Sinch Mailgun vs. Verifex

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 I do think they have some room for improvement with the lack of templates and the outdated UI log handling/filtering.

• Its SMTP is very easy to use and it integrates easy with all CMS and frameworks.
• It allows you to have a record of the incoming/outgoing emails and get useful statistics about them.
• Thanks to their 5000 free emails per month, it is a very good option to startups and small companies.

• 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.

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.

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.

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.

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.

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.

Incentivized

• ROI great for client campaigns
• Great for getting the right message in front of the right people at the right time
• A valuable part of our tech stack as a lead gen agency
• Ease of use when plugging it into other tools (speed to implement)
