I like being able to quickly search for a specific email address to determine if that email successfully delivered, and if that individual opened the email (and at what time). Review collected by and hosted on G2.com.

Reviewing the sent email logs can sometimes be cumbersome. The "Quick View" function (which is intended to view the original email sent, not the MIME) doesn't work. That may be a setting with my employer, but if that were/is the case, my expectation would be that the "Quick View" button would be available. Review collected by and hosted on G2.com.

it was very easy to set up and implement Review collected by and hosted on G2.com.

awful customer service. i signed up for a trial and then my account was disabled as soon as i started using it, citing that there were problems verifying my business (even though it was already verified). i was asked a few questions about the nature of my busines, the source of my leads, and links to my business website's privacy policy and terms of use pages. i happily obliged and provided them with all the information they requested and they still replied telling me that they decided to permanently disable my account without offering any explanation. i wished to reply to them, appealling this decision and properly escalate with a supervisor or manager, but i was not even given this as an option because it turns out that, after their latest message, they even blocked my email address from making any further replies. this is ABHORRENT customer service. i was presumed malicious throughout the entire process even when i fully cooperated with them. i cannot, in good conscience, recommend this service to anyone. i'll be taking my business elsewhere.

Ease of Integration, nothing else, that's it. Review collected by and hosted on G2.com.

The way they push all the responsibility to the customer. When contacting customer support they deny their responsibility in ensuring the service operates safely. Review collected by and hosted on G2.com.

Nothing much, it's hard to work on when you want to scale, they block you all of a sudden even though you are a completely legitimate business, never had an issue with any other provider like I had with them Review collected by and hosted on G2.com.

Simply that they wait for 1 month so they can charge you and then they block you like you were some kind of a spammer even though you were pretty transparent and legit business from the get go. I have worked with Mailgun multiple times and always ended up having some issues now I will no longer refer anyone to Mailgun. Review collected by and hosted on G2.com.

Very relialable service, easy to setup, intuitive UI, endless configuration option for small business or enterprices. Review collected by and hosted on G2.com.

None. Tried many competitive services but Maligun is simply flawless for our use. Review collected by and hosted on G2.com.

Easy to use, easy integration and easy access to all information. All in one place Review collected by and hosted on G2.com.

The email templates should be more intuitive Review collected by and hosted on G2.com.

the system is pretty simple, easy to monitor ip reputation, good reporting Review collected by and hosted on G2.com.

it more design for developer, if you want to send bulk emails with upload list, you need to have developer to send it with api Review collected by and hosted on G2.com.

The documentation for their API is pretty well done, so it is easy to implement their solution. We strictly used it for email validation. Review collected by and hosted on G2.com.

There are multiple downsides to Mailgun, but the level of support is one. We typically would perform a few thousand client-side email validations per month. One month, we ended up with over 400,000 in a single day, that were due to bad actors. We would have assumed Mailgun would have protections in place to prevent a couple of IP addresses from running up an account, but they don't and wanted to charge us for all those email validations.

The worst part is we don't even have a way to "see" these validations. They literally just have a master counter with no report or anything showing the validations that took place, so the counter could just be whatever they want to make up.

When explaining to support our use of their API for client-side email validations, they simply wouldn't listen and kept providing generic boilerplate responses to reset all our "private" API keys, which were never even used. Review collected by and hosted on G2.com.

When it works, it's perfectly up to task, but when things go wrong, you're left stranded Review collected by and hosted on G2.com.

The customer service, since being bought by Synch, has just decreased and decreased until it's almost non existent.

Mailgun has a large number of EU customers, and they even have an EU server set up and interface (which, bizarrely, you have to switch to in order to see EU data), however, their Customer Service team only operates in US time, specifically Monday through Friday from 7am to 7pm CST. We're in the UK, so that means we have to wait until 3pm on a standard working day in order to speak to someone!

So, in the absense of speaking to someone, they ask you to submit a ticket, which invariably doesn't get responded to. Point in hand - I raised an urgent ticket yesterday morning, it's now 24 hours later, and they still haven't responded. In case you're thinking that's because I'm on the free plan, nope. We pay Mailgun nearly $1k a month!

When you do finally speak to someone, they're worse that useless. They're basically a triage team, and all they do is farm your issue over to some mysterious back end team to try and resolve. The amount of circular conversations I end up having with the triage team, where they refuse to accept any responsibility whatsoever for issues I'm facing, is farcical.

Oh, and on a technical note, updates made in the UI don't instantly translate to the back end, so even once you've tried to fix something yourself, you have no idea when that fix will actually be implemented.

I didn't wnat tio write this review, but Mailgun's inaction give sme no choice. Stay well clear Review collected by and hosted on G2.com.

It is reliable and never goes down. It is easy to use. Easy to integrate and implement. We use it non stop. Review collected by and hosted on G2.com.

I wish it could retain emails for a longer period. Review collected by and hosted on G2.com.
