I like MSG91 for its reliable message delivery, which ensures our OTPs and alerts reach users instantly, thus reducing login failures and support tickets. The easy-to-use dashboard makes it simple to track message delivery, manage templates, and analyze reports without requiring technical support, saving time for our operations team. I also appreciate the flexible APIs that help streamline our communication by automating OTPs, notifications, and alerts directly from our system, reducing manual efforts and errors. This makes messaging faster, more reliable, and easier to scale as our communication volume increases. Additionally, the initial setup was fairly straightforward, especially for basic SMS and OTP use cases, as the dashboard and API keys were easy to access. Review collected by and hosted on G2.com.

While MSG91 works reliably overall, the documentation for some advanced features could be more detailed, and the initial setup can feel slightly complex for first-time users. Some of the advanced features like WhatsApp API configuration, template approvals, and detailed reporting could benefit from clearer step-by-step documentation with real use cases.

I use MSG91 for communications, engagement and conversion of my users and prospective users. It helps in increasing my funnel conversion and customer renewal. I like the Campaign and agentic AI workflow features of MSG91. Campaigns have helped me automate most of my customer communications by organizing and scheduling messages efficiently. The Agentic AI workflows in the Hello feature have reduced my customer support tickets significantly by handling most user queries. The initial setup was very easy, and I must complement the MSG91 support team, who was readily available throughout the process, especially Anchal and Nishant.

There are no specific dislikes regarding Msg91’s services. One key suggestion would be to introduce a post-paid billing model, especially for customers in the financial industry where messaging volumes are dynamic in nature. A post-paid model would provide significant relief by eliminating the need to constantly monitor message balances before launching campaigns. Month-end communication is particularly critical in financial services, and any disruption due to balance exhaustion can impact timely customer communication. Additionally, a post-paid model would be operationally easier to manage, as billing would be raised based on actual usage and settled by the customer accordingly, simplifying reconciliation and payment processes.

I appreciate the high SMS delivery rates and the simple MSG91 API integration which reduces time. The OTP and authentication flows are secure, ensuring user verification. Pan-India DLT support is a distinct feature. The implementation is quick, especially for OTP generation and verification. Transactional messaging is almost plug and play, which shortens development and testing time. MSG91 has a robust and developer-friendly API, and the account and API key setup are quick. The clear API documentation, template management workflow, and DLT registration and template setup all contribute to the ease of use. Review collected by and hosted on G2.com.

I find the error messaging clarity lacking. Certain API error responses could be more descriptive, which would help to reduce debugging and tracking. Also, showing delivery success versus cost per template would help retire inefficient templates, potentially reducing costs. Review collected by and hosted on G2.com.

I love the API integration with MSG91. It's very smooth and makes the handling of OTP verifications reliable, providing delivery with speed and consistency. The developer documentation is also very easy to understand, which helps a lot when developing applications for our customers. I really appreciate the responsive support team. They are quick to provide solutions and help customers understand any issues they encounter. MSG91 is also easy and affordable, and they offer startup credits, which are quite beneficial. The initial setup was pretty easy, and I'd rate it four out of five. Review collected by and hosted on G2.com.

I think the startup benefit program needs to be more flexible, and more credits need to be given because some startups take some time to get things working. So it should not be time-bound. Review collected by and hosted on G2.com.

What I like best about MSG91 is its reliability and ease of integration. The APIs are well documented, straightforward to implement, and work smoothly with backend systems, which makes it ideal for developers and growing businesses. Message delivery is fast and consistent, and the delivery reports provide clear visibility into message status.

Another strong point is the flexibility of features. From OTP and transactional SMS to WhatsApp and email APIs, everything is available under one platform, reducing the need to rely on multiple vendors. The dashboard is user friendly, making it easy to manage templates, track usage, and monitor performance.

Customer support is also a big plus. The team is responsive and helpful, especially when dealing with template approvals or integration issues. Overall, MSG91 is a dependable communication platform that scales well with business needs and offers excellent value for money. Review collected by and hosted on G2.com.

While MSG91 is a powerful and reliable platform, there are a few areas that could be improved. At times, template approval and DLT-related processes can feel slow and a bit complex, especially for new users who are not familiar with regulatory requirements. This can delay campaign launches or OTP rollouts.

The dashboard, although feature rich, can sometimes feel overwhelming, and certain settings or reports take extra time to locate. Pricing details and credit usage could also be made more transparent in some cases, particularly when using multiple channels like SMS and WhatsApp together.

Lastly, while customer support is generally helpful, response times can vary during peak hours. Faster, more proactive support for critical or time-sensitive issues would make the overall experience even better. Review collected by and hosted on G2.com.

MSG91 is that the dashboard and documentation can sometimes feel cluttered, which makes it harder to quickly locate specific features or the guidance I need.

I use MSG91 as an SMS gateway for my Shopify app Simplify My Login (https://apps.shopify.com/login-using-otp) to send OTP on SMS and WhatsApp for easy login using mobile number. The platform is very user-friendly, and the APIs are defined for the right standards, making them easy to understand. Support from MSG91, especially Nishant, has been great. He is very responsive and knowledgeable, helping me to get better pricing and quickly solving any issues. The pricing is great, and the platform, along with its support, is best in class. Any issues I have, even on a Friday night, are addressed almost immediately by Nishant with replies within like ten minutes, which has been amazing. I have no reason to switch to another SMS provider. Review collected by and hosted on G2.com.

The SMS capability is already best in class, they can further improve on SMS delivery to countries like Malaysia where none of the SMS gateways provide coverage across all Network providers Review collected by and hosted on G2.com.
