Before exploring each of these transactional SMTP services in detail, allow me to briefly talk about Mailgun.

What Is Mailgun?

Mailgun is a cloud-based SMTP service provider that specializes in sending and delivering transactional emails.

The company was founded in 2010 and since then it has grown to become a renowned SMTP service.

Mailgun Homepage

In addition to this, almost after a decade in 2019, Mailgun acquired Mailjet, yet another famous email marketing service. Although, unlike Mailgun, Mailjet is a complete email marketing suite that allows you to create & send promotional email campaigns and also grants access to the marketing automation feature.

It’s safe to say that with this acquisition, Mailgun could have solved your promotional and transactional email requirements.

Now you’d be wondering as to…

Who Uses Mailgun?

Mailgun clearly mentions it on their homepage that it offers SMTP service and email APIs for developers and businesses.

If you have a website that drives actions or transactions from your audience or an app that also initiates different actions from its users, Mailgun is a good fit for it.

You’d be amazed to know that as of now, Mailgun has a user base of over 225,000 clients.

Some of the most notable Mailgun customers include Dell, NHL, Lyft, Microsoft, etc.

That being said, you must be thinking if Mailgun is so good, why would anyone look for its alternatives?

Here’s a brief rundown of…

Why You Should Look For Mailgun Alternatives? (Cons Of Mailgun)

I am quite sure that if you are already using Mailgun, you must be having some personal reasons as well that are enforcing you to switch.

Apart from this, here are a few drawbacks of using Mailgun –

  • Mailgun is suitable only for sending transactional email campaigns. You cannot send promotional email campaigns with it. Although to send promotional campaigns, you’d have to rely on Mailjet.
  • Since it is recommended for developers only, we can conclude that It is very difficult to set up and begin with.
  • You don’t have the provision to create email templates. For this, you’d either have to rely on third-party email builders or create HTML templates within your software/site.
  • There are some alternatives to Mailgun that offer better email deliverability. In addition to this, there aren’t any conclusive deliverability reports of Mailgun over the Internet.
  • Unlike its alternatives, Mailgun does not have a forever free plan. There’s only a “pay as you grow” plan that offers free 5,000 emails/month for the first three months. After that, you’d have to pay to continue email sending.
  • Mailgun is relatively expensive than most of its alternatives. Over the years, Mailgun introduced new features like email validation and due to this, the overall cost of using the service also increased.

I hope by now, you must be fully convinced that finding the best Mailgun alternative is the only logical option left.

Stand Out Features You Must Look In Mailgun Alternatives

Before you explore all the Mailgun competitors, here’s a checklist of features you must look for in the service provider.

  • Simple To Set Up – First and foremost, the ideal replacement must be easy to configure and requires just a few basic steps to set up.
  • Better & Faster Email Delivery – The alternative service must be able to send transactional emails instantly and automatically. In addition to this, it is of utmost importance that the emails land in the inbox.
  • Suppression Management – In order to be compliant with the CAN-SPAM law, the chosen software must be able to manage suppression email lists. In simple terms, the software must handle bounce (hard & soft), unsubscribes, and spam requests efficiently.
  • Prompt Customer Support – An ideal replacement must be backed by a prompt 24*7 customer support to help you with your queries or technical issues.
  • Free Plan – It is important that the alternative software must offer a generous free plan to thoroughly test out the application. The free plan also proves to be a boon to new businesses and startups.
  • Cheaper Pricing Structure – It is of great importance that the software that you pick as an alternative is affordable. After all, who wants to burn a hole in their pocket.

Keeping the above-mentioned points in mind, I have explored some of the top Mailgun alternatives.

Let’s talk about them in detail one at a time…

1. Sendinblue

One of the most prolific names in the email marketing category is Sendinblue. The software rose to fame through its email marketing suite and also because of its SMTP servers. You’d be also surprised to know that it now offers multiple marketing suites like live chat, CRM, SMS marketing, automation, etc. in just one software.

Although, the stuff that makes Sendinblue the best Mailgun alternative is its transactional SMTP servers and email API. Rest assured, many bloggers, eCommerce sites, business owners, software developers, etc. use Sendinblue SMTP to send transactional emails for their websites, apps, or software.

Sendinblue - Best Mailgun Alternative

Features That Make Sendinblue An Ideal Mailgun Alternative

  • Sendinblue offers plenty of simple ways to get started and send transactional emails. It includes SMTP relays, email API, WordPress plugin, eCommerce plugin, and marketing automation.

Unlike Mailgun, Sendinblue offers a forever free plan that allows you to send 9,000 emails in a month. However, there’s a 300 emails/day sending limit. Despite this, Sendinblue can be considered as a Mailgun free alternative.

Apart from this, you can remove the daily email sending restrictions and get a larger email sending quota by subscribing to its premium plans.

Sendinblue Pricing
  • Free – 9,000 emails in a month with 300 emails/day sending limit.
  • Lite – The Lite plan offers multiple sub-tiers that start at $25/month and allows you to send 10,000 emails/month. The last tier in the Lite plan costs $99/month and permits you to send 100,000 emails/month.
  • Premium – Just like other plans, the Premium plan also offers multiple pricing tiers and grants access to advanced tools. The Premium plan starts at $65/month for 20,000 emails/month and goes up to $599/month for 1,000,000 emails/month.
  • Enterprise – If you have higher emailing needs, more than 1 million emails to be exact, you’d have to contact the sales team for custom pricing.

Please bear in mind that each plan unlocks multiple advanced features as you move up the order. To understand the pricing in detail, I’d recommend you to check the Sendinblue pricing page.

MailerSend is probably the newest email marketing software that specializes in sending transactional emails. Despite being a new addition to the list of email marketing software, you can trust and rely on its efficiency as it has been created by the team of MailerLite.

As I have said, the software has been developed dedicatedly to cater to and furnish transactional email needs. To help you quickly get started, MailerSend offers plenty of simple ways to integrate it with your software or website. These include SMTP relay, API, and webhooks.

Another awesome software that captured the attention of a lot of email marketers and businesses in the past couple of years is SendPulse. Simply because the software improved its emailing performance and also evolved itself into a multi-channel marketing suite.

Among its array of features and marketing modules, the stuff that stands out is its SMTP relay and API.

4. Pepipost

Pepipost is yet another one of the best Mailgun alternatives that offer SMTP servers and email APIs for sending transactional as well as promotional email campaigns. It can be easily integrated with any software or open-source email marketing software.

That being said, Pepipost is almost similar to Mailgun as you’d need an email template designer to create email templates. Apart from this, Pepipost gives a tough competition to Mailgun in terms of email delivery and pricing plans.

5. SMTP2GO

SMTP2GO is one of the most under-rated and under-appreciated SMTP service providers available in the market. Based out of New Zealand, SMTP2GO has certainly caught the attention of some of the email marketers (also me) with its performance. And hence, it is logical to mention SMTP2GO as one of the Mailgun competitors.

Unlike Mailgun, SMTP2GO is well efficient to send transactional as well as promotional email campaigns. Thanks to its relatively smaller clientele, the team at SMTP2GO has managed to keep the high email delivery.

To start things off, SendGrid offers a forever free plan that allows you to send 100 emails every day. The free plan grants access to all the essential tools.
