OTP through official WhatsApp, SMS, and email — one interface.
Step 1
Choose the right OTP channel — with confidence
There is no single verification channel that fits every scenario. Some products need SMS, some benefit from official WhatsApp, and some prefer email. What matters is managing those options inside one platform so the operational decision stays clear.

SMS — a direct, fast channel for verification and urgent alert scenarios.
Email — fits flows that need extra documentation or a longer-form record.
Step 2
What Rasel covers inside the verification flow
The platform does more than send the code itself. It helps your team organize templates, channel choice, integration, and delivery follow-up — from first code to final touchpoint.
Templates
Manage WhatsApp templates, service messages, email content, and verification copy in one content workflow.
Integration
Use one API or one operations panel to send OTP and connect it to your applications.
Tracking
Keep delivery status, sending logs, and reporting in the same operating view.
Expansion
Move from OTP into campaigns, conversations, and service messaging without rebuilding your stack.
Turn verification from a blocker into a smooth experience
Start with the channel that fits your audience, then expand into notifications, campaigns, and conversations — from the same platform, without rebuilding your stack.

Step 3
Why OTP belongs inside a broader platform — not a standalone tool
Verification is not isolated from the rest of the journey. Once it lives inside a communication platform, it becomes easier to follow up with service messages, campaigns, or conversations — while reusing the same data.
Send follow-up or notification messages right after verification.
Classify new customers into reusable segments or groups.
Keep channel, status, history, and cost visible in one place.

Frequently asked questions
Can we send OTP through more than one channel in Rasel?
Yes. OTP can run through official WhatsApp, SMS, and email depending on which channels are enabled in your account and how your team wants to operate.
Do we need multiple tools to run OTP?
The idea in Rasel is to reduce operational sprawl and bring verification paths into one platform, with room to expand later into service messaging, conversations, and campaigns.
Are OTP flows tied to templates?
Yes, especially for official WhatsApp and email where templates and structured content play an important role in how messages are organized and approved.
Is Rasel only for verification messages?
No. OTP is one use case inside a broader platform that can later support notifications, campaigns, conversations, scheduled messages, and customer operations.
Run OTP from one platform instead of scattered tools
If your business needs verification over WhatsApp, SMS, or email, start with a platform that gives your team more clarity around channel choice, templates, status, and future expansion.
