Send email with Link in it in ASP.Net

Ref:Send email with attachment in ASP.Net using C# VB.Net

I have removed the attachment code in below html and VB code.

Check this code with Gmail account if you are able to receive it then there is a problem with omport.com or sbsales.net

HTML:

<form id="form1" runat="server">
    <div>
        <table border="0" cellpadding="0" cellspacing="0">
            <tr>
                <td style="width: 80px">
                    To:
                </td>
                <td>
                    <asp:TextBox ID="txtTo" runat="server"></asp:TextBox>
