What is Karix?

Karix is the enterprise messaging arm of Tanla Platforms, run from Karix Mobile Private Limited in Goregaon East, Mumbai, with a Dubai office for the Gulf. It sells SMS, WhatsApp Business API, Google RCS, Truecaller business messaging, email and voice through one set of APIs, plus campaign and chatbot tools on top. Karix says it serves over 2,000 customers, claims about 35% share of the Indian CPaaS market, and names brands such as Axis Bank, Croma, MakeMyTrip and CRED in its case studies.

Its strength is scale on Indian telecom routes. The SMS page quotes up to 80,000 SMS per second on its Power API, 20,000+ dedicated OTP transactions per second, OTP delivery under one second and 99.99% uptime. DLT registration and template approvals are automated, which saves the back-and-forth that trips up many Indian senders under TRAI's commercial messaging rules. Banks get extras such as SIM binding and SIM-swap checks, and Wisely ATP, an AI tool that blocks SMS phishing that uses a brand's name.

The catch for smaller buyers is that nothing is priced publicly. SMS, RCS and voice are quoted after a consultation, and WhatsApp follows Meta's conversation-category pricing plus Karix's own margin. There's no self-serve sign-up with a free credit pack like some smaller Indian gateways offer. If you send a few thousand promotional messages a month, a self-serve provider will be quicker to start with.

Karix makes sense when message volume, OTP reliability and compliance matter more than list price: banks, insurers, large e-commerce and travel firms, and government projects. Its Campaign Manager adds a journey builder across six channels, and Meta named it Partner of the Year in 2025. Expect a sales-led onboarding and a negotiated contract rather than a card payment.

What works well

  • +Very high published throughput: up to 80,000 SMS per second and 20,000+ OTP transactions per second
  • +Automated DLT registration and template approvals take care of India's commercial SMS rules
  • +One API covers SMS, WhatsApp, RCS, Truecaller, email and voice, with fallback between channels
  • +Wisely ATP uses AI to block SMS phishing that impersonates your brand, which matters for BFSI senders
  • +Security claims include AES-256 encryption of PII, VAPT and CERT-In audits, and Tier-III data centres
  • +Meta named Karix Partner of the Year (2025) for WhatsApp business messaging

What to watch out for

  • −No public price for any channel, so every buyer has to go through a sales consultation
  • −No self-serve free trial or starter credit is advertised on the website
  • −Built for enterprise volumes, so it's too heavy for a small shop sending a few thousand SMS a month
  • −WhatsApp costs combine Meta's per-category charges with Karix's margin, which makes quotes harder to compare
  • −The website gives headline marketing numbers but little detail on how case-study figures were measured

Best suited for: Banks, NBFCs and insurers that need fast OTPs, SIM-swap checks and anti-phishing protection · Large e-commerce, travel and retail brands running high-volume campaigns on WhatsApp, RCS and SMS · Enterprises that want one vendor for SMS, WhatsApp, RCS, Truecaller, voice and email · Teams that need DLT compliance handled by the provider
