The code I'm using looks just like so many examples
But "Web" is an undefined type.
Even ReSharper can't tell me where to find it.
Do I need another reference with a using or has 'Web' been renamed in v 9.9.0?
var myMessage = new SendGridMessage();
myMessage.AddTo(message.Destination);
myMessage.From = new EmailAddress("somebody#xyz.com", "Fff
Lll");
myMessage.Subject = message.Subject;
myMessage.PlainTextContent = message.Body;
myMessage.HtmlContent = message.Body;
var credentials = new NetworkCredential(
ConfigurationManager.AppSettings["mailAccount"],
ConfigurationManager.AppSettings["mailPassword"]
);
// Create a Web transport for sending email.
var transportWeb = new Web(credentials);
You are following the V2 api documentation which is now obsolete . You can use the V3 api SDK instead . The sample code is like below
var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
var client = new SendGridClient(apiKey);
var from = new EmailAddress("test#example.com", "Example User");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("test#example.com", "Example User");
var plainTextContent = "and easy to do anywhere, even with C#";
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);
you need to refer the below namespaces
using SendGrid;
using SendGrid.Helpers.Mail;
you can also send the mail without the mail helper class . Follow the below link for more usage and demo

I can send a simple email, I can also send emails using a specific template w/ the TemplateId like the example below, but
QUESTION - How do I send this template below and add or include handlebar data (ex. {"name":"Mike", "url":"some_url", "date":"04/18/2022})?
FYI - I can't find any doc that shows any C# examples. I did find this link to create a transactional template but it doesn't send the email. So not sure here if this is what I'm looking for...
var client = new SendGridClient(Options.SendGridKey);
var msg = new SendGridMessage() {
From = new EmailAddress(fromEmailAddress, fromEmailName),
Subject = subject,
PlainTextContent = message,
HtmlContent = message,
TemplateId = "d-30710e173a174ab58cc641nek3c980d4c"
};
var response = await client.SendEmailAsync(msg);
The solution is that you need to remove the PlainTextContent and HtmlContent properties to make use of the template. Also, you need to provide a dynamicTemplateData object that contains your placeholders.
Here are two code examples that send dynamic template emails with and without the helper class (search for dynamic_template_data and dynamicTemplateData). So the full snippet with the mail helper class would be:
var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
var client = new SendGridClient(apiKey);
var msg = new SendGridMessage();
msg.SetFrom(new EmailAddress("test#example.com", "Example User"));
msg.AddTo(new EmailAddress("test#example.com", "Example User"));
msg.SetTemplateId("d-d42b0eea09964d1ab957c18986c01828");
var dynamicTemplateData = new ExampleTemplateData
{
Subject = "Hi!",
Name = "Example User",
Location = new Location
{
City = "Birmingham",
Country = "United Kingdom"
}
};
msg.SetTemplateData(dynamicTemplateData);
var response = await client.SendEmailAsync(msg);
PS: Here is the general API documentation that explains the available properties.
I have a problem sending an email with SendGrid. I am getting this error:
Unknown HOST exception (api.sendgrid.com) in Visual Studio.
I am trying out SendGrid and followed their sample code:
using SendGrid;
using SendGrid.Helpers.Mail;
using System;
using System.Threading.Tasks;
namespace Example
{
internal class Example
{
private static void Main()
{
Execute().Wait();
}
static async Task Execute()
{
var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
var client = new SendGridClient(apiKey);
var from = new EmailAddress("test#example.com", "Example User");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("test#example.com", "Example User");
var plainTextContent = "and easy to do anywhere, even with C#";
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);
}
}
}
This produced this error:
Unknown HOST exception (api.sendgrid.com)
I tried to see if I can connect to SendGrid web and api subdomain by pinging it and realized that I was not connecting.
Now I am wondering how to allow my environment to connect to SendGrid API. See attachment for my ping result.
If you have faced this issue and solved it, please advice me how you did it.
Thank you.
I am using C#, 4.7.1 FW, and the SendGrid nuget.
I have been in contact with SG support and so far have not yet been directed to or figured out how to send a template. I have tried to use the native MailMessage, and also the SendGridMessage.
I have my template id specified and I keep running into problems where the email fails and I am told "Substitutions may not be used with dynamic templating"
Here is the latest snippet I am bashing my head against a brick wall over:
var apiKey = "snip";
var client = new SendGridClient(apiKey);
var from = new EmailAddress("from#domain.com", "display name");
var subject = "Sending an email template";
var to = new EmailAddress("me#domain.com", "To Name");
var plainTextContent = "";
var htmlContent = ""; // I read htmlContent needs to be blank?
var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
Personalization p = new Personalization
{
Substitutions = new Dictionary<string, string>()
};
p.Substitutions.Add("[eventname]", "test event"); // my template has 3 subs, this is one of them
p.Tos = new List<EmailAddress>();
p.Tos.Add(to);
msg.Personalizations.Add(p);
msg.SetTemplateId("snip");
var response = await client.SendEmailAsync(msg);
var stringResponse = response.Body.ReadAsStringAsync();
Response:
{"errors":[{"message":"Substitutions may not be used with dynamic templating","field":"personalizations.1.substitutions","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.personalizations.substitutions"}]}
I am this close to just reverting all of this to building my own HTML template and storing that in a database, pulling it and replacing the placeholders like [eventname] with values. This shouldn't be this hard.
is there something wrong with this code? I already put my email in my code but I don't get any email.
I have a hint that is it not working because I am using API key ID instead of API key because I can't see my API key because of its only show just once. if is that the reason why is this code not working. Is there no way to view your API key again?
public string SendEmailMain()
{
SendEmail().Wait();
}
static async Task SendEmail()
{
common com = new common();
var apiKey = com.sendGridAPI;
var client = new SendGridClient(apiKey);
var from = new EmailAddress("testmail#gmail.com", "test user");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("testemai#gmail.com", "teset user");
var plainTextContent = "and easy to do anywhere, even with C#";
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);
}
the code is working pretty well. The thing is i'm using the API key ID because instead of the API key that generated by sendgrid.
Please refer to this thread for more info
Error: The type 'MailAddress' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Net.Mail, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
var myMessage = new SendGrid.SendGridMessage();
myMessage.AddTo(model.To);
myMessage.From = new System.Net.Mail.MailAddress(model.From, model.Subject);
myMessage.Subject = model.Subject;
myMessage.Text = model.TextBody;
myMessage.Html = model.HtmlBody;
The From property of the SendGridMessage class is a type of EmailAddress class which is in Sendgrid.Helpers.Mail namespace . But your are assigning a different type here
myMessage.From = new System.Net.Mail.MailAddress(model.From, model.Subject);
I think you are using the incorrect nuget package for .net core . The correct updated nuget package for Sendgrid with V3 api which is compatible with .NET Core is available at the below link (v 9.9.0) .
https://www.nuget.org/packages/Sendgrid/
Check the sample code below to send email with V3 api using the MailHelper class
var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
var client = new SendGridClient(apiKey);
var from = new EmailAddress("test#example.com", "Example User");
var subject = "Sending with SendGrid is Fun";
var to = new EmailAddress("test#example.com", "Example User");
var plainTextContent = "and easy to do anywhere, even with C#";
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);
