Sending simple email on Azure with Sendgrid

Question

I am trying to send email using SendGrid on Azure. I followed these instructions: https://learn.microsoft.com/tr-tr/azure/sendgrid-dotnet-how-to-send-email ; but it doesn't seem to work. . Sending via smtp works though.

using System;
using System.Threading.Tasks;
using SendGrid;
using SendGrid.Helpers.Mail;

namespace Example
{
    internal class Example
    {
        private static void Main()
        {
            Execute().Wait();
        }

        static async Task Execute()
        {
            var apiKey = System.Environment.GetEnvironmentVariable("SENDGRID_APIKEY");
            var client = new SendGridClient(apiKey);
            var msg = new SendGridMessage()
            {
                From = new EmailAddress("from@hotmail.com", "DX Team"),
                Subject = "Hello World from the SendGrid CSharp SDK!",
                PlainTextContent = "Hello, Email!",
                HtmlContent = "<strong>Hello, Email!</strong>"
            };
            msg.AddTo(new EmailAddress("to@gmail.com", "Test User"));
            var response = await client.SendEmailAsync(msg);
        }
    }
}

According to your code sample, it would run well while you do not receive any email.

So pay attention to some points as below:

1.When you create api key, make sure that you choose the Full Access. 2.You use Gmail to receive email, so set "Allow less secure apps:ON". 3.Check the response, if the StatusCode is Accepted it means it send email successfully. Then test agian, and it may work well.

Also, you want to make an function which is send email every 15 minutes.

You could refer to the code as below, I create azure function in v1.

public static void Run([TimerTrigger("0 */15 * * * *")]TimerInfo myTimer, [SendGrid(ApiKey = "sendgridkey")] out SendGridMessage message, TraceWriter log)
        {
            log.Info($"C# Timer trigger function executed at: {DateTime.Now}");
            message = new SendGridMessage();
            message.AddTo("testto@gmail.com");
            message.AddContent("text/html", "Test body");
            message.SetFrom(new EmailAddress("testfrom@gmail.com"));
            message.SetSubject("Subject");

        }
