So, you need the right tools to get the job done. 

While doing that, the first thing you should think about is your email deliverability tool. Mailgun is a popular choice for shipping emails to subscribers’ inboxes. But is it the only option out there? Definitely, no.

Here is everything you need to know about Mailgun and its top 6 alternatives.



What is Mailgun?

Mailgun is an email delivery platform that specializes in sending and tracking your marketing and transactional emails.



It supports its users with

  • Email APIs to integrate into your application
  • Inbound email management for responding quickly to leads
  • Cloud-based SMTP services for reliable email delivery
  • Detailed analytics for hourly monitoring and tracking
  • Send time optimization to get optimum results

Apart from this, it has Mailjet in its arsenal as part of the 2019 acquisition. It allows users to improve their email quality with better and more appealing templates. 



What Makes a Mailgun So Popular?

No one wants to spend their money and time on email marketing only to get blocked or marked as spam. Good email deliverability gets you the prime spot in the subscriber’s mailbox, but the real benefits go beyond.

1. Wide Option For Integrations

Mailgun supports integrations with a wide range of third-party products. Some of the popular ones are Amazon, Drupal, ActiveCampaign, and Dropbox.

It allows its users to create a seamless solution for optimal performance.

2. Ease of Creating Marketing Emails

Mailgun lets its user design responsive and aesthetic emails with its vast template library. The simple drag-and-drop feature allows even non-techy users to create beautiful emails that get the desired responses.

You can even segment and A/B test your emails to drive engagement and conversions.

3. Bulk Email Validator

No matter how well-curated your subscriber list is, a few bad addresses are unavoidable. But to prevent this from impacting delivery performance, Mailgun offers a bulk email address validator.

It cleans the list of invalid addresses containing syntax errors, typos, or incomplete details.

4. Send Time Optimization

Mailgun takes the guesswork out of the email send time. It monitors the reader’s activity to suggest the best send time for maximum conversions.

It improves engagement as the right message goes to the subscribers at the right time.




The Flip Side of Mailgun

1. Unexceptional Delivery Rate

Mailgun has an average delivery rate of 97%, which isn’t impressive considering the industry standard.

It can be a serious concern for enterprise businesses that can’t afford to lose any single lead.

2. Nothing to Handle IP Blacklisting

Mailgun offers a pool of dedicated and shared IPs. But it doesn’t support the management of IP if it is blacklisted.

It becomes an unnecessary hassle where one will have to constantly monitor and take corrective actions in case an IP is blocked.

3. No Download Option For Logs

The logs are available for only a limited time of 30 days, and the users can’t even download them.

It can bring down your analysis strategy and affect your email marketing plans.



Mailgun- Pricing & Plan

Mailgun works on a pay-as-you-grow basis, depending on the email volume and other marketing features.

The plans start at $35 a month with 50k emails and go up to $90 a month with 100k emails.



It also offers a monthly trial version with 5k free emails and $1 for the following 1k emails. You can get a custom plan if your email volume is high.



When Should You Look For Alternatives?

1. If You Prefer Prompt Support

Mailgun is not known for its support services. So, if you are looking for an email deliverability tool that assists you with troubleshooting and best practices, then maybe you should consider other options in the industry.

2. Better Email Deliverability Rate

Mailgun faces a big issue while delivering emails to Outlook and Hotmail, where most of the emails are marked as spam. It restricts your outreach and doesn’t deliver the expected results. 

Overall, Mailgun claims a 97% email delivery rate which is less compared to its competitors.

3. Expensive Player in the Market

It may not be the best option for growing businesses considering the price plans. There are alternatives in the market offering more at much lesser.
