Send Email from your GMAIL account using ASP.Net and C#

Send email using Gmail account

Download Sample

You can use your gmail account to send emails from ASP.Net and C#, using SMTP. You need to set SSL credentials. This is not straight forward like a simple SMTP email. After searching for long hours I was able to find a solution. Use following class to send emails using your GMAIL account.

Please supply your gmail user name and password in following class where needed.

using System.Web.Mail;
using System;
public class MailSender
 public static bool SendEmail(
 string pGmailEmail, 
 string pGmailPassword, 
 string pTo, 
 string pSubject,
 string pBody, 
 System.Web.Mail.MailFormat pFormat,
 string pAttachmentPath)
 System.Web.Mail.MailMessage myMail = new System.Web.Mail.MailMessage();
 //sendusing: cdoSendUsingPort, value 2, for sending the message using 
 //the network.

 //smtpauthenticate: Specifies the mechanism used when authenticating 
 //to an SMTP 
 //service over the network. Possible values are:
 //- cdoAnonymous, value 0. Do not authenticate.
 //- cdoBasic, value 1. Use basic clear-text authentication. 
 //When using this option you have to provide the user name and password 
 //through the sendusername and sendpassword fields.
 //- cdoNTLM, value 2. The current process security context is used to 
 // authenticate with the service.
 //Use 0 for anonymous
 myMail.From = pGmailEmail;
 myMail.To = pTo;
 myMail.Subject = pSubject;
 myMail.BodyFormat = pFormat;
 myMail.Body = pBody;
 if (pAttachmentPath.Trim() != "")
 MailAttachment MyAttachment = 
 new MailAttachment(pAttachmentPath);
 myMail.Priority = System.Web.Mail.MailPriority.High;

 System.Web.Mail.SmtpMail.SmtpServer = "";
 return true;
 catch (Exception ex)

Example usage of this class,

                             "to_email @", 
                             "This is email subject" , 
                             "This is email body", 
                             "Physical path to your Attachment")

Note: If you do not want to attach a file with email, supply blank string as "".

Hi Shabdar,

I am new to ASP.Net developement and I want to use my gmail account when sending password retrieval emails. I think the standard controls that visual web developer 2008 provide are really neat but I cant get the app to send the mail via gmail's SMTP.

How should i use your code in such a way that will allow me to send the mails that the controls generate via gmails smtp?

Hi Shabdar,

I want to send email using my gmail account from my laptop. It is connected to the internet, but there is no SMTP service running on it. My question is:
Do i need SMTP service to be running on my laptop to be able to use your code to send email (via gmail account) ?

No, you don't need SMTP service running on your laptop/computer/server.
