Chose OneSignal
OneSignal comes with a free plan and easy integration, unlike CleverTap which has a starting price of $200 per month and a difficult integration process. That is why we selected OneSignal instead of CleverTap.
Twilio
Chose Twilio
Those solutions are just not the same, Mailgun is a programmable SMS API with really low cost and is so far compared with Twilio SendGrid but since we are using more Twilio SMS or Whatsapp, [it's not used for] the same purpose. As OneSignal is an all in one solution for being …

MailUp
Great for marketing teams looking to quickly deploy emails without the need for HTML coding.

OneSignal
I think One Signal is very well suited for mobile app owners who want to be in touch with their user base more easily by sending push notifications and in-app messages. I'm not sure how well that works for SMS messaging as I haven't yet tried it. I wouldn't necessarily recommend it if your in-apps are very rare.

Twilio
I found Twilio to be excellent and very easy to use for a programmer in all aspects related to voice, SMS, and other features utilizing their API. I found the node client to be excellent and helpful. We previously used the Apex client for Salesforce before it was discontinued. Although we try not to use Twilio from Apex anymore, using that client was easier than implementing our own.

  • Is still in development: we know OneSignal is still in development and sometimes it takes longer to create or fulfill certain features.
  • Payment: payment menu is not at the glance, [and] is just difficult sometimes to find -it is a minor issue.
  • Send to certain custom segments through specific OneSignal IDs; you can do it though API doing a GET call with tools like Postman. If this can be done from OneSignal it would be great.

  • Segment’s email identifier is case-sensitive, which is ridiculous because emails themselves are not case-sensitive. This means that if I send a capitalized email address in an identify call, it will create a duplicate user rather than matching it with the lowercase email. I think this is a technical oversight that should be corrected.
  • I’d like to see more information about the eventual transition of existing Frontline customers to Twilio Flex
  • I’d like to see some integrations between Twilio Studio and OpenAI or another open source LLM to provide automated responses, if this hasn’t been done already
  • I would like to be able to drag and move the actual lines connecting the steps in Twilio Studio, sometimes mine can get pretty messy
  • I think a Bug Report form would be beneficial for developers

Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

I give an 8 in this question mainly for 2 reasons: the products even if they look like complete and are highly customizable and usable, they are still missing some logical features. For example, send messages to a list of users - now days you can do it with postman and get calls. A second example is App messaging that is still in development and has many opportunities.

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.

Twilio executes what it is designed to do: send SMS messages at scale while providing very good deliverability. I believe that Twilio is very good at what we use for adding SMS messages to our comms strategy. We can see those messages get opened and replied to, which is exactly what we are looking to achieve.

Their customer support has been top-notch. They are able to assist you in getting through any problems that you may have and respond in a very timely manner. I've dealt with them on 4-5 instances over the years and my issues were always resolved within a matter of a few business days.

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.

In my opinion, OneSignal documentation / API is more friendly [than] Firebase. Maybe because Firebase is already "too big," but OneSignal is focused on one solution that giving our notification through to our customer. In that case, OneSignal is chosen by our company. Several years after that, Firebase announced it supported [the] iOs platform too but our company already using OneSignal to our notification provider.

We evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.
