Every SaaS product and ERP system depends on messaging working invisibly in the background — the OTP that lets a user log in, the alert that fires when inventory runs low, the notification that confirms an action completed. MetaReach Marketing provides the OTP, WhatsApp, SMS, Email, and Voice infrastructure that SaaS platforms and ERP providers integrate into their own products — DLT-compliant, developer-first, and built to scale from a handful of end-users to millions.
Quick Answer
MetaReach provides five core messaging capabilities that SaaS and ERP platforms integrate via API: OTP authentication for login/2FA, WhatsApp notifications for in-app alerts, Bulk SMS for ERP-specific alerts (invoice, inventory, HR), transactional email, and IVR for customer support escalation. We're the messaging infrastructure layer — your platform and its logic remain yours to build.

This is fundamentally an integration problem, not a marketing-messaging problem — which is why API-first design matters more here than almost any other vertical MetaReach serves.
