## Ejemplo
|
|
|
|
```go
|
|
msg := EmailBuildHTML("alice@example.com", []string{"bob@example.com"}, "Informe", "<p>Ver adjunto</p>")
|
|
att := EmailAttachment{Filename: "report.pdf", ContentType: "application/pdf", Data: pdfBytes}
|
|
msg2 := EmailWithAttachment(msg, att)
|
|
// len(msg.Attachments) == 0 (original no mutado)
|
|
// len(msg2.Attachments) == 1
|
|
```

## Notas
|
|
|
|
Funcion pura. Implementa el patron immutable builder — cada llamada retorna un nuevo `EmailMessage` con copia profunda de todos los slices y mapas. Se puede encadenar varias veces para agregar multiples adjuntos.
