)

var sender mail.Sender

func init() {
	APIKey := envy.Get("SENDGRID_API_KEY", "")

func main() {
	APIKey := envy.Get("SENDGRID_API_KEY", "")
    sender = ssender.NewSendgridSender(APIKey)

	m := mail.NewMessage()
    ...
    ssender.SetCustomArgs(m, ssender.CustomArgs{
        "custom_arg_0": "custom_value_0",
