An easy way to send emails with attachments

Send attachments

m := email.NewMessage("Hi", "this is the body")
m.From = "[email protected]"
m.To = []string{"[email protected]"}

err := m.Attach("picture.png")
if err != nil {
	log.Println(err)
}

err = email.Send("smtp.gmail.com:587", smtp.PlainAuth("", "user", "password", "smtp.gmail.com"), m)

Send unencrypted password

err = email.SendUnencrypted("mail.example.com:25", "user", "password", m)
