Macro to remove duplicates and send email?

Hi Guys

I work for an online retail store and have a spreadsheet that I use to order stock in from other stores and suppliers. I bastardised a macro I found online to email a selection of cells.

These are the steps that the macro does:
Copy the range and create a new workbook to past the data in
Publish the sheet to a htm file
Read all data from the htm file into RangetoHTML
Close TempWB
Delete the htm file we used in this function

I also need it to remove duplicates before it sends the email but I'm not quite sure how to do this, can anyone help me?

I might have just solved it myself. Can someone please let me know if you see any problems with this? It seems to work for now...

I just added it in to Function RangetoHTML(rng As Range) after the section 'Copy the range and create a new workbook to past the data in

    'Removes Duplicates
    Dim x               As Long
    Dim LastRow         As Long
     
    LastRow = Range("A65536").End(xlUp).Row
    For x = LastRow To 1 Step -1
        If Application.WorksheetFunction.CountIf(Range("A1:A" & x), Range("A" & x).Text) > 1 Then
            Range("A" & x).EntireRow.Delete
