Mailchimp Transactional Email (Mandrill)

Any system that requires transactional email message functionality as an external service. The benefits of a well managed and vetted server to maintain reputation as well as being reliability is well worth the effort needed to integrate towards the API specs

Mailgun

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.

Pros

Mailchimp Transactional Email (Mandrill)

  • Mandrill is extremely reliable. We switched from using a platform that was very hit-or-miss, but we never had a single deliverability issue with Mandrill's transactional API. Every email was sent reliably and quickly.
  • Mandrill's reporting and debugging features made it easy to ensure that all our messages were getting delivered to the right place in a timely manner. In fact, Mandrill's tools were so robust that we used it as an end-around way of debugging another failing service we were using.
  • Mandrill is a very affordable add-on to an existing MailChimp account. Adding an extra layer of reliability was a no-brainer, and made the cost essentially negligible to our organization.

Mailgun

  • 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

Mailchimp Transactional Email (Mandrill)

  • The rate-limit system can be troubling. If you are switching providers and already have a large e-mail volume, you're going to want to transition slowly. The per-hour send limits are initially very low, and if you have any deliverability or complaint hiccups, they will plummet quickly. The Mandrill support staff is very helpful in this area - they will not (and claim that they can not) manipulate send limits for any account at any time for any reason.
  • Billing is combined in with a paid MailChimp subscription, which didn't used to be the case.
  • No free tier.

Mailgun

  • No built-in templating features (This was a bit sad after coming from Mandrill which excelled at this)
  • Dashboard UI (although easy to use) is a bit dated in appearance
  • Logs are cumbersome compared to Mandrill
  • Setting up TLD (top level domain) names (things like .online or .church) that are not common require an email to tech support (this is annoying)
  • Sometimes can be slow in delivery
  • Shared IP addresses can be SPAM filtered or delayed (requires an email to support to have a new one assigned - Note: this can be mitigated by buying a dedicated one for a monthly fee)

It could be more up-to-date and could offer some extra features that other competitors do like templating and better querying and filtering. As it is right now most things are easy to use but seem rather barebones next to Mandrill. The API is easy to implement thanks to the great documentation which is why I recommend Mailgun so often.

I haven't personally reached out to their support team, but the feedback I've heard from our tech support and engineering teams have been that their response to questions has often been they either are unsure or that Mandrill is what it is. For example, when our customers weren't able to see opens and clicks for all emails sent, and we reached out to their support, the response was it is what it is, and they'll send a notification to our app if they can.

You can't seem to get ANY support until you shell out hundreds of dollars per month. I even did this when we could not deliver mail with Mailgun, and the response was slow and inadequate. Nor would they refund my money. I'll never be a customer of Mailgun again.

Alternatives Considered

Mailchimp Transactional Email (Mandrill)

So we actually work with clients across all of the platforms listed above, but Mandrill has a huge ease of use bonus in its favor, especially when working with clients who are setting up a Cart Recovery style marketing campaign for the first time or are looking for a bit of a fire-and-forget setup. With more sophisticated clients (on the scale of global ecommerce companies), who have a larger subscriber/customer base and in-house design teams, we find that Mandrill usually isn't enough

Mailgun

MailGun is more expensive than SparkPost and about the same price-wise as SendGrid. MailGun had a notably easy set-up process, since they are the first SMTP service we signed up with, and their support has been very helpful in identifying deliverability issues, providing documentation on IP reputation management, and recommending best sending practices.

Return on Investment

Mailchimp Transactional Email (Mandrill)

  • It helped us to grow our customer database substantially in the last quarter.
  • Last week we reached 62% customer engagement in our campaign. This is very good customer engagement for our projects.
  • In the last quarter we achieved our target by 135%.

Mailgun

  • By not investing in our mail server, we have saved huge amount of money and time. For configuration and installation of an email server on Linux-based server, we would have to hire a network administrator.
  • If email delivery is an issue in a hosting provider, another solution is to switch the hosting. Fortunately with Mailgun, we didn't need to try different hosts and experiment which one works best for emails. We can stick to our existing web hosting provider and would not need to change it just for the sake of improving email deliverability.
  • The pricing of Mailgun is very cheap and straightforward. First 10K emails are free every month and that's a big advantage for our organization because our volume of emails is rarely more than 10K per month.
