## Ejemplo
```go
msg := EmailBuildHTML(
"alice@example.com",
[]string{"bob@example.com", "carol@example.com"},
"Reporte mensual",
"<h1>Hola</h1><p>Ver adjunto.</p>",
)
// msg.BodyHTML = "<h1>Hola</h1><p>Ver adjunto.</p>"
// msg.BodyText = ""
```
## Notas
Funcion pura. Copia el slice `to` para evitar aliasing con el caller. Para anadir adjuntos usar `EmailWithAttachment`. Para texto plano usar `EmailBuildText`.
