Considered Both Products
OneSignal
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 …

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
Twilio excels in customer service applications, enabling automated SMS updates or voice calls for order confirmations and support. It's ideal for implementing two-factor authentication, enhancing security for online services. However, it's less suitable for businesses needing in-depth, custom telephony infrastructure, as it primarily offers standard, API-driven solutions, or for regions with limited internet connectivity, where cloud-based services may be unreliable.

Cons
OneSignal
  • 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.

  • In my opinion, online support is extremely subpar for clients.
  • In my experience, no way to talk with anyone without a $1,500 investment monthly in their service.
  • In my experience, be prepared to wait at least 2-4 days to receive even one response from their support.

We have standardized our processes surrounding Twilio. The entire process just works! There is no significant gap that we need to fill. Instead of thinking about Twilio's replacement, we'd rather focus on our customers with Twilio. It meets all our uses-cases currently. We haven't even explored the entire suite of applications to determine what other use cases we may potentially use.

Usability
OneSignal
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.

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.

The problem tends to be us, the user, rather than Twilio. We don't reach out to support fast enough (spend time struggling), but when we have, they've solved our issue immediately. We are rural, so there are signal issues to accommodate, however, we find that a few staff on a few cellular networks can triangulate where we all have signal to put up a sign.

Support Rating
OneSignal
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've never had to contact Authy's support. Of course, that's because Authy is so simple and easy to use that there hasn't been any need to. Authy correctly implements the time-based one-time password (TOTP) protocol, and becomes it conforms to the standard, it easily replaces Google Authenticator for your needs.

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.

Twilio was referred to me by a business colleague, and I can't be more thankful! Twilio has helped my Facebook page by leaps and bounds, and I haven't even considered trying another chat option for my page. It is easy to set up, and customer service is quick to answer any and all questions you may have. I highly recommend it!

  • Adding in phone numbers onto our onboarding sequence has increased our user activity by about 30%. We believe due to the users being more invested in the application now.
  • On top of that, our first SMS has increased our week 1 retention by about 15%. Pushing users to go on the app more than 2-3 times has been a struggle and SMS seems to be a solid driver in retention.
