How it works
Three steps to your first message — most teams are live before lunch.
Link WhatsApp, a sender number or your email domain. We handle verification, opt-in/opt-out lists and the compliance scaffolding for you.
Fire one typed API call, or compose and schedule from the dashboard — the same send pipeline powers both, across every channel.
import { WrNexusClient } from '@wrnexus/sdk'
// Reads WRNEXUS_API_KEY from the environment.
const client = new WrNexusClient()
await client.sms.send({
to: '+919812345678',
from: 'ACMEIN',
message: 'Your order ORD-4821 has shipped.',
})Watch delivery, reads, clicks and retries in real time, with webhooks and unified analytics built in from day one.
One platform
One typed API, one dashboard and one set of webhooks across every channel.
Send WhatsApp, SMS and email through one consistent request shape and auth model — no five-vendor stitching.
Verified senders, domain authentication (SPF/DKIM/DMARC) and automatic retries keep your messages landing where they should.
Track sent, delivered, read, opened and clicked across channels in real-time dashboards — and export the raw events.
Opt-in consent, STOP/START and one-click unsubscribe are enforced for you, with per-channel suppression lists.
Subscribe to delivery and engagement events, or poll message status, and wire the results straight into your systems.
Schedule sends, run campaigns and reuse approved templates with merge variables across every channel.
Team workspaces, roles and secure accounts come standard — so the right people send, and everything else stays locked down.
Trust
Honest status on the standards that matter — no badges we haven't earned.
TLS 1.2+ in transit, AES-256 at rest, and HIPAA via signed BAA on Enterprise. Audit reports and our DPA are shared under NDA.
Customer stories
From OTPs to order updates to campaigns — here's what teams tell us.
We moved OTPs, shipping updates and promos onto WRNexus in a week. Delivery rates climbed and our on-call pages dropped.
Reported outcome: Delivery up to 99.5% · 60% fewer on-call pages
Asha Patil
Head of Engineering, Northwind
One API for WhatsApp, SMS and email meant we stopped maintaining three integrations. Read receipts alone cut our support tickets.
Reported outcome: 3 integrations consolidated to 1 · fewer support tickets
Rohit Menon
Product Lead, Lumen Retail
Opt-out and suppression handling is automatic, so our campaigns stay compliant without anyone babysitting lists.
Reported outcome: Opt-outs handled automatically · 100% list compliance

Common questions
Cost, compliance and ownership — answered up front. Need more? Book a demo and we'll walk your team through it.
Plans start free and scale with platform usage — email volume, sending domains, storage and automation. Paid plans are flat per workspace (seats aren't charged per head): Pro is ₹999/mo and Team is ₹2,999/mo, with around 17% off on annual billing. WhatsApp and SMS are always pay-as-you-go, billed per message on top of any plan. Prices are in INR with 18% GST on paid plans, billed via Razorpay.
WhatsApp and SMS run on prepaid, pay-as-you-go credits: you top up a credit balance and each message draws from it at its own per-message rate, so you only pay for what you actually send. There are no per-plan WhatsApp or SMS message allowances to outgrow. Email is the one channel metered by your plan — each plan includes an email send allowance, and once you pass it, extra sends draw on the same prepaid credits. Credits don't expire, and you can set up auto-recharge so high-volume sends never stall.
Opt-in consent, STOP/START keywords and one-click unsubscribe are enforced automatically across WhatsApp, SMS and email. Opted-out contacts go onto per-channel suppression lists and are blocked from future sends, so your messaging stays compliant without manual list-keeping.
Your data is yours. Export contacts, messages, delivery logs and analytics anytime via the API or dashboard in open formats — no lock-in and no exit fee. Cancel and your export still works.
Cloud data is hosted in the EU or US, and you choose your primary region at signup. APAC and custom data-residency are available on Enterprise, so regulated teams can keep data within a specific jurisdiction. Backups are retained in the same region as your primary data, and we'll document the exact storage locations in your DPA.
We're transparent about exactly where each programme stands. GDPR and CCPA controls are live in production today. Our SOC 2 Type II audit is in progress — currently in its observation period — and HIPAA is available via a signed BAA on Enterprise. ISO 27001 is on our 2027 roadmap and is not yet certified. We never claim a certification we don't hold; current audit reports and our DPA are shared under NDA.
Every public endpoint runs TLS 1.2+, passwords are hashed with Argon2id, and high-sensitivity data is encrypted at rest with AES-256. We take nightly backups with quarterly restore drills and commit to notifying you of any qualifying breach within 4 hours. Secure accounts, passkeys and workspace isolation come standard.
Minutes. Sign up free, confirm your email, and your first email can go out straight away — there's no onboarding project, sales call or contract to clear first. WhatsApp and SMS just need a quick prepaid top-up and a one-time sender or number verification, the only step that can add a short wait. Most teams are live the same day they sign up.
