What people use each for

The jobs each tool is most often brought in to do.

Knowlarity

  • An Indian business needs call tracking against marketing campaigns using virtual numbers with an all-India single rate rather than circle-by-circle pricing.not OneSignal
  • A marketplace or delivery operation must connect customers and riders without exposing either phone number, which is what the number masking product exists for.not OneSignal
  • A company running rural or low-data campaigns wants missed call as a lead capture and opt-in channel, which has no equivalent in Western telephony platforms.not OneSignal
  • An Indian contact centre wants published per-agent pricing it can budget against instead of the quote-only approach taken by Ameyo, Genesys and the international vendors.not OneSignal

OneSignal

  • Sending push notifications to mobile app users when orders shipnot Knowlarity
  • Triggering email confirmations based on form submission eventsnot Knowlarity
  • Creating multi-step SMS and email journeys for onboarding usersnot Knowlarity
  • Sending in-app messages to users abandoning checkout flowsnot Knowlarity

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Knowlarity

  • It is sold only in India and the UAE, so an organisation outside those markets cannot buy it at all regardless of how well it fits.
  • Ownership by Gupshup means voice sits inside a messaging-first company, and the strategic emphasis and investment now favour WhatsApp and conversational messaging over the traditional telephony line.
  • Published pricing covers the contact centre agent seats, but numbers, minutes beyond bundles, SMS, WhatsApp conversations and speech analytics are separate charges, so the monthly bill is materially above the headline per-agent figure.
  • SMS in India requires DLT registration of headers and templates under TRAI rules, and that compliance overhead falls on the customer, delaying campaign launches in a way buyers from other markets do not expect.
  • The contact centre feature depth, reporting and workforce management are thin next to Genesys, Five9 or NICE, so a large or complex operation will find quality management and forecasting missing rather than merely simpler.

OneSignal

  • Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
  • Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier
