need to embed the url inside hyperlink in mail

Question

I have a button on an ASP.NET webpage. When the button is clicked an email is sent to users. Inside the body of the mail message I have the following URL; https://synerg.abc.com/abctool/Login.aspx.

Instead of having the full link visible, I just want to show a "Click Here" hyperlink which will take the user to the above URL when clicked. The URL should then be redirected to https://synerg.abc.com/documenttrackingtool/Login.aspx

protected void Uab_abc_Click(object sender, EventArgs e)
{
    SmtpClient smtpClnt;
    MailMessage objMail;

    // Prepare Email  
    // Load Email Template from HTML File. 

    // Send Email
    // Create new Mail Object
    objMail = new MailMessage(); // Create new Mail Object
    objMail.From = new MailAddress("tracking@abc.com");

    //test mailers
    objMail.To.Add(new MailAddress("abc@gmail.com"));
    objMail.CC.Add(new MailAddress("abc@gmail.com"));
    objMail.Bcc.Add(new MailAddress("abc@gmail.com"));

    objMail.Subject = "abc Delivery HNC";
    string EMailBody = @"  
        <table>  
            <tr>  
                <td>Dear L2 / L3 Heads,

Answer 1

You should change this:

<tr>  
    <td>Link : https://synerg.abc.com/tool/Login.aspx
    </td> 
</tr>

To this:

<tr>  
    <td><a href="https://synerg.abc.com/tool/Login.aspx">click here</a>
    </td> 
</tr>

And this:

<tr>  
    <td>Recovery Status Date : 13th November 2019
    </td>  
</tr>  

To this:

<tr>  
    <td>Recovery Status Date : #dateToReplace
    </td>  
</tr>  

Also:

EMailBody = EMailBody.Replace("#dateToReplace", DateTime.Now.ToString("d MMMM yyyy"));

// Now we'll create two email views: HTML and plain text
// First, create HTML view
AlternateView HTMLEmail = AlternateView.CreateAlternateViewFromString(EMailBody,
        null, "text/html");

Answer 2

Replace

<td>Link : https://synerg.abc.com/tool/Login.aspx</td> 

with

<td>Link : <a href='https://synerg.abc.com/tool/Login.aspx'>Login</a></td> 

Replace Login with the text you want to display, e.g., click here

---

Edit: Also Replace

<td>Recovery Status Date : 13th November 2019</td> 

with

<td>Recovery Status Date : [RECOVERYDATE]</td> 

Also include

EMailBody = EMailBody.Replace("[RECOVERYDATE]", DateTime.Now.ToString("d MMMM yyyy"));
