In general, terms Twilio is a good application for creating a message processing network, where APIs are used to achieve specialized results depending on your HTTP needs, such as custom messages if you are working with a specific application that requires reminders or event schedule.
  • Twilio helps us to maintain stable connections not only at the level of [customization] but also allows us to create a fully automated and specialized workforce in this area.
  • it basically creates a global communication network based on telephony protocols, to keep costs low while covering the entire workforce.
  • Twilio relies too much on HTTP methodology to work, so if there is a problem with our private network servers, we would be completely exposed.
  • If we are working with events of a specific nature, Twilio takes a long time to define the messaging URLs we are working with, which slows things down a bit.
Twilio is a simple service that serves as an excellent starting point to create a suitable bridge between an internet network and a telephone network so that we can achieve a high level of group connectivity where interactions are always the most important thing, and it remains cost-effective for the whole team.
The customer service is impressive, we only had one hiccup at the beginning with the HTTP configuration but we were able to synchronize the server almost immediately.
Thanks to Twilio we were able to keep all our connections with the workforce active in a fast and reliable way based on a communication network while spending as little working time as possible.

I use Twilio to create custom chat messages on Facebook. And it has been A great help! I am not always able to answer chat messages immediately when they come in, so having Twilio helps gather important information from a customer and sometimes can help the customer with simple questions like locations, hours of operation. Setting up the chatbot is super easy, and customer support is very helpful.
  • Gathers information from the client’s interactions
  • Can help answer pre-programmable queations
  • Provides peace of mind that you aren't missing chat messages
  • I haven't had any issues with Twilio
If you have a business page on Facebook, having Twilio’s chat not feature is a must! No more missed chat messages or clients getting upset because of a delay in replies. Twilio has helped on several occasions answer simple questions, so I didn't even have to answer the chat message manually. It also enables you to recognize when spammy messages are trying to get through.

Given the amount of tools for voice recognition or report management, we recognize that Twilio is one of the best services oriented towards support operations and communication management that we will be able to find throughout our business life. We are satisfied and pleased to be using Twilio to cover our communication.
  • Twilio's API is so easy to program that we can create a complete network of calls routed and connected to each other in the most complex way possible, where all kinds of operations are applied, from screening to call transcription processes.
  • Its communication system takes omnichannel mechanics from other services and optimizes them, making communication very extensible.
  • There are several shortcomings within the Twilio platform, mostly in the area of real-time monitoring management, since Twilio does not have advanced tracking tools to keep smoothly auditing operations that need to be performed.
  • It does not have a programmable alert system, which forces us to depend on another service to manage the alerts in case of relevant calls at a certain time.
We recommend working with Twilio to keep statistical control of everything that keeps happening within our web marketing processes. Twilio is very useful in the application of attribute-based routing thanks to its high level of data filtering and artificial intelligence tools, which can also be customized.
Although we haven't had any major issues, we know that customer service is fast enough to make up for the errors that Twilio can make.
Twilio has been very helpful thanks to its omnichannel communication system, it has helped us to optimize communication and its use is extensible through a well configured API.

In a world dominated by emails, we found that SMS notifications have a much higher chance of being read and actioned. We use Twilio to SMS our clients when they have new agreements to attend to, we use it to notify them of important deadlines as well as to provide a satisfaction survey where they simply have to reply with a numeric value. Due to the engagement rate being higher than that of email we were able to improve our processes based on feedback received and we were able to improve customer experience by keeping them up to date.
  • SMS
  • Custom Numbers
  • Integration to 3rd Parties
  • Perhaps a lite version of their web interface for new users
When you want to build your own workflows that require communication via SMS. Twilio literally integrates with everything and you don't need to purchase bespoke solutions
Whenever an issue has occurred their support has been super fast and efficient to resolve
If you don't have a little bit of tech-savviness you might become overwhelmed with their web interface

We use the Twilio integration to use Twilio in Microsoft's Dynamics 365. This integration lets our customers use SMS as another marketing feature our clients can use within Dynamics CRM. With Twilio, they can send individual or bulk SMS messages to their Leads and Contacts in Dynamics CRM. It is a simple and great feature!
  • Simplicity
  • Fast
  • Massive
  • Perhaps the error logging could improve -- it is sometimes a bit vague
I think it is well suited for massive bulks sends. I honestly cannot think of a better option, even for individual sends. The features it brings are simple and easy to use. I have nothing to complain about Twilio other than perhaps their portal and language can be a bit confusing

In our sales department, as well as Account Management we utilize the Twilio text reminder service in conjunction with our CRM to send prospective and current customers text messages. This has eliminated a lot of ghost calls and missed communication with our potential customers, and current. Most clinicians are busy throughout their day in session so being able to text back and forth is much easier. We've closed a lot more sales from having better communication! Twilio works like a charm!
  • Integrates well with other platforms
  • Easy to setup
  • Support is good
  • The application for mobile phones
  • Adding a feature where you can lookup numbers to see if they're a landline or cell
  • More mobile friendly use
Using the texting capabilities that Twilio has provided within the CRM system my company uses it has allowed me to gain more sales and better communication with my prospective customers. As we all know - time is money, so being able to save time and communicate clearly is a huge help with my job.

I work with busy clinicians all day and they're usually in session but need to communicate quickly to get questions and concerns answered. I am able to quickly respond to them via text and send them important information that they have at their fingertips. I can also send out auto-texts to new clients so they're being taken care of right away.

We use Twilio to buy or purchase our customer's phone numbers that they were going to use once we set up their SevenRooms account.
  • They provide you all the numbers that were available in a certain country.
  • Their security is very very tight for their customers.
  • Very easy to use and navigate,
  • Lags on their website.
  • Long time to load a certain page.
Well, for me personally, as a Data Entry Specialist, I find Twilio a very handy and useful tool for my work. You can set up your customer's phone number very easily. But, the only downside is there's a lot of unsupported countries on Twilio's network. I wish they would be able to support every country that needs a Twilio setup.

We use Twilio as part of our email campaigns with sendgrid. If a recipient from one of our emails engages with our email (open or click depending on the campaign) we initiate an SMS follow-up message. We can take some of the custom data points we use in the email campaign like name, company name, city, state, etc, and use [them] in the SMS message.
  • SMS text messaging
  • incorporate multiple channels into a marketing campaign
  • Broaden customer engagement
  • Better dashboard/reporting
  • Incorporate more channels like social media, direct mail, etc
  • Pricing is fair but I'm seeing alternatives pop up at competitive prices
Twilio is best when it is incorporated with email campaigns. Sending emails and seeing the user engagements to then incorporate SMS text messages has increased our campaign performance. Some planning and coding [are] required but a marketing generalist should be able to work with it.

We are an eGiftCard company that uses SMS as an integral part of user validation and eGiftCard usage flows. Between 2016-2019 (our earliest years) we had employed another programmatic SMS vendor simply due to the cost - we needed to validate our business hypothesis and the cost had to be minimal. Toward mid-2019, when the number of SMSes was at the scale of a few 10,000s, we started getting a lot more complaints about the effectiveness of SMS delivery. And that is when we checked options in the market and went ahead with Twilio - the major reasons we considered were (a.) feedback available on service from fellow startups, and a comparative analysis with other service providers on the dimension of "SMS delivery effectiveness" (b.) ease of integration for our tech team - documentation helped well (c.) set limits for auto top-ups. Since then our SMS usage has grown by a significant factor - 100,000s/quarter and Twilio has been a great fit for us; we don't think about our SMS layer anymore, so I think that's a job well done by Twilio.
  • SMS delivery effectiveness - rarely are non-delivery issues affecting us.
  • Auto top-up of account credits with self-definable limits.
  • Provides excellent documentation that leads to the development team breezing through integration.
  • The 2-factor authentication is the default for Twilio login. For several use cases, we want multiple members of the team to access the dashboard and the email/OTP authentication layer becomes a bottleneck. If multi-user admin privileges can be built-in, that works great.
  • As the scale of usage goes, pricing becomes a concern, and Twilio doesn't have a tiering built into the dashboard that we can leverage on.
Have shared some information in my earlier responses.

Our company, SnapEngage, is the leading provider of live chat platforms. Twilio SMS API is being used in our company for 5+ years already and is used for providing the possibility of creating a chat between our live chat platform and the customers of our customers (site visitors). A site visitor can create a chat with agents by texting an SMS and the agent will be able to reply from the platform. Put customer is buying of SMS number through our platform, so that their clients could have a chat via SMS. That's very nice for people who can just chat via SMS, so it gives more flexibility to communicate. Along with SMS, we provide Facebook Messenger and etc. Integration with Twilio went pretty easy. When our client doesn't want to use this channel, we just release the number to Twilio. All the logs we can see in the admin account logs. Also, we integrated the Programming Voice module, but Voice API is not used very often as much as SMS. Integration was done a long time ago, 5+ years. As far as I know, integration was performed smoothly, we don't have issues. Some time ago we had live calls using Twilio but not anymore.
  • Provide/release SMS
  • Texting via SMS
  • More visible logs
As we do in our company, it's easy to integrate Twilio SMS API for texting via SMS with clients from the USA. We are a US-based company but have European clients as well.

We use Twilio as a one-stop solution to all our messaging needs, we leverage it on our platforms to create the best developer experience for developing voice and text-based applications. Twilio has got everything covered when you talk about messaging--from sending out marketing text messages to sending out the voice notes to our customers from an IVR. Since we are a telecommunication-based organization, globally we try to have the same set of gateways/applications wherever possible and Twilio has helped us achieve this. We use Twilio across all of our business units globally.
  • Getting to know Twilio is super easy thanks to its amazing documentation, which is written in a very clear and simple-to-understand manner
  • Console is easy to use, things are easy to find, and navigation is great
  • Awesome reliability--we haven't experienced any downtime and Twilio's services are highly reliable and built for resiliency
  • Premium support is great, but they charge a hefty fee. The rest of the support tiers are not that great and we had some issues and friction with the support earlier when we were in the lower support tiers. But since we use Twilio globally and at a large scale, we decided to switch to the top support tier, although it comes at a cost but is good. I wish they provided at least decent support in lower tiers as well
  • We saw some API failures to the calls while initially implementing Twilio, reached out to our CSM, and he took some time but was able to fix that for us--never imagined the API failures from Twilio
  • Our customers have complained about very occasional call drops and bad audio quality
  • Delivering messages to some countries, like China, takes time
I would recommend Twilio to anyone who's looking for cloud-based messaging software, no matter if you're a business with smaller/limited needs or a multi million business with a massive call center/customer support team that requires high availability and reliability--Twilio is versatile enough to handle all your needs! It is a platform that scales as you and your business grows. It is also continuously updated with new REST API features and SDKs, which makes it a great fit for the growing tech industry.

We had a problem keeping engaged with Clients and we found that Twillo is a great tool for client connection. We use it to keep connected to our Clients.
  • Twilio helps us with Client email and keeps us compliant.
  • Because of Twilio, we rest easy knowing our communication our Clients is happening
  • It helps us avoid being blacklisted as spammers
  • We found it was easy to set up but it takes a little time to learn how to implement
  • Explanations of functionality were sometimes confusing and took longer to figure out.
Twilio for us has been vital because it helps us stay compliant with email. This means we are able to be confident that our communications with Clients happen in real-time and are not delayed because of our mail being redirected to a junk or spam folder.

We use Twilio as part of our SaaS product to extend its reach with audio and text phone communication: Twilio allows us to programmatically create a conference call between 2 parties who are already connected by our SaaS platform in a text messaging session, and allows text messaging to come from SMS channels too.
  • Very easy for developers to get started
  • Great API documentation
  • A lot of active community content and code examples
  • A robust platform, no significant outage impacting our services
  • The administration dashboard is complex - improved UX would be welcomed for the admins
Twilio is the go-to platform for developers needing to add phone services in their online services. With the merger with sendgrid and the extensions to Whatsapp and other channels, Twilio is becoming the standard vendor to provide all necessary complex communication technical services to a developer audience. Getting started is fast and easy with tons of code examples and exhaustive documentation.

It is a very good app to send SMS and mail via APIs. We use it to share information within our company and with clients too. We are also working on different modules of this app to be used in our organization it helps us to ease out our work. We would like to recommend this software to everyone.
  • It helps in sending SMS via APIs.
  • Helps developers to programmatically send and receive SMS.
  • Twilio use intelligent feature to send Emails.
  • Well, everything is good still we can improve the layout of the app so every user can easily use it.
There are so many times when you just want to share the information with other clients securely and do not want to share the secure data, here Twilio works best as it connects with APIs to complete your communication, in a very secure manner. This is the best software to establish a secure connection.

We implemented Twilio within a small service-based company that needed to point people in the right direction when they got in touch with the company. Whatever channel those people get in touch with us, such as Whatsapp or email, we can quickly streamline the conversation and then keep an accurate record of all interactions in the future.
  • Plenty of options of channels to offer as part of the tool
  • Integrations
  • Automating actions, such as emails and SMS confirmations of orders or support tickets
  • Experienced some technical issues in the past
  • Not the easiest to set up (initially) - this was the first time I used the tool
  • IT executives would find it easier to set up rather than marketers - it would be good if the tool was aimed more at marketing. This said product support is good
Programmable SMS messaging was particularly a very good (and enjoyable) process to create - the tool in this respect was really nice to use. With SMS messages, in particular, the logs or deliveries, etc., and very interesting and presented in an easy-to-use way. Whilst technically the tool is a little complex, the UI is well designed and inviting to use.

We were impressed by two things. The first was the flexibility of the architecture, which the primary RingDNA architect had first-hand experience with on a prior project. The second and perhaps most impressive thing is reliability. The fact that Twilio APIs were unaffected by the infamous April 22nd Amazon Web Services outage really spoke volumes about the stability of the platform.
  • Easy API.
  • Great support.
  • Twilio call flow and routing process is the gold standard.
The Twilio call flow and routing process is the gold standard, and we have used it to make things like RingDNA’s script suggest features happen. We’ve built things on top of it, such as the ability to associate channel information, such as search keyword usage and other call origin features that might influence what people picking up the phone should do or say.

Allows us to communicate with customers on a reliable communication channel (short message service). This allows us to target/send notifications (promotional, order status, service, etc.) to customers using smartphones or non-smartphones. SMS is legacy but still effective as it attracts attention, texts get read unline million push notifications all in all cheaper and effective method to stay in touch with customers.
  • Works great and helps businesses communicate effectively and programmatically
  • Light weight interface
  • Well documented
  • Magic SMS login
  • A cloud service provider should always have ways of improving pricing given this competitive industry
  • Consistency across the sales team
  • Customer service with instant messaging to suite customers from different time zones
Since the product was well documented it was very easy for us to integrate with the module we chose to use. Twilio SMS is well suited for organizations who believe in SMS marketing as setting up SMS marketing for e-commerce brands can be made incredibly easy with Twilio, templated message-flows, and more. Or some organizations may simply want a reliable SMS broker. How cool is it to send receipts via SMS for customers who cannot be bothered with apps/emails - simple yet effective.

We use Twilio to send text messages to customers and partners about their bill, progress on their injury cases, etc. We use that across the company but Twilio's use is heavier in some departments than others. In this day and age, customers want to be kept informed of status of their case/complaint. Customers want to know when a bill is generated, when a bill is paid and more. Twilio's SMS API allows us to keep customers informed and that increases their trust in us.
  • Easy.
  • Reliable.
  • Mature.
  • Requires advanced skills.
  • IT needs to be involved.
Twilio's SMS is very well suited to interact with customers via text messaging. While we have seen younger generation being happier with texting, we are also seeing texting picking up across all demographics. Twilio will generate/increase trust in situations when customers require rapid response or want to be informed of their account/status changes. Twilio's SMS is not the best for sending links to files, getting electronic signatures via links or sending large images etc. Expect IT to be involved and ensure that IT is given adequate information about your current AND future plans to gain the most out of Twilio SMS.
The best part is that we don't need to call Twilio. Barely ever does anything go wrong. When do have to call regarding questions about billing or account settings, they are always happy to help. We don't feel like we are burdening them. Support typically has answers for us in the first call and we seldom have to wait for escalations.
Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

From my almost six years of experience using Twilio, I regard it as the top solution for receiving and sending SMS, VoIP calls for two-factor authentication of our apps. Thus, it wasn’t a surprise when I joined my current company and found Twilio as their adopted voice/SMS API programme.
Asides from its efficiency, the major reason why we use Twilio is because of its large peer community, which makes it so easy to find solutions to all obstacles encountered while integrating Twilio, coupled with the quick and efficient response from the Twilio support team, at every occasion where-in I have needed assistance with using Twilio.
  • Strong resources provided by Twilio for users to easily navigate most technical issues.
  • Efficient support team - I get responses from Twilio on every occasions where-in I have had to contact them, within a 24 hour period.
  • Competitively priced sms/voice calls cost to any phone number globally. This is a major strong point of Twilio.
  • Twilio restricts log data rows, thereby affecting my inability to export complete log data.
  • Difficulty searching for sms logs, using phone numbers.
Twilio is efficient in terms of quick sms delivery to most locations, globally.

Efficient for customer engagement - Twilio makes it convenient to connect with our customers wherever they are using text messages and voice calls.

Phone number validation to prevent fraudulent signups.
Twilios response rate in terms of how quickly they respond to support tickets, is one of the best I have come across.
Twilios large peer community on the internet , easy to access Twitter tutorials provided by Twilio itself and available API references makes using Twilio an easy experience. Sincerely, I do not think anyone can get lost in the course of using Twilio, at least from my own personal experience and that of junior engineers and developers on my team.

Twilio flex is being used for our inbound and outbound call center, we needed to move from our on-prem solution to the cloud. Twilio is being used by all our teams in our company. What's great is we can work anywhere we want just as long as we have internet, we are good. The times that we are in today gave our employees that flexibility vs. having to work in the office. Another thing I love about this system is that it can directly involve the SIP trunking within the Twilio platform. Twilio is a simple, user friendly way to log in and out of work activities.
  • Easy to see my team in one place, when they log in and out and what call status they are in.
  • Twilio is a simple, user friendly way to log in and out of work activities.
  • Excellent services and support.
  • The omnichannel feature which allows agents to get request from all channels.
  • Documentation can be improved for training and learning.
  • You will need an IT team to implement this solution or need to pay for PS work.
  • Getting the logs is a bit difficult for support.
With Twilio, you can start from scratch to build your own contact center in the cloud. I did know a lot about VOIP before, but still needed to learn a few things for this solution. When I need to travel or my agents need to travel for work, they can with all mobile services you can expect (voice, SMS, MMS). The pricing is very good for this and the global user interface makes the whole system pretty easy to manage and use. I only use a few features from the platform, but the possibilities are huge being in the cloud! What is great is they are always working on new services. And Twilio is now really recognized as a leader in the communication space.
I would say support is not the greatest at times. Sometimes, the turnaround on a support ticket can be 24 - 48 hours even if it is a tier 1 issue. Other cloud contact centers I have worked with can resolve some tier 1 support issues on that same day.
I gave them a 10 here because from the agent level this system is very easy to use for them. Supervisors love it because of the reporting they can get and the ability to monitor and train/coach their agents. The only piece where it gets tricky is from the administrator side of the house, but if you have a good IT team there is nothing to worry [about].

In the healthcare industry you need to find different sorts of solutions to reach out to patients for different reasons. It may be appointment reminders, marketing purposes or to update them about requests that they have made. There are plenty of companies out there who do this for you, including the interface with the biggest names for PM systems and EHR, but since we have an IT department and people dedicated to develop custom software solutions, Twilio was definitely the best option to choose price-wise and implementation-wise. It gives you full flexibility to use the system as you wish, write any logical structure to implement your solutions, and it's really cost efficient in comparison to other options.
  • Customization.
  • Price.
  • Documentation (easy to implement).
  • Speed.
  • It is not a direct consumer tool.
  • You will need an IT team to implement these solutions.
  • It's a very specialized tool.
If you have a software development company this is your best option, the cost per message is miniscule, and the it will integrate well into your software. There is a lot of documentation and the API is easy to use once you get the hang on it. If on the contrary you are a consumer who wants a product ready to use by just inputting some data, this is not the product for you. This is the product that the companies that try to sell you those ready to use products use.
I haven't had to interact with them in a lot of occasions, but when I have it was with very deep specialized questions and the person that took care of me know the software inside out. They knew how to address my questions and help me solve my problem. They also have a lot of resources in their community.
The versatility of integrating this into code is just perfect. You can design your code and just use their API for specific functions. Dealing with vendors with this solution with API's is usually more complicated because they are designed with a single goal in mind, let's say appointment reminders, but with Twilio you get the essence of being free to send a text message for whatever reason, and that with custom code is a very powerful tool.

We use the Twilio voice and messaging APIs to communicate with client communities harmed by internationally financed projects. We have to reach people with extremely limited Internet access and low literacy rates, so the voice API is a key tool for us in communicating with dispersed populations about the harm they face.
  • Fantastic documentation
  • Good customer support
  • Messaging functionality in lots of countries
  • Fantastic error messaging and debugging
  • Not supported in all countries
  • Prices can be high, particularly internationally
  • Programming trees of voice responses can start to get really unwieldy
Twilio has positioned itself as an all-in-one messaging service, and it honestly does almost everything really well. The API documentation is super clear, it generally works smoothly, and when things go wrong, alerts and the debugger do a great job of helping you find the problems. If you need to build out any sort of integrated response system (voice calls, SMS, emails, WhatsApp, etc.), I can't think of a better service than Twilio. If you need more automation, though, with layered in AI functionality, there may be other (albeit more expensive) options that are better suited to your use case.

A year ago we were using Twilio SMS as verification code register/login for out app. Now days we have evolved and since we implement a WhatsApp register/login we had to do all the process with facebook and Twilio in order to have a verified WhatsApp Business Number from Twilio. We implemented our login sending whatsapp code messages and later we implemented a CRM through Twilio whatsapp for our customers (equivalent to others like intercom, zendesk, etc. but with whatsapp). Additional we still use Twilio SMS in order to verify potential leads instead of using captchas.
  • The ecosystem is just good and is online 99% of the time
  • They provide you with needed tools in order to implement solutions that you have in mind.
  • As for Whatsapp Numbers they give you personal follow-up from the beginning until the implementation from the side of Twilio of course.
  • Well when we talk about Twilio we already know is gonna be hard to implement since are most of the time API request. I know that Twilio has partners with several business that make 3rd party integrations so an easy way to find in Twilio those integrators might be useful for those who want to use Twilio but they have the tech barrier against them.
  • Twilio WhatsApp Business didn't have verified numbers for Mexico, so our business is using a US whatsapp verified number business. It could be nice to have a local Mexican number in order to be closer to our customers. For international business this might not be necessary.
  • Cost even for WhatsApp Business is slightly almost the same as sending SMS we were expecting to savings by using Whatsapp instead of SMS so a better differentiation in price will be a good improvement.
Right now we already find out how to implement WhatsApp Business through Twilio like a self development application or through 3rd party solutions. This way we are pretty comfortable in recommending Twilio Whatsapp to other colleagues and actually we have done it. Also if colleagues [don't] have the same technical skills to make the implementation we can recommend 3rd party integrations that automatically give all the main features a business would like to have from whatsapp as CRM, multi seat and whatsapp broadcast.

[Twilio is] used to manage communication with our clients in the ways that our clients work outside of emails. It allows us to communicate with our clients by voice calls and text messages. Additionally, we use programmable wireless to provide on demand connectivity as we travel with our equipment.

Twilio provides a set of highly robust building blocks for communication and connectivity. It works extremely well with our business which fluctuates in demand and we can scale up and scale down very easily at any time.

Especially the programmable wireless service allows us to deploy equipment anywhere without worrying about figuring out a short term contract with the local cell carriers.
I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries.

With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.
Overall the product API is extremely well documented so it is very easy to build a product with their technology. The website is a little bit cumbersome to use as they have greatly expanded the number of products that they have over the years, but the dashboard UI has not been improved much since.

Good interface to connect with different API systems for communication through different channel[s]. Twilio has good market coverage of the client across the globe for generating revenue through multi-channel approach. It works with [a] programmable feature that makes life easy for every user. Automated call is one of the advance[d] feature[s] of this tool.
