We are solving transactional email needs for a startup I work as a CTO, does a great job there despite pricing not being flexible enough.

Pros

Mailgun is a service that was created by developers for developers. Their top-tier documentation and code is self-explanatory and should present no issues to integrate in just a few minutes. The service itself is reliable and has the latest bleeding edge features. Their customer support is very effective and can get issues solved promptly.

Cons

Mailgun's pricing has only gotten pricier and pricier with time. They are not even able to provide discounts that are not in their scheme and it is up to you to simply accept that when there are many competitors on this market. The service itself is very robust but this inconvenient made me think about other options after some above-base level features were needed.

Incredible Deliverability, Clean Platform, Success with MailGun!

Super pleasant, great chat support, fast email support replies, always quick to help and communicate.

Pros

Clean UXI for navigating the system, simple set up, clear dashboard to find issues quickly and navigate around the site. Ability to clean database lists to minimize bounce. However, the BEST part is they are free up to 10,000 emails a month, which is a ton! So to give the full custom power of connecting your domain and sending out, that's a huge value. I will get over that limit and upgrade soon, but that is an incredible way to start a relationship. Almost a year of free service to use their system versus my server.

Cons

I actually have not found anything that I do not like. Many will complain about high bounce rates or going into spam. I find that issue arrises on multiple factors outside of mailgun control, such as the receiving server, and the mail habits of the person opening it, do they get a bunch of spammy mail already? And was the mail piece written in a poor nature, this increases spam folder direction, however, they do have dedicated IP service for those wanting to mitigate one area of cause for spam direction. Again, never been my experience.

Wanting to send only notification emails to our users through Mailgun, our very bad experience with the support team killed any interest for the product.

Pros

Mailgun was easy to set up, straight from Heroku. It worked well for some time.

Cons

Despite a paid plan and all the proofs the Mailgun staff could need, they restricted heavily our ability to send mails to our users through SMTP.

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.

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.

It was already a week and the slow responses from support didn't help. Maybe I got impatient and switched too quickly. The software looks good, it's just that I needed to implement something quicker

We use mailgun for all of our email sending needs across multiple servers and products. We implement mailgun as the default mail sender for any new projects too.

Pros

Its api is very simple to use, most PHP frameworks come with mailgun integration out of the box - if they don't, mailgun supports standard smtp anyway. Great usage graphs and multiple regions to send from. Is makes it very easy to send emails from php applications which would normally be blacklisted if you use standard php mail from inside a VPS on e.g amazon/azure/vultr/digitalocean. Very generous free tier.

Cons

Their anti spam measures can sometimes not work - if your sending details have been compromised you can be hit with a pretty large bill before you realize someone has been sending hundreds of thousands of emails on your behalf.

Pros

The best would be their free tier, they recently changed their free tier but you still get free 1k+ emails per month. This is thier "pay as you use" tier. Very usefull if you're still new as you get all the features of a paid service. Very cheap even when you exceed the free emails.

Cons
