The Challenge
SMS Alone Can't Keep Up
Your customers expect rich, interactive experiences. But plain-text messaging and fragmented channel management hold you back.
Plain SMS Gets Ignored
Text-only messages disappear in crowded inboxes. No images, no buttons, no branded content. Open rates drop and customers tune out.
One Channel Per Provider
RCS with one vendor, WhatsApp with another, SMS with a third. This means managing multiple dashboards, contracts, and analytics — all of which must be reconciled separately.
Messages Fail Silently
When a message can’t be delivered on a specific channel, the delivery attempt simply ends. Without automatic fallback or retry mechanisms, businesses may never know that the customer did not receive the message.
The Solution
How Kero Works
Kero unifies RCS, WhatsApp, and SMS into a single platform — one dashboard, one campaign builder, one set of analytics, and intelligent fallback so every message reaches its target.
Rich Messages That Get Tapped
Send rich, branded messages with images, videos, carousels, and interactive buttons that get customers tapping — not just reading.
- Branded carousels, images, and interactive buttons in every message
- Customers engage instead of scrolling past — messages worth tapping
- Automatic fallback to WhatsApp or SMS if RCS isn't available
Verified and Trusted Across Every Channel
Verified sender identities, branded profiles, and encryption mean your customers always know who's messaging them — and trust what they see.
- Verified sender identity on RCS and WhatsApp
- Your logo, brand colours, and company name on every supported channel
- End-to-end encryption and validated content templates
One Dashboard, Every Channel
No more juggling three vendors. One platform, one campaign builder, one bill — with real-time analytics to optimise campaigns as they run.
- RCS, WhatsApp, and SMS analytics unified in one view
- Real-time delivery, read, and interaction metrics
- Clean JSON API to integrate with your existing systems

Everything you need to know about getting started with Kero.
RCS pricing varies based on usage, destination, and network. Kero provides flexible, scalable pricing to suit businesses of all sizes — without the high-volume commitments often required by enterprise providers. Adoption is growing rapidly as RCS expands globally, and with built-in SMS fallback, your messages are always delivered reliably.
Yes. Kero provides a clean JSON API that connects with your CRM, marketing automation, and backend systems. Integration is straightforward and our team provides hands-on support throughout the process — you won't be left navigating docs alone.
You don't have to abandon SMS — Kero includes it as a fallback channel. The value is adding rich, interactive channels (RCS and WhatsApp) alongside SMS in one platform, so you can upgrade your customer experience without managing multiple providers.
Kero is a focused messaging specialist, designed to simplify customer communication. That means faster onboarding, hands-on support from real people, and deep expertise in RCS, WhatsApp, and SMS — without the complexity typically associated with large enterprise platforms.
Kero automatically falls back to the next available channel. If RCS isn't supported, the message routes to WhatsApp. If WhatsApp isn't available, it falls back to SMS. Every message gets delivered — no silent failures.
Kero is an official WhatsApp Business API partner. This means you get verified WhatsApp messaging with templates, rich media, and interactive buttons — all managed alongside RCS and SMS from a single dashboard.
Kero provides SMS as both a standalone channel and an automatic fallback. You get delivery reports, link tracking, and the same campaign builder used for rich messaging — with global coverage.
Guaranteed delivery means Kero attempts every message across your configured channel cascade, using SMS as a universal-reach fallback, and returns a definitive delivery status for each attempt. It does not guarantee receipt where a number is invalid, unreachable, opted out, or blocked by a carrier or handset.
Kero can't guarantee receipt where the number is invalid or unreachable, where the handset stays off or out of coverage past message expiry, where the recipient has opted out or is on DND, where a carrier blocks or filters the traffic, or where content is rejected on regulatory or policy grounds, including WhatsApp's 24-hour window and template approval rules. "Delivered" means handed to the network or handset, which is distinct from "read."
