Excel form - outlook document

I have a form that I've created in excel which then populates a word document, I've been asked whether I can have the same form populate an outlook document. I currently have the following script to open the word doc - what would I need to do in order to create an email instead of the word doc?

Private Sub CommandButton1_Click()
Dim wapp As Word.Application
Dim wdoc As Word.Document
If Me.OptionButton1 = True Then
Set wapp = CreateObject("Word.Application")
Set wdoc = wapp.Documents.Open("\\emea\emeadata\Alesco\Financial Risks\Key Information Pack\Gallagher\AJG Advised - Wholesale.dotx")
wapp.Visible = True
ElseIf Me.OptionButton2 = True Then
Set wapp = CreateObject("Word.Application")
Set wdoc = wapp.Documents.Open("\\emea\emeadata\Alesco\Financial Risks\Key Information Pack\Gallagher\AJG Advised - Retail New.dotx")
wapp.Visible = True
End If
