that sends SMS, WhatsApp and email through one API. You integrate once and pick the channel per message, instead of wiring up and paying for three separate providers. It's built to connect to your systems, so order updates, OTPs and reminders send themselves off events you already have.
the cost of the old way
What SMS Buddy replaces
Three channels, three providers, three bills
Today
SMS through one vendor, WhatsApp through another, email through a third — three integrations to maintain and three invoices to reconcile.
With SMS Buddy
One API, one account, one bill. You pick the channel per message and the routing is our problem.
Updates sent by hand, or not at all
Today
Order confirmations and delivery updates depend on someone remembering to type them — so on busy days, exactly when they matter most, they stop.
With SMS Buddy
Messages fire off events you already have. A paid order confirms itself; a dispatched delivery announces itself.
OTPs that arrive after the customer gave up
Today
Slow international routes mean verification codes land a minute late — and the signup or payment is already abandoned.
With SMS Buddy
Local gateway channels deliver passcodes in seconds, with rate limiting so the endpoint can't be farmed.

is this you?
Built for some businesses — honestly not for others
SMS Buddy is built for you if…
- Developers and SaaS teams who want one messaging integration, not three
- Businesses sending OTPs where seconds decide whether the signup completes
- Retail and delivery operations that should confirm every order automatically
- Teams running promotions who want segments, schedules and delivery reports
It's probably not for you if…
- One-off manual blasts from a spreadsheet — cheaper tools exist for that
- Teams with no system to trigger from and no plan to build one — the value is in the wiring
If you sit in the second column, we'd rather tell you now than after an implementation. Book the walkthrough anyway — we'll point you at the right-sized option, even when it isn't ours.
Who it's for
SaaS platforms, fintech startups and enterprise operations.

What channels does SMS Buddy support?
SMS Buddy sends over SMS, WhatsApp and email through one API. You integrate once and choose the channel per message — a transactional alert over SMS, a richer update over WhatsApp, a receipt over email — instead of wiring up and paying for three separate providers.
Can I connect it to my existing systems?
Yes. SMS Buddy is built to be called from your own applications and from Nanobotz products like POS, so messages fire off events you already have — a paid order, a booking, a low-stock alert — without anyone sending them by hand.
Is the WhatsApp channel the official API?
Yes — SMS Buddy integrates the official WhatsApp Business API, with pre-approved templates, interactive buttons and chatbot flows. That matters because unofficial bridges get numbers banned, usually at the worst possible moment.
How fast do OTPs actually arrive?
Average OTP delivery is 1.8 seconds over local gateway channels, with rate limiting and verification logic built in so you don't build them yourself. When a passcode races a customer's patience, local routing is what wins.
Can it handle bulk campaigns without melting?
Yes. The platform moves over 12 million messages a month and absorbs broadcast spikes without throttling. Campaigns can be scheduled ahead and filtered by segment, so the right offer reaches the right customers instead of everyone.
How much does SMS Buddy cost?
Messaging is usage-based and rates differ by channel, so we quote against your expected volume and mix rather than publishing one figure. Book a walkthrough and we'll put real numbers next to how you'd actually use it.
