MSG91 Delivers Fast, Reliable OTPs with a Handy Flow Builder **Rating:** 4.5/5.0 stars **Reviewed by:** Steve M. | IT Services Consultant, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** April 30, 2026 **What do you like best about MSG91?** We use MSG91 across multiple client projects at Ntiva, mainly for OTP authentication, transactional alerts, and WhatsApp notifications. The UI is fairly clean and easy to navigate once you get familiar with it. The Flow Builder is especially useful — it allows us to design automation visually instead of relying only on code. In terms of integrations, connecting MSG91 with our internal systems and CRM tools was straightforward using APIs. The documentation is helpful, and most integrations work smoothly without major issues. Performance-wise, message delivery is fast and reliable. OTPs are delivered within seconds, which is critical for user authentication flows. We also noticed stable uptime during high traffic periods. Pricing is reasonable compared to other messaging providers. The ROI is clear for us because it reduces manual communication effort and improves customer response time. **What do you dislike about MSG91?** Some parts of the dashboard can feel slightly confusing for new users, especially when configuring flows or templates for the first time. The onboarding process could be more guided with step-by-step tutorials. Also, while support is responsive, complex issues sometimes take time to resolve. More detailed error logs would make troubleshooting easier. **What problems is MSG91 solving and how is that benefiting you?** Before using MSG91, we relied on manual messaging processes and basic scripts for notifications. Now, everything is centralized and automated. We use it for: OTP verification for secure login Automated SMS alerts for system events WhatsApp notifications for client communication This has significantly reduced manual workload and improved operational efficiency. Customers now receive real-time updates without delays, which improves overall user experience. Additionally, MSG91’s automation and basic AI-driven optimizations (like smart routing and delivery handling) help ensure better delivery rates and campaign performance. I personally use MSG91 in my daily workflow to manage communication automation for multiple client environments, especially focusing on authentication flows and real-time notification delivery. ### 2. Reliable, Fast SMS Automation for Order Updates and OTPs **Rating:** 5.0/5.0 stars **Reviewed by:** Jerry D. | Director of Business Development, Telecommunications, Small-Business (50 or fewer emp.) **Reviewed Date:** April 22, 2026 **What do you like best about MSG91?** We started using MSG91 in one of our eCommerce projects where we needed to send order updates and OTP verification messages to customers. Since we manage multiple Shopify-based stores at Velstar, having a reliable SMS solution is important for our operations. From a UI/UX perspective, the platform is clean but takes some time to understand initially, especially while working with templates and flow setup. Once familiar, the flow builder becomes useful for building simple automation without much engineering effort. In terms of integrations, MSG91 works well with our backend systems through APIs and was relatively easy to connect with our existing setup. Performance has been consistent, and delivery speed is generally fast, which is critical for OTPs and order notifications. Pricing also felt reasonable compared to other providers we evaluated, and it provided good ROI since we use it across multiple client stores without significant cost overhead. **What do you dislike about MSG91?** The onboarding experience could be improved for new users. Some parts of the dashboard are not very intuitive at first, and understanding template setup requires trial and error. Support is helpful, but response time can sometimes vary depending on the issue. Also, the system does not provide much AI-driven intelligence or smart insights, such as delivery optimization or engagement analytics, which could make the platform more advanced. When errors happen in a flow, the debugging information is not always detailed enough, so troubleshooting takes additional time. **What problems is MSG91 solving and how is that benefiting you?** MSG91 helps us automate OTP verification and order-related SMS notifications across our eCommerce operations. Earlier, these communications required manual handling or separate scripts, which was inefficient. Now everything is more structured and automated, which improves reliability and reduces manual effort. Customers receive updates instantly, and our team can focus more on core product and operations work instead of managing communication workflows. Overall, it has improved operational efficiency and provided a stable communication layer for our Shopify-based systems. ### 3. Reliable, Cost-Effective Messaging with a Clean UI and Handy Flow Builder **Rating:** 5.0/5.0 stars **Reviewed by:** Guido C. | Chief Technology Officer, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** April 23, 2026 **What do you like best about MSG91?** As a Chief Technology Officer at Tablevibe, we use MSG91 mainly for sending OTPs, order confirmations, and occasional campaign alerts across our few partner restaurants. From a UI/UX perspective, the platform is fairly clean and structured once you get familiar with it. The flow builder is especially useful for setting up simple automation like order status updates without needing heavy development work. In terms of integrations, we connected MSG91 with our backend ordering system via APIs, and it has been flexible enough to handle our use case. Performance has been reliable—message delivery is generally fast, which is critical for OTP verification and real-time order communication. Another thing worth mentioning is the pricing. Compared to some alternatives we evaluated, MSG91 offered a more cost-effective setup for transactional messaging, which made the ROI reasonable for scaling across multiple restaurant clients. **What do you dislike about MSG91?** The initial onboarding experience could be smoother, especially for non-technical users. Some parts of the dashboard are not very intuitive at first, and template configuration requires a bit of trial and error. Also, when something fails in a flow, the error logs are not always detailed enough, which slows down troubleshooting. From an intelligence standpoint, it would be helpful if MSG91 offered more built-in analytics or AI-driven suggestions (like delivery optimization or engagement insights) instead of relying mostly on basic reporting. **What problems is MSG91 solving and how is that benefiting you?** MSG91 helps us automate critical communication like OTP verification and order notifications, which are essential in a restaurant ordering environment. Before implementing it, some of these processes required manual intervention or less reliable systems. Now, everything is more streamlined—customers receive instant updates, and our partners don’t need to worry about missed communications. This has improved operational efficiency and reduced support overhead. Overall, it plays a key role in ensuring smooth communication between our platform and end users. ### 4. Fast OTP Delivery and Easy MSG91 Integration **Rating:** 5.0/5.0 stars **Reviewed by:** Connor K. | Senior DevOps Engineer, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** April 21, 2026 **What do you like best about MSG91?** Our software product uses MSG91 for login verification and alerts. What we found most beneficial is the speedy delivery of OTP, which makes the login process more seamless. We found the integration aspect to be appealing as well. The initial setup was completed reading the documentation which does not take much time as connecting SMS API from the backend was easy. When we manage backend with Supabase then we did not face any major issues adding MSG91 here. Furthermore, you can monitor which OTPs have failed or been sent, which is useful for troubleshooting – another good feature. **What do you dislike about MSG91?** The dashboard UI is not very friendly. Looking for some things takes a while, especially in the reporting section. Although the delivery is mostly on time, there are delays that you will notice while doing OTP verification. In fact, they haven't always responded right away. In some cases, I have had to follow up. The pricing structure is easy to understand, but the cost rises sharply with usage which makes long-term forecasting somewhat precarious. **What problems is MSG91 solving and how is that benefiting you?** Earlier, we tried administering the OTP on our own which resulted in inconsistent delivery and issues with gateway handling. Since we have started using MSG91, we never had to worry about external SMS infrastructure anymore We merely utilize API calls, and they carry out the OTP. The system undergoes a significant reduction in the development effort and is easy-top-maintain. The user verification mechanism has stabilized, as failure rates have decreased. It’s always reliable but may have some delays. ### 5. Fast, Reliable OTP Delivery with Smooth Shopify and Zoho CRM Integrations **Rating:** 5.0/5.0 stars **Reviewed by:** Eunice O. | Global Senior Customer Experience Manager, Marketing and Advertising, Mid-Market (51-1000 emp.) **Reviewed Date:** April 19, 2026 **What do you like best about MSG91?** I work for a medium-sized e-commerce business (team of around 51–200 people), and we mainly use MSG91 for OTPs and order updates. What I liked most was the speed of OTP delivery most of the time, it reaches users within 2–3 seconds. This means there are no hassles with the login or verification process. The dashboard isn't very complicated; even new users can quickly get to grips with it. We integrated with Shopify and Zoho CRM both integrations went very smoothly. Our developer didn't need much time to set up the API. Once, during one of our sales, traffic suddenly increased, but message delivery remained stable. This was important to us because, at that time, if the OTP failed, the conversion rate would have dropped. **What do you dislike about MSG91?** Although everything is generally working well, there are still some issues in certain areas. Occasionally, OTPs are delayed for some numbers, especially in remote areas. Although it's not a huge issue, it is noticeable. Another thing is that some of the reporting options on the dashboard seem a bit basic, if you want to carry out a detailed analysis, you have to export the data and view it separately. Support is generally fine, but it takes a bit longer to get a response at peak times. I think it would be good if the support team's response time was a bit faster. **What problems is MSG91 solving and how is that benefiting you?** We used to have problems with OTP delivery; the codes would often arrive late or fail to arrive. We can now send OTPs quickly using MSG91, which has made the user login and order confirmation processes much smoother. As a result, the pressure on our customer support team has decreased, and our conversion rate has also increased slightly. ### 6. Smooth API Integration and Centralized OTP & SMS Messaging with Fast Deliveries **Rating:** 5.0/5.0 stars **Reviewed by:** Shauna Z. | Product Manager, Computer Software, Mid-Market (51-1000 emp.) **Reviewed Date:** April 18, 2026 **What do you like best about MSG91?** We mainly use MSG91 for order updates, OTP verification and customer notifications. What we found most helpful was being able to manage multiple communications from one place - both OTPs and transactional SMS messages. This means we don't have to maintain separate services. The API integration process was smooth for us. The development team managed to set up the basic flow in a very short time. In particular, it has become easy to trigger order confirmation SMS messages. Another positive aspect is that deliveries are fast most of the time - customers receive updates quickly, which has led to a slight reduction in support queries. You can track issues by checking the logs on the dashboard, which is useful in practice. **What do you dislike about MSG91?** The user interface of the dashboard is not fully intuitive. Finding some options can take some time especially the first time around. The reporting section must be focused clarity. The delivery will not miss an OTP or notification that needs to be delivered urgently. Although, at times the delivery is getting delayed in most of the cases it’s good. At first the pricing was something we could manage. But as we started using it more and more we found it becoming expensive. The support team is helpful, but not always on time. I had to follow up on several occasions. **What problems is MSG91 solving and how is that benefiting you?** In the past, we used separate tools for notifications and OTPs, which was difficult to maintain. We had separate integrations and separate tracking - overall, it was very complex. Since we started using MSG91, we have been able to manage all our communications from one place. As a result, the backend has become simpler and maintenance work has been reduced. The order notification flow has improved - customers are receiving updates more quickly, which means we are receiving fewer queries about 'order status'. Although there are occasional delays, the overall process is now more organised than before. ### 7. Fast OTP Delivery and Easy API Integration with MSG91 **Rating:** 5.0/5.0 stars **Reviewed by:** Alex A. | Senior Product Manager, Market Research, Mid-Market (51-1000 emp.) **Reviewed Date:** April 17, 2026 **What do you like best about MSG91?** We use MSG91 within our SaaS app for user verification and system notifications. What I like the most is the OTP delivery speed. Most of the time the users get the OTP within a few seconds. This helps to keep the onboarding flow smooth. Integrating the API was easy. The SMS API setup was done in no time by our development team and the documentation is clear. You can look at the logs that show the SMS sent and failed from the dashboard. Moreover, in addition to OTPs, we can also send transactional alerts (like account updates or payment confirmations) from the same platform, which has multi-use support. This means you will not even need to use a different tool, thus simplifying the workflow. **What do you dislike about MSG91?** At first, I found the dashboard to be very annoying. The interface is filled with many options but I do not need to select all options. The organisation in the reporting section should be a bit more clear and more organised. Generally speaking, it is quick but may have delays. Messages may not reach the delivery channel (user’s mobile) which hampering OTP flow. User is unhappy and said code delivery was late. In the beginning, it was affordable but after that, the price skyrockets as the long term planning doesn’t get easy when gets breakdown. The feedback you get may not be fast. You may occasionally have to follow up. **What problems is MSG91 solving and how is that benefiting you?** Previously, we used separate services for OTPs and notifications, which was cumbersome to manage. Maintaining integrations and tracking delivery - everything had to be done in different places. Since using MSG91, we've been able to manage OTPs and transactional SMS from a single platform. This has simplified our backend and reduced maintenance. In particular, there's been an improvement in the user verification flow. There used to be more delays and failures; now the success rate is comparatively better. This has slightly increased the sign-up completion rate. However, not everything is perfect-delivery delays mean we still need to have a fallback for critical cases. Even so, overall it has made our communication process much more organised. ### 8. MSG91 Streamlines Automated SMS Notifications with an Intuitive Interface **Rating:** 5.0/5.0 stars **Reviewed by:** Harry S. | Information Technology Consultant, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** April 16, 2026 **What do you like best about MSG91?** We recently started implementing MSG91 at BairesDev to improve communication workflows across our development and support teams. The platform is very useful for setting up automated SMS notifications for system alerts and project updates. The interface is intuitive, and the ability to integrate messaging with our internal tools makes it easier to manage communication at scale. We also find the automation features helpful for reducing manual effort and ensuring timely notifications. **What do you dislike about MSG91?** Since we are still in the implementation phase, some advanced features require additional configuration and technical understanding. More detailed documentation and onboarding support would make the setup process faster. **What problems is MSG91 solving and how is that benefiting you?** MSG91 helps us automate communication between teams and systems, especially for alerts and operational updates. This reduces manual messaging, improves response time, and ensures consistent communication across projects. It is helping us streamline workflows and improve overall operational efficiency. **Official Response from Ragini Pawar:** > Hi Harry, Thanks for sharing this, especially while you’re still setting things up.

MSG91 Makes SMS Templates and Automated Alerts Simple **Rating:** 5.0/5.0 stars **Reviewed by:** Alesya B. | Operations Specialist, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** April 09, 2026 **What do you like best about MSG91?** We recently started implementing MSG91 at Belitsoft Software Development Company to improve our operational communication and notification workflows. The platform makes it easy to create SMS templates and automate alerts for system updates and customer notifications. The UI is simple and easy to navigate, and template management helps us standardize communication across teams. We also appreciate the integration capabilities, which allow us to connect messaging workflows with our internal applications. **What do you dislike about MSG91?** Since we are still implementing MSG91, some advanced configuration options require time to understand.

Reliable, Fast SMS Delivery with Transparent, Reasonable Pricing **Rating:** 5.0/5.0 stars **Reviewed by:** Abhinav M. | SDE Intern, Small-Business (50 or fewer emp.) **Reviewed Date:** January 27, 2026 **What do you like best about MSG91?** MSG91 is easy to implement and integrate with our scheduling system. Pricing is affordable and transparent, which makes cost management straightforward. SMS delivery is reliable and messages usually reach users on time, which is important for reminder notifications. The platform is simple to use on a daily basis. Customer support has been great overall. Karan was very responsive and helpful whenever we needed assistance. **What do you dislike about MSG91?** Sometimes webhooks do not get delivered properly, and in a few cases it is not very clear why an SMS failed. The error details could be more descriptive. That said, some of these issues can also be due to carrier-side problems, so it is not always in MSG91’s control. **What problems is MSG91 solving and how is that benefiting you?** MSG91 helps us reliably send SMS reminders to users for scheduled bookings. It solves the problem of timely user notifications without adding complexity on the implementation side. Because delivery is reliable and pricing is transparent, we can run reminder workflows daily without worrying about failures or unexpected costs. **Official Response from Ragini Pawar:** > Hi Abhinav!
