CPaaS, explained
What is a CPaaS platform?
CPaaS (Communications Platform as a Service) is a cloud platform that connects your business to your customers’ phones and inboxes. Instead of signing up with a different provider for SMS, WhatsApp, calls and email, you use one dashboard and one API for all of them.
Our platform handles the parts that usually slow businesses down: DLT registration for SMS, WhatsApp Business onboarding and template approvals, delivery across networks and fallback to another channel when a message does not arrive. Your team gets one place to send, track and reply.

RCS Business Messaging
Send app-like messages to the default Android messages app: your logo, a verified brand name, images, carousels and buttons, with no app to install.

WhatsApp Business API
Message customers where they already are. Send offers, alerts and support replies on WhatsApp at scale, from one number your whole team can use.

WhatsApp Chatbot
Answer every WhatsApp message in seconds, even at 2am. Our chatbots handle common questions, collect lead details and book appointments, then pass the chat to your team.

Email API & SMTP
Send receipts, password resets, invoices and newsletters from your app or website, with the domain setup and tracking that keep them out of spam.

2-Way SMS, Long & Short Codes
Turn one-way alerts into conversations. Customers text a keyword or reply to your message, and the reply reaches your team or triggers an automatic response.

What is CPaaS?
CPaaS stands for Communications Platform as a Service. It is a cloud platform that lets businesses send and receive SMS, RCS, WhatsApp messages, voice calls and emails through one dashboard and API, without building telecom connections themselves.
Is Zenspire's CPaaS platform DLT registered?
Yes. Our platform is DLT registered for commercial SMS in India, and we help every client register their business, sender headers and message templates before they send.
Are you an official WhatsApp Business API provider?
We are a Meta WhatsApp Business Partner. We set up your WhatsApp Business API account and number, get templates approved and run campaigns, alerts, chatbots and your team inbox from our platform.
Which channel should I use?
It depends on the message. OTPs and alerts suit SMS for reach, WhatsApp and RCS suit rich marketing and support conversations, voice suits reminders and helplines, and email suits invoices and long updates. Most businesses use two or three channels with fallback between them, and we help you choose in the demo.
Can I use the platform through an API?
Yes. Every channel is available through the same REST API with webhooks for delivery reports, reads, clicks and replies, as well as through the web dashboard.
How is the CPaaS platform priced?
Pricing depends on the channels you use and your monthly volume. We do not list prices on the site. Book a demo and we will send a written quote after the call.
Can agencies resell the platform?
Yes. Our white label CPaaS lets agencies, software companies and resellers offer all channels under their own brand, with their own prices and client sub-accounts.
