Introduction: Hello everybody, in this article i will explain that how we can create and send “newsletter” in asp.net. This is very helpful article for every .net developer
Implementation: Create a page namaed newletter.aspx. Place a fileuploader named attach_file, label named lbl_msg and a button named send. Below I am giving complete .aspx code and .aspx.cs page’s code.
Code for .aspx page:
<head id="Head1" runat="server">
<title>Newslatter</title>
</head>
<body>
<form id="form1" runat="server">
<div align="center" style="margin-top:100px">
<asp:FileUpload ID="attach_file" runat="server" />
<asp:label ID="lbl_msg" runat="server" text=""></asp:label>
<br />
<br />
<asp:Button ID="send" runat="server" onclick="send_Click" Text="send" />
</div>
</form>
</body>
Code for aspx.cs page:

using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;

using System.Net.Mail;
public partial class newsletter : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
}
}
// here am creating a function named snd_mail()
public void snd_mail()
{
try
{
// here m using sbodyas StringBuilder class
StringBuilder sbody = new StringBuilder();
// For sending the newsletter in the asp.net we need the complete structure of a newsletter in html.here i am using a sample structute
// of a newsletter in html.
// here i m filling the stringbuilder class sbody with the complete html. You can also send image through the newsletter. To send image there is
// need for the complte server's address of the image. like see below
sbody.Append("<img src=http://a1.twimg.com/profile_images/1427057726/asp_image.jpg/>");
sbody.Append("<table align=center border=2 cellspacing=6 cellpadding=9 width=640 <tr> <td bgcolor=cornsilk> <table bgcolor=gold width=90% align=center><tr><td align=center><img src=http://a1.twimg.com/profile_images/1427057726/asp_image.jpg/></td><tr/><tr><td align=center> ");
sbody.Append("<b><font size=5 color=brown> Employee Portal</font></br>");
sbody.Append("<font size=2 color=black> " + DateTime.Now + " </font>");
sbody.Append("</b> </td></tr></table> </br> <br>");
sbody.Append("<table bgcolor=gold cellpadding=0 cellspacing=0><tr><td><font size=4 color=brown>Deatil of Your registration for Glotera Portal</font></td></tr></table>");
sbody.Append("</br> Feature Article Related Articles <br> What's New</br> Guest Article</br>Classifieds</br> Feedback </br></br></br> ");
sbody.Append("<table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td><font size=4 color=brown>Feature Article</font>");
sbody.Append("</td></tr></table> </br> blah blah goes here - usually more than one ?");
sbody.Append("</br></br></br> <table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td> <font size=4 color=brown>What's New</font>");
sbody.Append("</td></tr></table> </br> blank if no new news - but it could also contain a link to the current meeting minutes - depends on the type of web site.</br></br></br>");
sbody.Append("<table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td><font size=4 color=brown>Guest Article</font>");
sbody.Append("</td></tr></table> </br> blank if no article for this period </br></br></br> <table bgcolor=gold cellpadding=0 cellspacing=0>");
sbody.Append("<tr><td> <font size=4 color=brown>Classified (or Sponsors)</font> </td></tr></table></br> Forum Link (to the onsite forum)</br> Forum would contain Classified Section (and Sponsors Information for some types of web sites). <br> i.e. this section could be a link to an online Forum - or the info could be included in this section of the newsletter.");
sbody.Append("</br></br></br> <table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td> <font size=4 color=brown>Feedback Form</font>");
sbody.Append("</td></tr></table></br> A link to the Feedback Forum Section.</br> i.e. this section could be a link to an online Forum - or a form could be embedded in the online page - or it could just be an email link (mailto).");
sbody.Append("</br></br></br> <table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td><font size=4 color=brown>Subscription and Archive</font> </td></tr></table> </br> How to Subscribe (could be link to 'tell-a-friend' form)</br>");
sbody.Append("How to Unsubscribe</br> Link to Newsletter Archives </br></br></br> <table bgcolor=gold cellpadding=0 cellspacing=0> <tr><td>");
sbody.Append("<font size=4 color=brown>About:</font> 'Newsletter Site Name Here' </td></tr></table> </br> Your Signature File or Name</br>");
sbody.Append("Your Email Address</br> Your City, State Zip</br>Your Phone </br> Your Newsletter URL</br> </td></tr> </table>");
//now in the stringbuilder class sbody there will be complete html code afer execution of the code.
// now i am explainning that how we send the email as with newsletter
//pass four parameters inside the below line. See next line here am explainning about all the parameters
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage("write the complete email address of sender", "write the complete email address of receiever", "Info or here you can also write the heading of a mail", sbody.ToString());
// you can also attach somthing with this mail. below am writting a code of the attachment of a file
if (attach_file.HasFile)
{
mail.Attachments.Add(new Attachment(attach_file.PostedFile.InputStream, attach_file.FileName));
}
mail.CC.Add("bharti222000@yahoo.com");
// mail.CC.Add(" here u can write another email address as cc");
System.Net.NetworkCredential mailAuthenticaion = new System.Net.NetworkCredential("here write the email address of the sender", "here write the password of your email address");
// in the below line i am writting the smtp address of gmail and port number
System.Net.Mail.SmtpClient mailclient = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);
mailclient.EnableSsl = true;
mailclient.Credentials = mailAuthenticaion;
// in below line i am writting IsBodyHtml = true; because am sending html code with this mail.
mail.IsBodyHtml = true;
mailclient.Send(mail);
//Label1.Visible = True
lbl_msg.Text = ("your e-mail has been sent");
}
catch (Exception ex)
{
lbl_msg.Text = ex.Message;
}
finally
{
}
}
protected void send_Click(object sender, EventArgs e)
{
// here i am calling the function named snd_mail() at the click of the button
snd_mail();
}
}
