Are you looking for an alternative tool to Mailgun?

Mailgun isn’t everyone’s cup of tea. I know both Capterra and G2 Crowd have given them 4.5/5 and 4.4/5 ratings respectively. But Trust Pilot has rated it at 3.7/5 while Crozdesk has them at 3.2/5.

That’s how I understood that all the happy Mailgun reviews might be partially biased. I did a bit of research and discovered that Mailgun alternatives have a monthly search volume of 720. Meaning, 720 people every month go online to look for Mailgun alternatives.

At the beginning of 2020, they stopped their forever free plan and most of the people enrolled had to look for cheaper and more functional alternatives.

Starting from their user interface, it’s frustrating if you’re not tech-savvy or a developer. For this reason, you’d expect them to have a highly responsive support system but you’re stuck with their slow ticket system.

I also discovered that Mailgun has an issue when it comes to email deliverability. Yes, you’re able to send bulk emails but sometimes they go straight into the spam folder instead of the inbox. Upon trying to get to the root of this issue, I found that Mailgun gives you blacklisted IPs.

Honestly, who does that?

To get yourself a Mailgun dedicated IP you’ve got to cough some good moolah. As if that’s not enough, their reports suck. Compared to Sendinblue, they are weak and take a while to load. And when they finally load, you’re not able to see it all at a glance.

I believe these are sturdy enough reasons to go hunting for a Mailgun alternative.

The whole process of looking for an alternative can be overwhelming. We have narrowed it down for you to our 5 top options. They all offer arguably better prices for more functional features.

Let’s dig in.

If you’re in a hurry and you need a quick summary, here are the five tools that we’ll look into in detail.

Top 5 Mailgun Alternatives


SendGrid logo

This is one of the popular SMTP services that hosts giants like Airbnb, Spotify, LinkedIn, and Uber.

Unlike Mailgun that has email deliverability issues, SendGrid’s main selling point is their A1 deliverability. And the million-dollar corporations can vouch for them.

When it comes to data protection and security measures, SendGrid is top-rated with a SOC 2 Type II certification. No need to worry about the safety of your business emails as all data is encrypted.

SendGrid contact management

In all honesty, it’s one of the most powerful solutions for sending automated eCommerce transactional emails at a scale.

Also, they have quite an impressive API integration as it was developed to work with other applications in the market.

Key Features

  • Sending bulk email campaigns with ease and still maintain high deliverability. Thanks to their email spam testing, dedicated IP, and email validation. These integrated email tests will show you invalid emails, spammy content, and broken links.

It is one of the easiest to use as a Mailgun alternative. Sendinblue is super user-friendly so no hectic steps to follow. Unlike Mailgun, the interface is well organized, modern, and you can see everything you need at a glance.

Also, they take care of all aspects of your marketing. You can refer to it as the cheaper MailChimp only that it comes with more features.

You don’t have to go on Facebook to track the performance as Sendinblue gives you all the metrics you need to optimize your campaigns. You also get to create retargeting campaigns.

SendPulse automation

No wonder they got the attention of large organizations like PWC, Radisson Blu Hotels, and Polish Airlines.

Plus their deliverability is good since they use SPF and DKIM verifications. And they vet every campaign before it goes out. As a result, their emails rarely go into the spam folder, unlike Mailgun.

Mailjet newsletter
