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.

Velocify, Mailchimp and HubSpot CRM

Reasons for Choosing Mailgun

Utilizing a new software CRM integration, they favored MailGun so I gave it a shot and migrated over, happy I did, everything is incredibly smooth.

Reasons for Switching to Mailgun

Again, the main required integration for our CRM, and that is perfectly fine with us because it is smooth operating on the free account, I'm sure will be great on dedicated IP account.

Mailgun is the most developer friendly and cost-effective transactional email service/

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.

Alternatives Considered

Sendinblue, Amazon SES, SendGrid and Mailjet

Reasons for Choosing Mailgun

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

Reasons for Switching to Mailgun

Dashboard, ease of implementation, the support team was great too and offered very quick response times.

Good, but crap customer service

They suddenly and mistakely suspended one of my domain and took ages to get it back. They told me that their back-end service sometomes does it by mistake... not sure why it took them days and days to reply, and still not resolved after almost a week... (I was using a mid-range package, so not the the free tier.)

Pros

Easy to setup and use in WHM
Clean and userful dashboard

Cons

Customer service is slow and useless
More expensive compare to others

Great Software Gone Greedy

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.

Bare-bones but super reliable and easy to use.

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.

Alternatives Considered

Mailchimp Transactional Email

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.
