Sending e-mails with ASP.NET is pretty straight forward. The .NET
framework comes with an entire namespace for handling e-mails, the
System.Net.Mail namespace
HTML Markup
The HTML Markup has a form with some
fields such as Recipient Email address, Subject, Body, Attachment,
Gmail account email address, Gmail account password and a Button to send
the email.
<body>
<form id="form1" runat="server">
<div align="center">
<h3>Send Mail To Your's Gmail Using ASp.net</h3>
<table>
<tr>
<td>Gmail User</td>
<td>:</td>
<td>
<asp:TextBox ID="txtfrom"
runat="server"
></asp:TextBox>
</td>
</tr>
<tr>
<td>Gmail Password</td>
<td>:</td>
<td>
<asp:TextBox ID="txtpassword"
TextMode="Password"
runat="server"
></asp:TextBox>
</td>
</tr>
<tr>
<td>Subject</td>

<td>
<asp:TextBox ID="txtsub" runat="server"
></asp:TextBox>
</td>
</tr>
<tr>

</td>
</tr>
