Automation Computer Software Used the software for: 1-2 years ### "Saira's review on Twilio" June 19, 2022 5.0 Twilio is the best app for message broadcasting, message scheduling, call recording, data distribution, etc. I personally recommend and suggest my clients and customers use it. Pros Call recording and analyzing agents' performance is the best option that I enjoy while using Twilio. This software is very easy and less expensive to use. As well as we can easily integrate with other web apps to make the workflow more fast, more accurate, and more fluent to enhance our business. Cons The admin interface is a little bit complicated, Twilio should enhance the user experience for admins would be great. Review Source Andrew B. Owner/ Operator Apparel & Fashion Used the software for: 2+ years ### "Can do everything, for all businesses but with a steep learning curve..." August 18, 2023 4.0 Twilio handles all the inbound calls for my website. I ported a vanity 800 number from a another provider to Twilio and after a quite lengthy setup process that involved lots of customer service calls it was up and running. After that you can pretty much leave it or do some minor changes relatively easy. Now when customers call they can choose from an option tree to troubleshoot their issue or they can choose to talk to an agent (me) and if it's during business hours the call gets forwarded to my cell, if outside of business hours they get my voicemail. Works great! I also have it embedded in my website for a chat option that more people actually use. Pros Twilio has every option under the sun, there's nothing call center related that they can't do for you. You could set up automated systems to perform mundane tasks for you, record and inscribe all your calls and even have a call center set up to help troubleshoot issues and direct calls. You can get add-ons from GitHub, integrate into your website especially Shopify and answer calls with a number that you can bring with you or they provide straight to your cell phone. We're talking local numbers and 800 numbers even though you may have to pay extra. Cons Very steep learning curve. There are so many options and so many ways to use this service including third party apps that you could get confused quite easily. Also their 2FA process is tedious which if you're not careful could result in you losing your number.

Plus if your needing to use Twilio on a computer they are the absolute best. And they have a whole marketplace of third party apps that can compliment this service immensely. Switched from [Grasshopper](https://www.capterra.com/p/175002/Grasshopper/) As a student I received a free trial from GitHub and I really liked how many options and integrations Twilio has.

Software Implementation Non-Profit Organization Management Used the software for: 2+ years ### "Purchased out of necessity, expanded due to functionality" January 23, 2023 5.0 I like software that does what it’s supposed to do in the background without requiring regular babysitting. Twilio is exceptionally good at this. As long as our autopay works, the service remains consistently available and functions as expected. Pros For us, the integration is key. We have quite a few non-tech savvy people so operating the backend of Twilio could be intimidating for most of our staff. However, we need a product with extensive features and customization options. Twilio gives us the best of both worlds by integrating our user friendly database with the robust Twilio features. Cons There are always trade offs between available features and ease of use. Sometimes it’s hard to locate a particular setting. However, online documentation has helped me out so far and I have not needed tech support. Reason for choosing Twilio We originally chose Twilio because it already had an API option with our database software. Since that time, other companies have offered us deals but we don’t fix what isn’t broken. The pricing and reliable service keep us a loyal customer. Review Source Ivan S.

February 26, 2023 4.0 Nuestra experiencia general con twillio, es excelente. Lo estamos utilizando desde Wordpress para enviar a nuestros clientes y recibir mensajes de ellos, lo hemos utilizado tambien a su vez para campañas de marketing a traves de sms, la posibilidad de poder enviar mensajes a whatssap es una de las cosas que nos convencio para inclinarnos a utilizar twillio ya que es una de las pocas maneras de las que tienes para enviar mensajes por whatssap de forma automatica. Pros Lo que mas nos ha gustado de twillio ha sido el poder enviar mensajes de texto multimedia, y mensajes de Whatssap desde un mismo lugar.Necesitabamos enviar mensajes por whatssap a nuestros clientes, y nos hablaron de twillio como la mejor plataforma para hacer esto y la verdad es que funciona a la perfeccion. Cons Como unico punto negativo es que al principo puede resultar algo dificil de utilizar, pero una vez que empiezas a trabajar con el y lo controlas un poco, se vuelve mas facil de utilizar. Review Source VR Verified Reviewer IT Manager Retail Used the software for: 1-2 years ### "Twilio's services and tools are reliable, easy to configure, easy to manage, and inexpensive" July 12, 2022 5.0 We use Twilio trunking for our multi-location PBX, and SMS messaging for customer communication. Twilio has worked out very well for us and I would strongly recommend them to other businesses. It's easy to set up, inexpensive and reliable. Pros So far, we use Twilio SMS messaging and SIP trunking. Our experience with was excellent. Everything from creating an account, setting up services, integrating with other systems (PBX and CRM), funding and managing services has been nearly perfect. We did not have a lot of experience with any of these technologies, and we had very little trouble getting it to work the way we want. They have done an outstanding job of designing the services and interfaces so you can put together systems exactly the way you want, without a lot of trouble for spending a lot of money. Cons The one negative that we have encountered so far is that Twilio's SIP trunking does not support T.38 faxing. We do have a couple legacy fax machines set up with ATA's, but they are unreliable both sending and receiving, so we had to supplement this with efax service from another vendor. This setup works, but it would've been nice to have everything together from one vendor. I understand that fax is outdated, but it's still the standard in the medical industry. Reason for choosing Twilio All the other companies were either much more expensive, much more limited in features, or harder to understand and set up. From what I looked at, nothing was even close to Twilio in terms of convenience, features and price. Review Source Sebastian P. Owner Information Technology and Services Used the software for: 2+ years ### "Very useful but getting more and more expensive" June 28, 2023 5.0 You have to build your own interface to use the Twilio API. Or pay for a software that can use the API, which is easier and cheaper. The Twilio interface only allows you to monitor usage, create reports, billing management, and program IVR. It doesn't provide an interface for your sales team to use. Pros I like how complete it is and all the API possibilities. You can achieve so much if you know what you're doing. You can create a call center and monitor everything, including recordings. SMS marketing, ringless voicemail, etc.. Cons As you scale, it gets very expensive (no discounts at all for loyalty). Zapier is losing its market share to Make, Pipedream, and Pabbly. Soon the same will happen to Twilio. Alternatives considered [Vonage Contact Center](https://www.capterra.com/p/104649/ContactWorld/) Reason for choosing Twilio Vonage was much more expensive, and integration with the CRM would have to be built manually. The CRM we chose was already built to integrate with Twilio. Switched from [ActiveCampaign](https://www.capterra.com/p/79367/ActiveCampaign/)[Keap](https://www.capterra.com/p/76390/Infusionsoft/) I found a better CRM that uses the Twilio API to enable VOIP features for the sales team that uses the CRM sales funnel.

February 24, 2023 4.0 Pros Twilio software, including its user-friendly interface, thorough documentation, and adaptable communication features. Twilio's API-centric approach and tools catered to developers are also praised for enabling businesses to personalize and expand their communication channels seamlessly. Moreover, Twilio's dependable service and outstanding customer support are commended by users. Cons Twilio software could be enhanced, such as its pricing model, limited analytics functionalities, and complex configuration process for certain features. Some users have also reported encountering occasional technical problems and errors while using the software. Furthermore, some users have found the learning curve for utilizing the more advanced features of the software to be challenging. Reason for choosing Twilio Twilio is a well-respected communication platform that offers various features and tools to help businesses enhance their customer engagement and communication capabilities. Its API-driven approach and tools for developers make it an appealing option for businesses that want to customize and expand their communication channels effectively. While there are areas where Twilio could improve, such as pricing and analytics capabilities, users generally commend the software's reliable service and outstanding customer support. In summary, Twilio appears to be a valuable asset for businesses aiming to enhance their communication strategies. Review Source Ahmed A.

Pros The most positive aspect of Twilio is its flexibility and scalability, Twilio offers a wide range of communication services, including SMS, voice, video, email, and chat, which can be easily integrated into any application. This allows us to create personalized communication experiences with our customers. Twilio's pay-as-you-go pricing model allows us to scale usage based on our needs, without any long-term contracts or commitments. Twilio's platform also provides a variety of features such as call routing, message personalization, 2-way messaging, contact management, online voice transmission, call monitoring, call recording, MMS, automated responses, reporting and analytics, shortcodes, voicemail transcription, access controls, mobile keywords, call conferencing, SIP trunking and unified communications, all of these features are very useful and make the communication process more efficient and convenient. Cons Twilio is that it may not be as user-friendly as other similar products, You may find the platform complex and difficult to navigate, which could make it challenging for fully utilize all of its features. Even though Twilio's platform offers a wide range of communication services, it may not have some specialized features that other products offer.However, these cons are not unique to Twilio, as any software has its own set of pros and cons.

Nos permite enviar tanto sms como mensajes de whatsapp de forma automatica cuando nuestros clientes hacen una reserva. Pros Lo que mas me ha gustado es que es muy sencilla de utilizar y que nos permite enviar mensajes sms y de whatsapp a nuestros clientes de forma manual o automatica. Nosotros lo utilizamos a traves de WordPress y funciona de maravilla, ademas una de las cosas que me ha gustado bastante es el sistema de respuesta automatica a mensajes. Cons La integracion puede ser un poco complicada, ademas cuando estas empezando tiene tantas opciones que te puede agobiar un poco.Otra cosa que he notado es que la pagina tarda en cargar un poco mas de lo normal.

I was up and running with a programmatic call to Twilio to send text messages from my application within 15 minutes. Twilio Studio and flows provide a great user experience that puts a lot of power into a non-developers hands for managing communication and escalation. Example flows give you just about everything you would need to get started building your own flow. Cons Certain aspects, like accounts, sub-accounts, and management can only be done using the API. These are minor and usually one and done (so they could be done with tool like Postman or SOAPUI).

Managing Director & Software Developer Transportation/Trucking/Railroad Used the software for: 6-12 months ### "Dependable" December 9, 2022 5.0 Overall, however, Twilio is a solid choice for businesses and organizations looking for a comprehensive communications platform. From a developer's perspective, it is one of the simplest solutions to integrate with. Pros Twilio is a powerful and effective communications platform that allows businesses and organizations to easily integrate voice, video, messaging, and other forms of communication into their systems and applications. Some of the key benefits of using Twilio include:Flexibility: Twilio provides a range of different APIs and tools that can be easily integrated into a variety of different platforms and applications. This allows organizations to use Twilio in a way that best fits their needs and requirements.Scalability: Twilio is designed to handle high volumes of traffic, making it a good choice for organizations that need to send or receive large numbers of communications on a regular basis. The service can easily be scaled up or down to meet changing needs.Features: Twilio offers a range of advanced features, including tracking and analytics, voice recognition, and integration with other tools and services. These features can help organizations optimize their communications and improve their overall effectiveness. Cons Despite its many benefits, there are some potential drawbacks to consider when using Twilio.

Additionally, the service may require some technical expertise to set up and use effectively.

Pray you never need their support! I opened a ticket almost a week ago asking for a simple thing: deactivate 2FA to be able to migrate the WhatsApp Business Account (WABA). Until today, they haven't resolved it. They take a long time to respond and send stupid questions. So far, they haven't done what I asked. I'll miss a perfect time to migrate because of them. Pros Telephone number, WhatsApp Sender, and SMS with a good API integration. Cons The support service is terrible. There is no chat support for all customers (you have to pay for this support type in addition to the contracted service). The ticket response time lasts an average of 24 hours. If it's an important issue your company will suffer the consequences. I opened a simple ticket asking to turn off 2FA on my account to migrate the WhatsApp Business Account (WABA). It has been almost a week of messages exchanged and passed from one team to another without any solution to the case. Reason for choosing Twilio They had an integration with WhatsApp Business Account (WABA) compatible with my chat platform and a good integration by API. Review Source NC Nestor C.

Eso si para poder usarla bien, fueron necesarias muchas horas de trabajo y contratar una persona especializada en el tema. Pros Twillio es una plataforma muy potente y robusta, en mi concepto la mejor del mercado. Prácticamente a través de esta plataforma se puede hacer cualquier automatización para envío de SMS, mensajes a través de Whatsapp y telefonía. Cons Lo único que le mejoraría a Twillio es el precio. Para una empresa pequeña creería que es casi imposible de implementar por los costos, además, la configuración requiere de una persona con bastantes conocimientos técnicos, la cual puede llegar a cobrar un buen dineral. Reason for choosing Twilio Twillio es una plataforma muy completa y casi que se puede decir que todo lo encuentras aquí para poder automatizar llamadas telefónicas o envío de mensajes. Es muy completa en verdad. Review Source Lydia L.

Pros Twilio offers all the resources needed to build a complete communication and customer support platform with multiple support channels like video and audio calls and instant messaging. It allows us to collect our customer data and analyze them so as to achieve a better understanding of our customers at a more personal level. Cons Twilio is not an easy to use product and training is always a necessity especially for beginners. Review Source Tanya D. Head Computer Software Used the software for: 2+ years ### "Poor customer service in Twilio" October 6, 2023 3.0 Being one of the major players in the market, Twilio has abused its position greatly! We and our customers consequentially, have experienced major service suspension in our US region. TBy not taking serious operational issues for their customer as a matter of priority they have caused us not only loss of revenue but impacted our reputation vastly. The interruption to services in the US area has been left unresolved for over 2 weeks, being transferred from department to department and mostly handled by AI very unsuccessfully and time consuming.Since it has been a reoccurring issue, and has been solved previously, it shows us that their client data and history management is very poor. Being a global service provider based in the US, they do not take into account the time zone differences and the customer support response time is appalling. The response time window doesn’t consider the time difference when the automation kicks in. Pros The software is easy to use and deploy, fair pricing Cons Level of customer service - our issue with the US carrier is being handled for more than 2 weeks with no success. And Twilio is based in the US.Use of AI in Customer support - no result, tons of disappointment.Kicking the ticket from one department to another knowing the importance of the matter for us and our customers.

CTO Telecommunications Used the software for: 1-2 years ### "Great APIs, terrible customer support and sales" August 21, 2023 4.0 Pros Twilio is generally easy to set up and manage, their APIs are generally well-documented. The developer parts of the company that don't involve human interaction seem to be good. It is the backbone of a lot of our core company infrastructure. Cons The (now terminated) salesperson we originally worked with was very helpful at the beginning and even roped in engineers to have discussions with us. They poorly explained the contract and even made promises that were not true. After we inked a volume deal with them, the support from sales became practically non-existent. The salesperson locked us into a contract.We were able to get a refund and have the contract terminated, although the refund process took months and lots of book and forth.

Twilio delivers messages fast and reliable all around the globe for a very competitive price. It usually takes just a few seconds to deliver the message. With Twilio, you don't even need to buy a phone number since you can send messages from an alphanumeric ID. You just need to make sure that this is legal in your country and take an additional registration step if required by law. Choosing the phone number from which you will send a message is sometimes a better solution since you can then also receive messages and for example, receive messages for unsubscribing the customer from your SMS marketing platform. What I particularly like about Twilio is their offer for Non Profit organizations. They are willing to credit your account with 500$ if you are a registered Non-Profit and that is amazing! I don't know of any other company that gives such big credits for free and that speaks that company is led by managers who certainly have a great vision which is not only to make a profit but help people by providing easy use service. Their API is amazing! Documentation is full of examples and a lot of programming languages are supported out of the box. Their API services are not just developer focussed and overall complete service is so easy to use that I don't know why I haven't been using it much before. Cons Twilio dashboard is not the best experience and I don't like it even though it received a redesign recently. It feels kinda outdated and it isn't optimized for mobile devices what I found kinda alerting for 2022. Although you won't be using it on your mobile phone primarily, it is nice if you could check the error log fast on the go if a lot of them start popping out and alerting you on channels you set.

Partner Logistics and Supply Chain Used the software for: 2+ years ### "Twilio is great, but the learning curve is greater" June 7, 2022 5.0 Because I don't make any changes to Twilio on my own, the barrier to entry requires me to rely on third-party developers to fulfill all my requests due to my technological limitations. While this could be considered a good thing, as most business owners should not be screwing around with their phone system, it does mean that I need to be reliant on a third party to help make the Twilio implementation I dream up. When everything is set up correctly, I never have issues with Twilio. That level of reliability means a lot when it comes to a business phone system. Because of this, I wholeheartedly recommend Twilio to any business. Just be prepared to take a deep dive into the learning curve or hire a third party. Pros Twilio has set the bar pretty high with the customizability of telephony. You can do incredible things with Twilio. From a simple phone tree to complex actions that integrate other applications with the likes of Zapier and other no-code services, the sky is the limit for most small business owners to create great solutions. Cons The downside is the learning curve. In comparison, I consider myself tutorial literate when coding and setting systems up. I can't seem the find the ability to build proficiency in Twilio. And while this is my own doing, it is my only con. Twilio is incredible. For whatever reason, I have difficulty handling the tweaking on my own.

Cons They have some limitations when it comes to the WhatsApp API. A lot of bureaucracy and long wait times are not suitable for businesses looking for a solution.

It is so flexible, Although it has been a little bit complicated sometimes to self-learn about online phoning systems it saved me from a lot of hassles I wanted to avoid. The best benefit you get is the ultra efficient support service Pros With Twilio you can start from scratch to build your own online communication system. I didn't know so much about VOIP before and it is true I had to learn a few things. So far I have been able to use my Twilio french mobile number fully online even whenI need to travel abroad - with all mobile services you can expect (voice, SMS, MMS). The pricing is light and the global user interface makes the whole systme pretty easy to manage. I only use a few features from the platform but the possibilities are huge ! And they are always working on new services. And as Twilio is now really recognized as a communication company you can find additional software apps very easily and even documentation, I am thinking of the softphone app I am using on my mobile or desktop for instance. Cons I could customize a personal solution because I had time to test different options and as a developer I could code stuffs if needed. I am not sure everybody can do the same without technical skills.

When I contacted customer support they told me that it was because Twilio no longer offered email verification for free users. Well, they could have at least sent an email out telling everyone that. I would be forced to buy their tiered plan, switch services, or set up my own verification which sucks but at least tell your users that you're making these changes right? Pros It had a high number of emails you could send for free every day Cons They had a sprawling system that required like four api keys just to set up and integration between multiple products with little to no to innacurate documentation. First you have to have a SendGrid account and set up an API Key (first key in .env) , then you have to make an email template which is very hard to do because they have a lot of bugs with that whole system and its rather confusing as well, especially in regards to trying to actually write your own code for how it looks . Then you go to Twilio and get your Auth Token (second .env) and create a Service that has its own token (third .env) , then you integrate that with your sendGrid Template and I forgot where exatly but there some fourth token you need. It's ridiculously complicated and poorly set up, and the documentation doesn't really tell you how to code it, the page that tells you how to send emails has code examples for sending text messages so that's unhelpful. It took me several hours to figure out how it all works and get it set up for automatic emailing. When I switched to Courier it took my literally 15 minutes to do the exact same thing. They had great documentation, a wonderful easy to use website, and just one API key. Don't use Twilio, it's trash, try Courier. Reason for choosing Twilio I know Twilio uses SendGrid for their email automation but I really like their email verification service so I used Twilio rather than straight up SendGrid. SendGrid I have no problem with, they are decent enough Review Source Talk to a Capterra advisor for free and get results within 15 minutes.
