Does not send email password recovery by Sendgrid

Question

I implemented a class for sending password recovery email, but the email is not sent.

Class code sends email:

public static Task EnviaEmail(string email, string assunto, string mensagem)
    {
        var MinhaMensagem = new SendGridMessage();
        MinhaMensagem.AddTo(email);
        MinhaMensagem.From = new MailAddress("meuemail", "meunome");
        MinhaMensagem.Subject = assunto;
        MinhaMensagem.Text = mensagem;
        MinhaMensagem.Html = mensagem;
        var credenciais = new NetworkCredential("meunomedeusuario", "minhasenha");
        var transporteWeb = new Web(credenciais);

        if(transporteWeb != null)
        {
            return transporteWeb.DeliverAsync(MinhaMensagem);
        }
        else
        {
            return Task.FromResult(0);
        }
    }
}

This version of your code does not work with credentials. Instead of passing user and password (as in the old method), directly pass the Key API.

Also try to implement this other example, more oriented to the new Sendgrid service architecture:

    public static Task EnviaEmail(string email, string assunto, string mensagem)
    {
        string apiKey = ConfigurationManager.AppSettings['SendGridApiKey'].ToString();
        dynamic sg = new SendGridAPIClient(apiKey);

        Email from = new Email("[email protected]");
        Email to = new Email(email);
        Content content = new Content("text/plain", mensagem);
        Mail mail = new Mail(from, assunto, to, content);

        dynamic response = await sg.client.mail.send.post(requestBody: mail.Get());
    }
