Amazon SES vs Mailgun: Features, Pricing and User Reviews 2026

Amazon SES is a service that sends and receives emails for your business through the internet. Instead of running your own email server, you use Amazon's system to handle everything. You can send marketing campaigns, order updates, password resets, or any other emails your application needs.

The service runs on Amazon's reliable network of data centers around the world. This means your emails get delivered quickly and reach inboxes instead of spam folders. Amazon SES checks your sender reputation, helps you follow email best practices, and provides reports showing how your emails perform.

You access Amazon SES through simple tools like web APIs, standard email protocols, or the AWS management screen. It takes minutes to start sending emails once your account is set up and verified.

Mailgun is a cloud-based email delivery service designed specifically for developers and businesses who need to send emails programmatically through their applications. Think of it as the engine that powers email functionality in websites and apps - from simple contact forms to complex automated email workflows.

The platform offers both RESTful APIs and SMTP relay services, giving developers flexibility in how they integrate email capabilities. Unlike traditional email marketing platforms with drag-and-drop editors, Mailgun focuses on programmatic email sending with features like real-time tracking, webhook notifications, and detailed delivery analytics.

What sets Mailgun apart is its focus on deliverability and developer experience. The service handles technical complexities like IP reputation management, email authentication, and spam compliance, while providing simple APIs that work with virtually any programming language including Python, PHP, Java, Ruby, and Node.js.
