Sendgrid not sending email in an on demand azure webjob running as console application - azure

Question

I have an on-demand azure webjob running as a console application.
Objective is send emails to customers.
Issue is it does not send emails.
My code is heavily lifted from msdn section How to: Send an Email. Following is my code snippet.
class Program
{
static void Main(string[] args)
{
Execute(Environment.GetEnvironmentVariable("WEBJOBS_COMMAND_ARGUMENTS")).Wait();
}
static async Task Execute(string email)
{
DeserializedCustomer customer = JsonConvert.DeserializeObject<DeserializedCustomer>(email);
var apiKey = Environment.GetEnvironmentVariable("SENDGRID_APIKEY");
var client = new SendGridClient(apiKey);
SendGridMessage msg = new SendGridMessage()
{
From = new EmailAddress(customer.Email, "From Email"),
Subject = $"Inquiry by - {customer.FirstName} {customer.LastName}",
PlainTextContent = customer.Comments + Environment.NewLine + $"Phone : {customer.Phone}",
};
msg.AddTo(new EmailAddress(ToMail, ToMailName));
if (!String.IsNullOrWhiteSpace(customer.Attachment))
{
List<Attachment> attachments = new List<Attachment>()
{
new Attachment()
{
Content = customer.Attachment,
Type = customer.AttachmentType,
Filename = customer.AttachmentFileName,
Disposition = "inline",
ContentId = customer.AttachmentFileName + Guid.NewGuid()
}
};
msg.Attachments = attachments;
}
await client.SendEmailAsync(msg);
}
}
Searching I found an SO post where giving time to sendgrid to send email in a console application
Adding time did not help either.
If there are some quirkiness about sending emails from azure webjobs running as console applications then I'm unaware.
Searching further I found this SO post where they successfully tested sending emails in console application so I thought it might help but it did not send emails.
All the above examples are more than a year old and none of them work currently.
I tried using an earlier version of SendGrid library but I am stuck on
var transportWeb = new Web(credentials);
transportWeb.DeliverAsync(myMessage);
as SendGrid library has been updated.
On github I found this which clearly states that console apps only work with transportWeb.DeliverAsync(myMessage).Wait
therefore I am trying with transportWeb.
Is there an amalgamation of azure with on demand webjob running as console application?
Can anyone help?
Update
After Randy Minder's help I updated the code to the following
static async Task Execute(string email)
{
try
{
DeserializedCustomer customer = new DeserializedCustomer();
customer = JsonConvert.DeserializeObject<DeserializedCustomer>(email);
Console.WriteLine(customer);
SendGridMessage msg = new SendGridMessage();
msg.From = new MailAddress(customer.EmailAddress, "From Email");
msg.Subject = $"Inquiry by - {customer.FirstName} {customer.LastName}";
msg.Text = customer.Comments + Environment.NewLine + $"Phone : {customer.Phone}";
msg.AddTo(ToMail);
// Create a network credentials object
var credentials = new NetworkCredential(Environment.GetEnvironmentVariable("UserName"), Environment.GetEnvironmentVariable("Password"));
var transportWeb = new SendGrid.Web(credentials);
transportWeb.DeliverAsync(msg).Wait();
}
catch (Exception ex)
{
DateTime now = DateTime.Now;
Trace.TraceError($"{now.ToLongDateString()} {now.ToLongTimeString()}" + Environment.NewLine + new ExceptionSerializer(ex));
}
}
I'm using SendGrid 6.1.0
<package id="Sendgrid" version="6.1.0" targetFramework="net47" />
I do not get any exception and my webjob runs to success

However I do not get any email

Answer 1

When attempting to send an email via SendGrid in a console app, you have to do it a bit differently. Here is a method I have that works in a console app:
/// <summary>
/// Send the email async in a console app.
/// </summary>
public async Task SendAsync()
{
// Create a network credentials object
var credentials = new NetworkCredential(azureUserName, azurePassword);
// Create an Web transport for sending the email
var transportWeb = new Web(credentials);
transportWeb.DeliverAsync(this._email).Wait();
}
This is what I use in a non-console app:
/// <summary>
/// Send the email async in backend or MVC code.
/// </summary>
public async Task SendAsync()
{
// Create a network credentials object
var credentials = new NetworkCredential(azureUserName, azurePassword);
// Create an Web transport for sending the email
var transportWeb = new Web(credentials);
await transportWeb.DeliverAsync(this._email).ConfigureAwait(false);
}
The actual email object is contained in this._email.

According to your description, I have also create a test demo on my side, it works well. I used the sendgird SDK is 9.90.
The details codes is like as below:
class Program
{
static void Main(string[] args)
{
string serializedEmail = args[0];
Console.WriteLine($"SerializedEmail - {serializedEmail}");
Customer customer = JsonConvert.DeserializeObject<Customer>(args[0]);
//Customer customer = new Customer() { Name = "aaaa" };
Execute(customer).Wait();
Console.WriteLine(customer.Name);
Console.ReadLine();
}
static async Task Execute(Customer customer)
{
var client = new SendGridClient("apikey");
var from = new EmailAddress("sendgird#xxxxxx.com", "Example User");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("sendgird#xxxxxxx.com", "Example User");
var plainTextContent = $"Name : {customer.Name}";
var htmlContent = "<strong>and easy to do anywhere, even with C#</strong>";
var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
var response = await client.SendEmailAsync(msg);
}
}
public class Customer
{
public string Name { get; set; }
}
However I do not get any email
I suggest you could firstly access this url to check the sendgird has already send the email to right email address.
The result is like this:
