Solution 1

you're using the wrong variant of SmtpClient.Send

clue: where's it going, what's the subject?

Solution 2

This is because you passing just a string to the SmptpClient.Send() method.
This method has two forms i.e, it has one overload. The first form takes 1 parameter of type MailMessgae and this is what you have used in your code. You need to have following information
1. from (email id),
2. to (email id),
3. subject &
4. body
But in your code you have only body .

Instead of -

VB

client.Send(body)

Try this-

VB

client.Send(fromaddress@yourdomain.com,toaddress@yourdomain.com,"Your Subject",body)

Hope, it helps :)

Private Sub SendHtmlFormattedEmail(ByVal recepientEmail As String, ByVal subject As String, ByVal body As String)
'After config mailSettings section in web.config, you don't need to initialization client's property
Dim client As New SmtpClient()
Dim message As New MailMessage()
message.Body = body
message.To.Add(recepientEmail)
message.Subject = subject
message.IsBodyHtml = True
client.Send(message)
End Sub
