A Go client library for interacting with the Mailgun email API, enabling sending, validation, event tracking, and webhook handling.
mailgun-go is an official Go client library for the Mailgun email service API. It enables Go developers to programmatically send emails, validate addresses, track email events, and handle webhooks through a clean, idiomatic Go interface. The library solves the problem of integrating robust email functionality into Go applications without building low-level HTTP clients.
Go developers building applications that require email capabilities, such as transactional email systems, notification services, or marketing platforms. It's particularly useful for teams already using Mailgun who want native Go integration.
Developers choose mailgun-go because it's the official, maintained Go library for Mailgun with complete API coverage, proper Go conventions, and production-ready features like context support and webhook verification. It reduces boilerplate and provides type safety compared to generic HTTP clients.
Go library for the Mailgun API.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Covers the entire Mailgun API, including email sending, event polling, validation, webhooks, and templates, as shown in the comprehensive code examples for each feature.
Designed with Go best practices, featuring type-safe APIs, context support for timeouts and cancellation, and clean error handling, ensuring reliability in production.
Actively maintained by Mailgun with CI/CD pipelines, Godoc documentation, and detailed migration guides for major versions, reducing the risk of abandonment.
Includes built-in webhook signature verification and secure API key handling, as demonstrated in the webhook example, minimizing security risks in email processing.
Tightly coupled to Mailgun's API; switching to another email service would require significant code changes, as the library's interfaces are specific to Mailgun.
Running tests requires API keys and can incur real money, as noted in the README warning about MG_SPEND_MONEY, which may deter thorough testing in development.
Includes advanced features like event polling and template support that add complexity, making it overkill for applications that only need occasional email sending without tracking.
