Use Cases and Deployment Scope

we use Sinch Mailgun to deliver emails to our clients using our own domains. we can add multiple domains in one account and it supports large amount of email delivery at very fast. It also help us to monitor the email deliverability status which we can check latter. They also provide API service we can use this to integrate in our applications.

Pros

Monitoring email deliverability status
Restrict unidentified IP's from sending emails
Fast email delivery to large amount of users.

Cons

As per my uses I don't feel anything missing or need any improvement.

Likelihood to Recommend

For our organisation we were need of a reliable and fast email delivery system to use in our applications like in Rest API form, so the API Service from Sinch Mailgun is best suited for us and we started using this. Also for security purpose they have IP whitelist feature which restricts unidentified server from sending any emails.

Use Cases and Deployment Scope

We use Sinch Mailgun both as end users to send emails from internal systems (like CRMs) and as cloud providers to final customers for various purposes, mostly to manage custom transactional emails from the platforms we develop. In both cases we handle the configurations, templating and actual sending of the emails.

Pros

Message queuing for bulk sends
Templating with variables
Great APIs

Cons

Initial setup for email tracking
Better SPF management for already cluttered SPF records
Email localization (same email in different languages)

Likelihood to Recommend

Sinch Mailgun is a very user and developer friendly email sender with lots of options and monitoring capabilities. However, you should take in mind that what Sinch Mailgun does best is the actual email sending, and it's not a fully fledged marketing platform, for which you need an external service/CDP/marketing platform.

Mailgun delivers on reliability and a good feature set

August 17, 2021

Use Cases and Deployment Scope

We use Mailgun for all our outbound emails from our Rails app. This includes transactional emails to our users but also is the backbone behind our reminder system. Our reminder system sends periodic emails on behalf of our users to their customers. We also use their API to track the delivery status of each message and expose that information to our users.

Pros

Their API and webhooks are excellent and reliable
They have great tools that help us increase our deliverability and reduce the chance of getting marked as spam
Their suppression lists are easy to manage

Cons

Their management user interface is a bit slow, searches take quite a while which can be frustrating. But we don't use this interface often, we mainly use Mailgun through their API behind the scenes, and it works great.

Likelihood to Recommend

We have found Mailgun to be suited very well for the email sending needs of a Rails app. It is excellent for transactional emails and easy to integrate into a Rails app. We have also found it to be great at delivering mass mailings on behalf of our customers. I've not found a use case where it isn't a good fit with regard to email sending. We are very pleased with their service.

Mailgun, sending mails in the best way possible

Rating: 10 out of 10

June 10, 2020

Use Cases and Deployment Scope

Almost all of our internal email is being managed by Mailgun. We use it for almost all of our clients as well. It is easy but powerful enough to integrate with CMS like Wordpress or Drupal, and with frameworks like Django, with almost no effort. It has allowed us to centralize several email domains and email addresses and to manage them in an easier way

Pros

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.

Cons

The new dashboard is a little complicated to understand, specifically if you have been working with the previous one a long time.
Error feedback may be improved when using API.

Likelihood to Recommend

Mailgun is for you if you have technical knowledge about using APIs and integrating email systems via SMTP or similar. It is powerful, useful and easy to use.

However, if you are a non technical person, it may be hard to use it. In that case, this is not the service for you.

Transactional emails made easy

Use Cases and Deployment Scope

We use Mailgun across the whole organization. We use Mailgun for all of our transactional emails.

Pros

Dashboard and reports
Stability and performance
API quality

Cons

Some better integrated tools to review your email reputation directly.

Likelihood to Recommend

We use Mailgun for transactional email everywhere. No matter what we throw at it, it always works as expected. We don't use it for marketing campaigns because in those cases we need to be able to make constant changes and tweaks to the emails, and the way we use Mailgun is just not a good fit for those kinds of situations.

Beware of Mailgun, it backfires.

May 29, 2020

Use Cases and Deployment Scope

Mailgun was used to deliver email for our coaching platform. We counted on Mailgun to deliver hundreds and sometimes thousands of emails between our coaches and clients, so no unsolicited email here.

Pros

When it worked, the mail generally got through.

Cons

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.

Likelihood to Recommend

If you are trying something out and want non-mission critical mail delivery in a free sample app, then Mailgun could be appropriate. If you are sending mission-critical email, look elsewhere.

Email service that just works

May 28, 2020

Use Cases and Deployment Scope

It's used for email forwarding, tracking delivery, and open rates by some teams. It's not used as our primary email integration. For that, we use Amazon SES. Wherever we have used Mailgun, it has not caused any problems and we have been using it for three years now, while we have seen issues with other providers.

Pros

Inbound Email forwarding
Outbound Email sending
Tracking

Cons

More intuitive UX

Likelihood to Recommend

Mailgun is well suited for personal projects, MVPs, and lightweight use cases. Haven't tested it under a high load.

Ease to use Mail API SaaS.

Pros

Easy to integrate with a development environment.
Reliable as a mail server
Can act as a test mail if you don't have one

Cons

No logging or debugging mechanism
Hard to track if an email is sent successfully.

Likelihood to Recommend

As far as I know, Mailgun is quite generous with the free plan so that you can use the free plan for testing.

May 8, 2019

Use Cases and Deployment Scope

Our company uses Mailgun because it solves our need for transactional emails. We decided to use them because of their 10,000 free emails a month, easy to use API, easy to integrate and send emails reliably. It is used mainly by our product development team, more specifically our backend Ruby on Rails (RoR) developer.

Pros

Mailgun ensures that emails from your website actually make it to their destination. With their free tier covering the first 10,000 emails, it's a free solution to a prominent issue: emails getting stuck in email filters or not making it at all.
Mailgun is easy to sign up for and easy to integrate into your site, especially if you are using WordPress.
Absolutely love the mail logs too - that's come in quite handy on many an occasion.

Cons

It's worth noting that everything that operates through Mailgun is through API, unlike something like SendGrid which offers a full dashboard alongside their API. This may or may not be an issue for some people.
Our biggest limitation with Mailgun is with our ERP system and how they only chose to provided limited support to the many features Mailgun offers.
Mailgun's analytics can be very confusing unless proper tagging is implemented on your emails.

Likelihood to Recommend

Mailgun's pay-as-you-go pricing structure is fantastic, especially if you don't need to send that much email. The pricing, including the free tier, is much more generous than what you can get with some pricier providers, like SendGrid. I mainly just use Mailgun as an SMTP server for web services, and the service has been set-up-and-forget, which is great because I never even have to log onto the Mailgun website and do any work. Mailing list support also looks great for rolling-your-own and not relying on more expensive mailing list services.

Shot Mailgun and Buried it alive for SendGrid

May 8, 2019

Use Cases and Deployment Scope

Our company started using Mailgun as our transactional email platform when I originally came into the CMO role at dinely. It was a few lines of code with some plain text emails that were being sent to our restaurants and users based on some basic user data such as sign up and password reset.

Pros

High Deliverability.
Easy integration with a few lines of code.
Low cost per email.
Good free tier.

Cons

No Marketing Emails. It's just transactional, but I like to have everything under one roof.
You have to hardcode HTML emails, as there's no nice design or editor.

Likelihood to Recommend

Mailgun is a good transactional email program. But for smaller teams that don't want to waste time hiring or writing more code than needs, there are better alternatives for them. But for the low cost and basic plain-text emails, it could work well for a company that doesn't worry about branding their emails and just needs the bare bones.
