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.

ZeroBounce offers monthly plans for starting at 2,000 email addresses that start from $18 per month. They also offer pay-as-you-go volume pricing that decreases as you scale, with credits that never expire. Enterprise customers who need to validate more than 1,000,000 email addresses per month should contact the ZeroBounce sales team for a customized quote.
Mailgun's pay-as-you-go pricing structure is fantastic, especially if you don't need to send that much email. The pricing, including the free tier, is much more generous than what you can get with some pricier providers, like SendGrid. I mainly just use Mailgun as an SMTP server for web services, and the service has been set-up-and-forget, which is great because I never even have to log onto the Mailgun website and do any work. Mailing list support also looks great for rolling-your-own and not relying on more expensive mailing list services.
ZeroBounce is well suited for any project that requires list hygiene. If you're not actively emailing people and checking the response, it can be hard to know where or not their email address is still active or not. ZeroBounce provides a quick and easy way to check those emails for you without actually sending them an email. If there's a current customer list that you want to clean up, you can run it through ZeroBounce and remove anyone that is determined invalid for a better delivery rate.
No built-in templating features (This was a bit sad after coming from Mandrill which excelled at this)
Dashboard UI (although easy to use) is a bit dated in appearance
Logs are cumbersome compared to Mandrill
Setting up TLD (top level domain) names (things like .online or .church) that are not common require an email to tech support (this is annoying)
Sometimes can be slow in delivery
Shared IP addresses can be SPAM filtered or delayed (requires an email to support to have a new one assigned - Note: this can be mitigated by buying a dedicated one for a monthly fee)
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.
Because it is a tool with a very clean and easy-to-understand interface, with easy file uploading, clear sections, and everything necessary for the validation process. The only part I really don't like is the fact that you can only download a .zip file with several Excel files, when I always use the same one. I feel that this hinders the process because it adds a couple of unnecessary steps.
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.
You can't seem to get ANY support until you shell out hundreds of dollars per month. I even did this when we could not deliver mail with Mailgun, and the response was slow and inadequate. Nor would they refund my money. I'll never be a customer of Mailgun again.
We have used ZeroBounce for about 18 months and it works flawlessly. We are able to get all of our questions/issues answered immediately. Felt very comfortable with the product immediately - used their web site which walked us through it and were able to get up and running within minutes. I really haven't had any issues that required support.
To be honest, the tools are quite similar and again I dont recommend using them as a standalone products, but they power the work we do via CRMs and our marketing campaigns. Mailgun integrates slightly better which it is why it is the preferred choice for our agency, as it integrations options seem to be better
ZeroBounce has better brand value and brand recognition compared to competitors in market. NeverBounce may still do a little better compared to ZeroBounce just because its a ZoomInfo company and has ZoomInfo data to back it up. Pricing need to be improved. Still we chose ZerBounce because it was best in business for email validation.
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.
By not investing in our mail server, we have saved huge amount of money and time. For configuration and installation of an email server on Linux-based server, we would have to hire a network administrator.
If email delivery is an issue in a hosting provider, another solution is to switch the hosting. Fortunately with Mailgun, we didn't need to try different hosts and experiment which one works best for emails. We can stick to our existing web hosting provider and would not need to change it just for the sake of improving email deliverability.
The pricing of Mailgun is very cheap and straightforward. First 10K emails are free every month and that's a big advantage for our organization because our volume of emails is rarely more than 10K per month.
