Overall Satisfaction with Twilio

We were working on a client project where we have to develop a global application which will be available throughout the world. App has an authentication system where we send sms, email or use whatsapp. We needed a single partner where API integrations would be seamless and fast. Also we don't want to deal with lots of configurations for countries and twilio was the one of best provider for us.

Pros

  • Great authentication system for OTP auth via sms, email
  • Well documented apis.
  • AI bug fixing you just needs to go to your error and AI will help you to solutions.

Cons

  • Would be happy if they upload some youtube videos for navigating and guiding for particular solutions like sms otp. After going through lots of doc we discovered this
  • AI solution agent is good for knowing the reason of error in logs but sometimes we need like connecting to their agent.
  • Whatsapp automation is great but need more features like where we can create proper chatbot with drag and drop
  • Customer satisfaction was increased as now the sms were getting delivered all over the world.
  • The whatsapp integration was seamless and very cost effective for us compared to other vendors.
  • Reduced back and forth as the API integration documents are pretty easy.
  • We need to do registration for carrier id for every country but its very simple process with Twilio
We use multiple channels . We use sms for transactional and also for authentication otp. We use whatsapp for interacting with user, where we used that as our customer service agent. And we use Email channel for onboarding emails and alerting emails. We got all the channels we required in twilio. Just for email we registered with sendgrid account also.
For developing a notification system its required to integrate certain apis for different vendors. With Twilio it was seamless as all the required channels were available at single platform. And other vendors takes time to deliver when the traffic is at peak but Twilios performance was at par even if its a peak. So we don't have to implement another solution for retry loops or scaling as Twilio is scaled for this.
Twilio is very reliable in terms of performance. We had faced issues with past vendors on non-delivery and then how to check the logs finding the issues. But with Twilio they have good monitoring , logging and metrics for all of the channels which makes it easy to debug any issues arise. And the AI support system is just great it helps a lot in debugging and knowing the root cause of problem.
Some of the products we used were MSG91 and SMSala but the issue with them we got to know after the integrations that at some part of the world these integrations are not able to deliver important OTP sms and also it was hard to find solutions in their site. Then we switched to Twilio and got to know about the process of registration and approval we need to take from country for our carrier id. So Twilio became best choice for us.

Do you think Twilio delivers good value for the price?

Yes

Are you happy with Twilio's feature set?

Yes

Did Twilio live up to sales and marketing promises?

Yes

Did implementation of Twilio go as expected?

Yes

Would you buy Twilio again?

Yes

You want a single solution for authentication also and delivering transactional notifications to your users globally, then twilio is anyday best solution. Just do whatsapp integrations, sms, or email with same api and it reduce the code also. The monitoring in twilio is also great you can always see what notifications you sent and which are delivered.

Evaluating Twilio and Competitors

Yes - We were using multiple products earlier for different channels. For email we were using bravo which got replaced with twilio's email sendgrid apis. Then we were using SMSala and MSG91 which later on replaced for OTP authorisation and transactional sms to Twilio because of better support and simpler API integration. Also we added whatsapp support with Twilio
  • Cloud Solutions
  • Scalability
  • Integration with Other Systems
  • Ease of Use
- Easy integration and Reliability.
Earlier with our integrations we faced some difficulties with most of platform in identifying the issues with the integration or may be API payloads. But in Twilio we found the support system was great and the error tracking was easier. The monitoring solution for all the email, sms and other channels was easier to track on dashboards and debug the issues with AI.
With all the exposure to API's and integrations it would be now a lot more easier and faster for us to add communication and notification channels in any new project with Twilio. Without any single thought we will go with Twilio, as we don't want to be in a situation to again analyse different tools and then come up with solution to use Twilio.
