Mailgun Alternatives & Competitors

Top Mailgun Alternatives: Which is the Right Email Delivery and Verification Platform?

If you've been using Mailgun for sending transactional emails, SMTP relays, or integrating email into your app or marketing stack, you know it’s a developer-friendly, highly customizable platform. It excels at high-volume sending, API access, and detailed deliverability features.

However, many teams are exploring alternatives to Mailgun due to factors such as pricing complexity, deliverability concerns, support issues, or the need for marketing-friendly features rather than developer-only tools.

If you’re looking for a Mailgun replacement that better aligns with your budget, marketing use case, or ease of use, you're in the right place. In this guide, we’ll look at some of the top Mailgun alternatives, such as SendGrid, Postmark, Brevo (formerly Sendinblue), Amazon SES, SparkPost, and Moosend.

Let’s walk through why people are switching to tools similar to Mailgun, compare their features, and help you pick a platform that fits your needs.

Why Are People Switching to Mailgun Alternatives?

While Mailgun remains a strong choice for many use cases, users often cite the following reasons for choosing a Mailgun substitute:

• Complex pricing for smaller senders: Many users find that once their email volume grows or they require premium features like dedicated IPs, deliverability consulting.
• Deliverability / shared-IP issues: Some users report reputation problems when sharing IPs or when other senders’ behavior affects deliverability.
• Limited marketing-automation features: Mailgun is very developer-centric (API, SMTP, logs), but if your focus is newsletters, drag-and-drop editors, and multi-channel, you might want a better marketing-oriented tool like Mailgun.
• Support or usability complaints: Feedback indicates that support can be slow or that setup is too technical for non-dev teams.
• Need for broader features beyond transactions: If you want to handle both transactional and large-scale marketing emails, or integrate SMS/chat, a platform with more bundled features may work better.
