A robust and flexible Go library for creating and sending emails with support for attachments, HTML content, and connection pooling.
Email is a Go library that provides a robust and flexible interface for creating and sending emails programmatically. It solves the problem of handling email composition, attachments, and SMTP sending in Go applications with a clean, human-friendly API. The library supports both text and HTML content, multiple recipient fields, and efficient connection pooling for high-volume email operations.
Go developers who need to integrate email functionality into their applications, particularly those building notification systems, marketing tools, or any backend service that requires programmatic email sending.
Developers choose this library because it offers a perfect balance between simplicity and flexibility, with a well-designed API that handles common email tasks easily while supporting advanced features like connection pooling and custom headers. It's specifically built for Go with performance and developer experience in mind.

The library offers a simple and clean interface, as shown in examples with straightforward struct initialization and method calls like NewEmail() and Send(), making email creation and sending easy.
Supports both plain text and HTML bodies in the same email, allowing for rich email content without extra libraries, as evidenced by the Text and HTML fields in the email struct.
Includes connection pooling via NewPool() for reusable SMTP connections, optimizing performance for high-volume email operations as demonstrated in the pool example.
Provides simple methods like AttachFile() to add files to emails, streamlining attachment management with minimal code, as shown in the README.
The library lacks a template engine for dynamic email content, requiring developers to handle templating separately with external libraries, which adds complexity for personalized emails.
Relies on external SMTP servers for sending, meaning additional setup and maintenance compared to cloud-based email services, as shown in the requirement for SMTP configuration in examples.
Version >1 mandates Go v1.5 or above, which can be a barrier for projects stuck on older Go versions, as noted in the installation section.
