In today's digital world, verifying users and transactions through OTP SMS has become a common practice. However, the way OTP messages are crafted can significantly impact the user experience and the success of customer onboarding. By prioritizing customer empathy in the crafting of OTP messages, businesses can make the user's journey smoother and more seamless.

Importance of Customer Onboarding

76% of customers are likely to stay with a service after a welcoming onboarding experience. Customer onboarding is a critical process in marketing that can make or break a business. It not only increases revenue but also helps build relationships with customers. The onboarding process begins when a customer decides to pay for a product or service, but it doesn't end there. It continues until the customer becomes a regular patron of the business. Successful onboarding involves repeat sales and customer retention over a period.

Crafting OTP Messages for a Seamless User Experience

When it comes to crafting OTP messages, the position of the most important information, such as the OTP itself, plays a crucial role in the user's journey. The speed at which the OTP is delivered by OTP service provider and the way the OTP message is presented can either make the user's experience seamless or introduce unnecessary friction.

For example, let's consider two different OTP message formats:

OTP Message 1:

Dear User, Your OTP is: 123456. Please use this OTP to complete your transaction.

OTP Message 2:

Dear User, To complete your transaction, please enter the OTP: 123456.  

At first glance, these messages may seem quite similar. However, the positioning of the OTP information differs, which can impact the user experience.

In the case of desktop transactions, where the user is transacting with the brand on a computer, the friction in the user journey may be minimal. The user can easily view the OTP message and interact with the brand's digital interface simultaneously. However, the story is different for mobile transactions, especially in a mobile-first market like India.

In the mobile scenario, users typically receive a notification with the OTP message. If the OTP message is crafted as an example 1, the most important information (the OTP) is easily visible through the notification itself. This eliminates the need for the user to open the SMS app separately, reducing additional steps in the process.

On the other hand, if the OTP SMS is crafted as an example 2, the user may have to switch to the SMS app, copy the OTP, and then paste it into the brand's digital interface. This three-step process can be time-consuming and may result in the user losing their current session, leading to frustration.

Impact on Business KPIs

While there may not be specific data to validate the impact of OTP message crafting on business Key Performance Indicators (KPIs), it is reasonable to assume that if the transaction is related to important business metrics such as product sales or user onboarding, poor OTP message design can lead to a reduction in conversion rates.

In the world of hyper-competitiveness, many brands may overlook the opportunity to engage users at the micro-transaction level. However, by prioritizing customer empathy and optimizing the crafting of OTP messages, brands can not only improve the user experience but also achieve consistent brand recall.

Best Practices for OTP Message Crafting

To master customer onboarding with OTP SMS, businesses can follow these best practices:

  1. Keep the most important information upfront: Place the OTP information at the beginning of the message, making it easily visible to users.
  2. Use clear and concise language: Craft OTP messages using simple and straightforward language to ensure that users can understand and act upon the information quickly.
  3. Consider the user's context: Understand the user's journey and the device they are using to optimize the OTP message format accordingly. For mobile transactions, prioritize displaying the OTP in notifications to minimize user effort.
  4. Provide clear instructions: Clearly outline how the OTP should be used and what action the user needs to take to complete the transaction.
  5. Ensure consistency across channels: Maintain consistency in the format and tone of OTP messages across different channels (SMS, email, push notifications, etc.) to provide a seamless user experience.
  6. Continuously test and optimize: Regularly analyze user feedback and data to identify areas for improvement in OTP message design and optimize the onboarding process.

Conclusion

Crafting OTP messages with customer empathy in mind is crucial for mastering customer onboarding. By considering the user's context, providing clear instructions, and optimizing the format and positioning of the OTP information, businesses can create a seamless user experience and increase conversion rates. Remember to continuously test and optimize the OTP message design to ensure the best possible onboarding process for your customers.

Frequently Asked Questions

How do I choose the right OTP service provider?

When selecting an OTP SMS service provider, focus on:

  • Delivery reliability and speed
  • Global coverage and local compliance
  • Multi-channel support and fallback
  • Ease of integration
  • Pricing transparency

The right provider should not just send OTPs but ensure they are delivered consistently across regions and networks.

Not all OTP SMS service providers are built the same.

Some optimize for cost, others for flexibility but very few balance delivery reliability, global coverage and ease of use. And that balance is what actually impacts whether your users receive OTPs on time.

If OTP is critical to your product, focus on:

  • reliable delivery (not just sending)
  • multi-channel fallback
  • scalability across regions

Try It for Yourself

Why is multi-channel OTP important?

Relying only on SMS can lead to failed verifications due to:

  • network issues
  • telecom filtering
  • device limitations

Multi-channel OTP systems (SMS + WhatsApp + voice) improve success rates by automatically retrying through alternative channels if one fails.

What is the best OTP SMS service provider in India?

Some of the commonly used OTP SMS service providers in India include MSG91, Exotel and 2Factor.

That said, India has additional challenges like DLT compliance and operator filtering. Platforms that handle these internally while also offering fallback options tend to provide more consistent OTP delivery.

Which is the cheapest OTP service provider?

Providers like Fast2SMS and 2Factor are often considered among the cheapest OTP service providers, especially in India.

However, lower pricing can come with trade-offs such as:

  • lower route quality
  • higher delivery delays
  • limited fallback options

For mission-critical OTP flows, reliability often matters more than just cost.

Which is the best OTP service provider in 2026?

The best OTP service provider depends on your use case.

  • For global scale and flexibility: Twilio, Infobip
  • For cost-effective APIs: Plivo
  • For India-focused SMS OTP: MSG91, Exotel

However, platforms like Message Central stand out by balancing global coverage, multi-channel fallback and ease of deployment, making them suitable for businesses that prioritize delivery reliability.

What is an OTP service provider?

An OTP service provider enables businesses to send temporary verification codes to users via channels like SMS, WhatsApp or voice to authenticate logins, transactions or sign-ups.

Modern OTP SMS service providers go beyond just sending messages, they ensure reliable delivery using optimized routing, retries and sometimes multi-channel fallback.
