Send Email Using ASP.NET In GoDaddy Server

Nowadays, sending an email is a small kind of task. We can send email in ASP.NET using a Local Server easily. But on the GoDaddy Server, a little bit of code should be changed, like Port Number, Hosting Server, and user credentials etc.

Following are the steps.
 
Note - This code will work only on GoDaddy Server, not on a Local Server.
 
Step 1 Create a new project.

Step 2 Add bootstrap CSS in the CSS folder. 

Step 3 Create a webform aspx page. 

Step 4 Design the form like below.
  1. <!DOCTYPE html>  
  2. <html xmlns="http://www.w3.org/1999/xhtml">  
  3.   
  4. <head runat="server">  
  5.     <title></title>  
  6.     <link href="css/bootstrap.min.css" rel="stylesheet" />  
  7. </head>  
  8.   
  9. <body>  
  10.     <form id="form1" runat="server">  
  11.         <div class="container">  
  12.             <div class="row">  
  13.                 <div class="col-md-4 col-md-offset-4">  
  14.                     <div class="panel panel-primary">  
  15.                         <div class="panel-heading">  
  16.                             <h3 class="panel-title">E-mail</h3>  
  17.                         </div>  
  18.                         <div class="panel-body">  
  19.                             <label>Name</label>  
  20.                             <asp:TextBox ID="txtname" runat="server" CssClass="form-control" placeholder="Name"></asp:TextBox>  
  21.                             <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Please Provide Name" ControlToValidate="txtname" ForeColor="Red"></asp:RequiredFieldValidator><br />  
  22.                             <label>Subject</label>  
  23.                             <asp:TextBox ID="txtsubj" runat="server" CssClass="form-control" placeholder="Subject"></asp:TextBox>  
  24.                             <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Please Provide Subject" ControlToValidate="txtsubj" ForeColor="Red"></asp:RequiredFieldValidator><br />  
  25.                             <label>Mobile</label>  
  26.                             <asp:TextBox ID="txtmob" runat="server" CssClass="form-control" placeholder="Mobile Number" MaxLength="12"></asp:TextBox>  
  27.                             <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ErrorMessage="Please Provide Mobile Number" ControlToValidate="txtmob" ForeColor="Red"></asp:RequiredFieldValidator><br />  
  28.                             <label>Email</label>  
  29.                             <asp:TextBox ID="txtemail" runat="server" CssClass="form-control" placeholder="Email ex([email protected])"></asp:TextBox>  
  30.                             <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ErrorMessage="Please Provide Email-ID" ControlToValidate="txtemail" ForeColor="Red"></asp:RequiredFieldValidator><br />  
  31.                             <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="Please Proide Valid Email-ID" ControlToValidate="txtemail" ForeColor="Red" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator><br />  
  32.                             <label>Address</label>  
  33.                             <asp:TextBox ID="txtaddress" runat="server" CssClass="form-control" placeholder="Address"></asp:TextBox>  
  34.                             <asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ErrorMessage="Please Provide Address" ControlToValidate="txtaddress" ForeColor="Red"></asp:RequiredFieldValidator><br />  
  35.                             <asp:Button ID="Button1" runat="server" Text="Send Me" CssClass="btn btn-block btn-primary" OnClick="Button1_Click" />  
  36.                         </div>  
  37.                     </div>  
  38.                 </div>  
  39.             </div>  
  40.         </div>  
  41.     </form>  
  42. </body>  
  43.   
  44. </html>   
Step 5

Add Server-side validation for every field. Use RequiredFieldValidator for checking the empty fields.

Step 6

Each FieldValidator needs to set the ControlToValidate in the properties.

Step 7

The Email Validation requires another validator like RegularExpressionValidator to check a valid Email-ID. Using ValidationExpression, we can check easily.
 
Step 8

Double click on "Send Me" button and add the below code.
  1. try {  
  2.     MailMessage msgs = new MailMessage();  
  3.     msgs.To.Add(txtemail.Text.Trim());  
  4.     MailAddress address = new MailAddress("[email protected]");  
  5.     msgs.From = address;  
  6.     msgs.Subject = "Contact";  
  7.     string htmlBody = @ " <  
  8.         !DOCTYPE html >  
  9.         <  
  10.         html >  
  11.         <  
  12.         head >  
  13.         <  
  14.         title > Email < /title> <  
  15.         /head> <  
  16.         body >  
  17.         <  
  18.         h1 > Hi welcome < /h1> <  
  19.         p > Thank you  
  20.     for register < /p> <  
  21.         /body> <  
  22.         /html>  
  23.     ";  
  24.     msgs.Body = htmlBody;  
  25.     msgs.IsBodyHtml = true;  
  26.     SmtpClient client = new SmtpClient();  
  27.     client.Host = "relay-hosting.secureserver.net";  
  28.     client.Port = 25;  
  29.     client.UseDefaultCredentials = false;  
  30.     client.Credentials = new System.Net.NetworkCredential("[email protected]", "password");  
  31.     //Send the msgs  
  32.     client.Send(msgs);  
  33.     ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Your Details Sent Successfull.');", true);  
  34. } catch (Exception ex) {}  
Step 9

Run the application. You will get an error like the following.

WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive).

Step 10

So, add the below code in web.config.
  1. <appSettings>  
  2.     <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />  
  3. </appSettings>  
Step 11

Run the application again. Now, you will get a form like the following.

 
Step 12

Just click the "Send Me" button. You will get an error message like below.

 
Step 13

Fill in all the fields and provide a valid Email-ID.

 
The mail is sent successfully.
