Two-factor authentication
Run time-bound OTP flows with configurable expiry, attempt limits and clear verification outcomes.
emisiq by Emisri · Unified 2FA
One verification flow.Multiple ways through.
Unify two-factor authentication across SMS, voice and supported messaging channels. Integrate once, set your fallback policy and give customers another way to verify when the first route fails.
Built for developers and teams responsible for critical customer journeys.
One integration. Multiple ways to verify.
SMS
Voice
WhatsApp
RCS where supported
Unified authentication · with ENotifyMe
Verification built to keep moving.
The ENotifyMe API lets you manage OTP delivery, fallback rules, and verification outcomes through a single integration.
Multiple delivery channels
Use SMS and voice, with WhatsApp and RCS available where supported.
Route around failure
Configure fallback paths based on delivery events, channel availability, time limits and your application's priorities—not guesswork.
Control abuse and cost
Apply request limits, destination controls, spend thresholds and suspicious-traffic alerts to reduce avoidable abuse and unexpected messaging costs.
See what actually happened
Track request acceptance, delivery events, failures, retries and provider responses through a consistent event model and reporting view.
Integrate once
Give developers a consistent API and webhooks while Emisri handles channel-specific differences behind the integration boundary.
Configurable failover
If one route fails, try the next eligible route.
Set the order of channels, timeouts and retry limits. emisiq uses delivery events and your rules to decide when a verification attempt should move to its next route.
Rules you can configure
Choose primary channels, eligible fallbacks, timeouts and attempt limits to suit the use case.
Event-aware decisions
Distinguish pending, delivered, undeliverable, rejected and failed states before deciding what happens next.
Built to avoid message duplication
Use idempotency, delivery-event correlation and verification-session controls to reduce duplicate sends and conflicting OTPs.
Interactive routing preview

Choose an SMS outcome to see how the configured fallback policy responds.
1. SMS attempt
Delivery confirmation received
2. Voice fallback
Fallback cancelled by policy
3. Verification result
Delivery step completed; OTP verification is separate
Once SMS is delivered, the fallback sequence stops. The customer still needs to complete the verification step.
Security is part of delivery
Protect the communication path, not just the account.
Verification is a sensitive moment. emisiq's design puts limits, visibility and control around the systems that send the code or notification in the first place.
01 / Abuse controls
Rate limits and velocity checks
Set thresholds per API key, account, destination and time window to spot unusual request patterns.
02 / Spend protection
Usage and destination rules
Control supported destinations, channel permissions and spend thresholds before traffic escalates.
03 / Accountability
Traceable events
Keep correlated request IDs, provider responses and administrative audit events for investigation.
04 / Safer verification
Time-bound OTP sessions
Apply expiry, attempt limits and replay protections appropriate to the verification flow.
How it works
From one API request to a clear outcome.
Keep your product logic focused on the customer journey. emisiq coordinates the configured communication workflow and returns the events your system needs.
STEP 01
Make a request
Your app requests an OTP or submits an approved transactional notification using the emisiq API.
STEP 02
Apply policy
Validate permissions, templates, limits, channel eligibility and the configured delivery sequence.
STEP 03
Deliver and adapt
Submit through the selected provider and evaluate the delivery events available to decide whether fallback is appropriate.
STEP 04
Return visibility
Send correlated webhook events and make request status, attempts and usage available for reporting.
Designed for developers
Less channel plumbing. More product building.
Use one API-led integration for verification requests, delivery routing and event updates.
One request identityENotifyMe
Correlate requests, attempts and provider events with a traceable identifier.
Webhook-first updates
Receive event updates as delivery progresses.
Clear separation of concerns
Keep verification, notification templates, routing policies and billing records independently manageable.
Developer workflow
One request. A policy-led workflow.
Specify the destination, primary channel and fallback sequence for an authentication request.
