Sending Email in ASP.NET Using Gmail Account

In this article, I tried to explain a common requirement which implemented more frequently in various ways.

• Sending confirmation email after registration
• Sending email for Password Reset
• Notification mails

Like this we can implement these requirements in many ways, In these scenarios, we get some error occur like SMTP Server related. In my previous article, I already discussed this issue and showed the solution and resolved the SMTP Server issue. I strongly recommend reading that SMTP Server Secure Connection and Authentication Error article before continuing this current tutorial.

HTML Markup: Create Sending Email Page

In the *.aspx page design the user interface according to the requirements shown in the above image. Create a web page with HTML markup to input the email address, compose the email message body, and add a sending button which executes the sending mail process.

 <div>
     <table>
      <tr>
      <td>
       <table>
      <tr>
       <th colspan="2" align="left">Single Mail Sending</th>
      </tr>
      <tr>
      <td style="width:20px;">To : </td><td><asp:TextBox ID="txt_single_mail" runat="server" Width="310px"></asp:TextBox></td>
      </tr>
      <tr>
      <td colspan="2">
       <asp:TextBox ID="txt_single_msg" runat="server" TextMode="MultiLine" Width="336px" 
              Height="199px"></asp:TextBox>
      </td>
      </tr>
      <tr>
       <td colspan="2">
        <asp:Button ID="Btn_single_mail" runat="server" Text="Send Single Mail" 
               onclick="Btn_single_mail_Click" />
       </td>
      </tr>
     </table>
      </td>
      </tr>
      </table>
      </div>

C# Coding: Sending Email

Next, implement the C# code to handle the button click event and send a single email using Gmail's SMTP server.

protected void Btn_single_mail_Click(object sender, EventArgs e)
    {
        MailMessage ms = new MailMessage("your Gmail ID", txt_single_mail.Text);
        ms.Subject = "Testing Sending Single Mail";
        ms.Body = txt_single_msg.Text;
        ms.IsBodyHtml = true;
        SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
        smtp.Credentials = new System.Net.NetworkCredential("your Gmail ID", "your Gmail ID Password");
        smtp.EnableSsl = true;
        smtp.Send(ms);
    }
