Mailgun

Great package!

The only problem I am running into, and I'm sure it's me, is that when I try to send through mailgun, my HTML message gets rendered in the mail client with the wrong content type (text/plain).

Below is the code used to send, and below is the sample email (raw) received.

That is, the message displayed in the browser appears to have the correct payload, but the user gets to read raw html rather than a nicely formatted message.

Any idea what I'm doing wrong?

cfg := mail.Config{
    URL:         "https://api.mailgun.net/",
    APIKey:      "someapikey",
    FromAddress: mailMessage.FromAddress,
    FromName:    mailMessage.FromName,
    Domain:      "mg.mydomain.com",
}

driver, err := mail.NewClient(mail.MailGun, cfg)
    if err != nil {
    fmt.Println(err)
}

var toSlice []string
toSlice = append(toSlice, mailMessage.ToAddress)

formattedMessage = "<h1>Hello, world</h1>"
plainText := "Hello, world"

tx := &mail.Transmission{
    Recipients: toSlice,
    Subject:    mailMessage.Subject,
    HTML:       formattedMessage,
    PlainText: plainText,
}

rs, err := driver.Send(tx)
    if err != nil {
    fmt.Println(err)
}

fmt.Println(rs)

And here is the resulting message:
