## What it is
A Go library for composing and sending email over SMTP with a simple, human-friendly API. It supports text and HTML bodies, attachments, custom headers, read receipts, and a pool of reusable SMTP connections.

## Use cases
- send email from a Go application via SMTP
- send HTML and plain-text emails with attachments
- send transactional email through Gmail SMTP
- build a pool of reusable SMTP connections for high-throughput sending
- parse an email from an io.Reader

## When to choose
- you need a lightweight, dependency-free way to send email in Go
- you want simple struct-based email composition with attachments and headers
- you need connection pooling for concurrent SMTP sending

## When to avoid
- you need an email-sending service abstraction with providers like SendGrid or SES
- you need full MIME parsing of complex inbound email
- your project requires a library under very active development

## Facets
- artifact type: library
- maturity: maintenance
- function: email, http-client
- domain: email, backend, developer-tools
- platform: go, cross-platform
- tags: smtp, mime, attachments, connection-pool
