About Mailgun

Mailgun is an email automation service built for developers. It offers a complete cloud-based email service for sending, receiving and tracking emails sent through your websites and applications. Mailgun's intelligent inbound routing and storage enables you to know exactly where your emails are ending up.

Built for developers, Mailgun is a set of APIs to integrate email. It supports all of the most popular languages including PHP, Python, Ruby, C# and Java. Tracking & analytics features, including A/B testing enable you to track all emails and maximize their chances of avoiding spam filters and reaching inboxes.


Key benefits of Mailgun

  • Mailgun's software automatically manages the delivery process to give your emails the strongest chance of landing in the inbox. With the API control panel, you'll always know what's happened to every email sent.

  • Each Mailgun domain is an isolated sub-account with its own sending queue and reputation. This way, your transactional emails won't get stuck behind your newsletters.

  • Easily personalize all emails for each user with Mailgun's recipient variables feature. Image URLs can be included too, to personalize the entire look of the email.

  • Route and forward email directly into you inbox or app with Mailgun's intelligent inbound routing and storage. Email parsing turns your emails into easy-to-digest structured data whilst spam filters keep out unwanted emails.

  • Carry out A/B tests and report on your data with Mailgun's tracking and analytics features. Always know what is happening to your emails with searchable logs.

    I use several different email service providers, each for a different reason. I use Mailgun almost exclusively for inbound mail processing. The inbound processing also offers a preliminary spam filter so that at least most of the spam isn't sent further down my process chain.

    It's super easy to set up inbound routes using specific strings or wildcard matches that will accept mail and forward to multiple different recipients. These recipients can be either proper email addresses or webhook endpoints.

    I often use the address forwarders in combination with the SMTP outbound service to build a system where Gmail users can use their free gmail.com account to receive and send emails from their small business domain without having to sign up for and configure a proper G Suite account.

    I use the webhook forwarders in combination with Zapier and Integromat to receive any emails that need to be processed and automatically acted on. Mailgun normalizes all the different types of email and attachment encodings and packages the message data into an easy-to-parse JSON package that makes it super easy for me to grab what I need and reliably act on the normalized data.

    Pros

    Inbound mail processing with spam filter
    Free tier offers great sending limit
    SMTP and API integration for outbound messaging

    Cons

    This product doesn't offer any sort of backend mail building or sending functionality. It's only an engine for sending messages. This means you'll have to build your messages somewhere else and integrate them into your sending code.

    Reasons for Switching to Mailgun

    The pricing structure for Mailgun was a much better fit for my specific needs of inbound mail processing. Mandrill provides inbound mail as part of a much larger and more complete service offering that was not necessary for my use case. I simply wanted a service that would accept, process, and forward messages without all the other tools built into Mandrill.

    Outside of them changing their payment tier / plan system I haven't had any issue with Mailgun. I always found their customer service great and the product itself to be fantastic and does exactly what it's supposed to. I just really wish they brought back the routing feature to the free tier.

    Pros

    Great API, Super easy to integrate into various types of website / webapp setups. I previously used Mailgun for a variety of different integrations and never had any issues. Complete frictionless integration from beginning to end.

    Cons

    I dislike that the features we used to get for free are now hidden behind a paywall. Features such as routing emails I find to be rudimentary and were previously built into the free / pay as you go tier. Now it is locked behind the $35 dollar tier. This is a pain for small businesses that want to accept a few emails from a professional email with their own domain. Now to unlock that feature they must over commit to a tier with an allowance of 10k plus emails a month. This I feel has squeezed many small businesses out of using their service and it has definately moved me from recommending & using them in future as I would have previously for my smaller clients.

    At that point in 2018 it was easier for me to get started with Mailgun and there were more tutorials and information of how to integrate it.

    Unreliable. The one thing that an email services cannot be.

    Pros

    Not worth my time to post any pros with their software. Same functionality as competitors.

    Cons

    Our email has been down this whole morning. No explanation or response from Mailgun.

    After many unsuccessful attempts to log in to our Mailgun account, we got a popup saying "We are migrating some systems" -- no warning of this in beforehand either.

    Email is a very critical part of our business. We assumed Mailgun would be a reliable partner — apparently not.

    Please stay away from Mailgun. I can’t recommend this to anyone having a serious business. There are more reliable and cheaper alternatives out there.

    Mailgun was one of the most developer-friendly transactional email service providers previously until they removed their free plan. However, the ease of implementation and support by different plugins and software make it a really good tool. DNS is easy to configure so we have no issue with deliverability. The dashboard is also great and offers good logs and graphs.

    Pros

    Great documentation, 10k emails on the free plan was great previously for the prepaid plan is okay. Good API and interface.

    Cons

    Downtimes and deliverability issues can be daunting.

    Pricing mainly. Maildrill was taken over by MailChimp and pricing got very high.

    We use mailgun for all of our transactional email. We manage, from a single account, a lot of our domains. We always have detailed insight into what is happening with our email deliveries. When things go wrong, there is enough information to find the cause.

    Pros

    Ease of setup. Transparent pricing. Free tier goes up until a really high scale. Can use it via API or smtp, whatever you need.

    Cons

    Support is a little slow for non paying plans, but that is expected. There are no alarms in place for when something starts going wrong unexpectedly.
