Mailgun is a transactional email API service which was owned and supported by Rackspace (acquired in 2012) and then spun off in 2017 as an independent and standalone entity. It is now supported by Sinch since that company's acquisition of Mailgun and Mailjet, through acquiring Pathwire.

Even with the list of negatives, Mailgun is still a great solution for how easy it is to work with and how ubiquitous it is to find examples and libraries out there on the internet. The company has great support and are usually quick to address and fix things. I do think they have some room for improvement with the lack of templates and the outdated UI log handling/filtering.
Twilio is well suited to sending SMS reminders to prospects on the lead-up to sales appointments. This has helped us improve attendance rates for these meetings. We also use Twilio to communicate with these prospects post-meeting to make offers on products and services and for feedback on their meeting.
Mailgun is used by spammers, and sometimes your assigned mail server will get blacklisted because of other users on it.
If you end up with a mail server that is blacklisted, your mail will go nowhere. And, below the $300 and up pricing tiers, there is no one at Mailgun to help you get this problem resolved. You are just stuck.
In other words, Mailgun is unreliable as a mission-critical service. I would strongly recommend using a service with better processes in place.
Authy does not support the "push button" multi-factor authentication from your application's native apps. This means if you want to use Authy, you still need to use TOTP based codes.
Not really a shortcoming of Authy, but it does nothing to help with multi-factor authentication using text messages - those are still sent to your platform's messaging app.
Authy doesn't always display how much time is left before your current token expires, making it difficult to know how much time you have left to enter the current code.
We are happy with Twilio because the price per message is low. The API is not difficult to implement and the documentation is very complete. Twilio as a company keeps you well informed of issues that happen. They also offer free online workshops or conferences to make notices of new laws, etc.
The time for the initial setup is very quick, since you can start sending (thus developing) from their sandbox in no time. The actual configuration involves, as usual, some DNS changes that may require time but are well explained and documented. Once everything is set up, there are a lot of monitoring tools that you can use to optimize your lists.
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.
There have been a few minor outages through the years, but nothing more than a few minutes. These small outages are to be expected in any kind of a SaaS product, but Mailgun handles them very well. We designed our software to just retry sending after a while if there is an outage. As far as I know, we have never had to do more than a few retry cycles. This is all automated on our end, so we rarely even notice. Our customers have never noticed any mail sending outages.
The API and the deliverability of emails is excellent. Their API is very responsive and performs perfectly fine. I have no complaints there. Their management interface though (accessed through the web) is pretty slow though. Searching through lists of emails when I'm tracking down a problem for a customer can take 10+ seconds which is annoyingly high for a modern web app.
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.
MailGun's support staff is both friendly and helpful. They were very instrumental early on with helping out during the setup process by answering questions, providing documentation on best sending practices, detailing information about the advantages of sending from a dedicated IP rather than an IP pool, and helping us to remove ourselves from blacklists.
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.
Not really a con but I typically choose SendGrid over Mailgun simply because I've been using SendGrid for so long. Overall, SendGrid and Mailgun are both rock solid and very affordable. You could probably flip a coin on which one to use. I would definitely look into SendGrid's Accelerate Program too.
We have looked at some of Twilio competitors, like Infobip, Sich and Bandwith. Prices on all of them for voice minutes and SMS are way cheaper than Twilio. But none of them seem to offer as many features and ease of use as Twilio. Specially from an API point of view
Over the past six years, Mailgun has scaled with our growth very easily. We haven't had to make any code changes to handle our larger volume today, and their pricing has scaled naturally with our growth. As far as I know, there is nothing we will need to do in order to grow 10-fold. Mailgun just handles the load really well.
We found that associates who had the opportunity to respond to a survey about their assigned job were 37% more likely to return to a job site
We were able to reduce the number of resources required to manually respond to associates using Twilio Studio, so those resources could have more time to complete other tasks
We were able to scale the number of associates who received survey messages at least by a factor of 8 without increasing our resource demand
