Sending Email is a basic task of a web application for many purposes
like- Error logging, Reporting, Newsletters, and Performance alerting
as well as for many other reasons.
you have taken web space somewhere on a web server then you are
provided with the Email accounts and SMTP and POP services for sending
and receiving E-mails. Some times you don't have SMTP server accounts
and you may want to send email. Or Sometimes, for other reasons also
you may want to use third-party SMTP sever for sending E-mails .
Gmail is a good solution for this purpose. Gmail provides SMTP and POP access which can be utilized for sending and receiving E-mails.
Here in this tutorial we will be using a Gmail account for sending email by SMTP.
1. Gmail has a fixed
number of quota for sending emails per day, means you may not be able
to send unlimited number of e-mails using Gmail due to anti-spamming
2. You may not be able to send same e-mail to
unlimited number of people, because Gmail's anti-spamming engine
restricts for this too.
So, Gmail can be used for sending
limited number of e-mails daily to select people only. If you still
need to send numerous e-mails to numerous people you can register for a
Google Group account and can use that e-mail address to send email to
registered members of that group. I will come up with that tutorial in
Using the code
1. An active Gmail account is required to test this application.
2. Visual Studio 2005
Here we go:
Step 1: Create a new web application in visual studio and add a Web form to it.
Next add a Button to the form and double click this button to bring the
code for click event of this button in the code window. Copy paste the
following code to the click event.
2: Run the web application and click on the Button to send the mail.
Check the E-mail whether you get the mail successfully or not.
Note: Don't forget to replace the To and From fields as well as the correct password for successfully sending the mail.
string from = email@example.com;
string to = firstname.lastname@example.org
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();<o:p />
mail.From = new MailAddress(from, "One Ghost" , System.Text.Encoding.UTF8);<o:p />
mail.Subject = "This is a test mail" ;<o:p />
mail.SubjectEncoding = System.Text.Encoding.UTF8;<o:p />
mail.Body = "This is Email Body Text";<o:p />
mail.BodyEncoding = System.Text.Encoding.UTF8;<o:p />
mail.IsBodyHtml = true ;<o:p />
mail.Priority = MailPriority.High;<o:p />
SmtpClient client = new SmtpClient();<o:p />
client.Credentials = new System.Net.NetworkCredential(from, "Password");
client.Port = 587; <o:p />client.Host = "smtp.gmail.com";<o:p />
client.EnableSsl = true; try<o:p />
catch (Exception ex)<o:p />
Exception ex2 = ex;<o:p />
string errorMessage = string.Empty;<o:p />
while (ex2 != null)<o:p />
errorMessage += ex2.ToString();<o:p />
ex2 = ex2.InnerException;<o:p />
<o:p> </o:p> HttpContext.Current.Response.Write(errorMessage );<o:p />
} <pre />
Points of Interest
Some-times it takes 2-3 minutes or more to reach the mail to the destination server. So check after a while, if you do not get it soon.

I am a software architect by profession, innovator by nature and an artist from the inner essence.
I have been programing from my childhood days. I started my programing life in my high school days, in 6th grade when I was used to write a lot programs in BASIC language.
Then, I learnt Visual Basic-6 language and written hundreds of programs, varying from Graphics (including Direct-x, Open GL), Win 32 API, Database Application, Socket programing and Signaling.
Graphics was my then favorite field of interest. I wrote few award wining graphics applications, one called Magic Brush which won several national and international prizes and praise. Later I got fascinated towards web technologies that encouraged me to write an anti-spam software recognition engine called "Spamocide".
It was the journey of a hobbyist programer. Then, started my academic programing journey which continues. I love to program for research projects specially in the field of computer security, Internet, Ontology, Artificial Intelligence and many more.
In 2007 my software research project called ECIGS was among top 5 softwares in Microsoft Imagine Cup national finals.
