Here is quick example, assuming col A = Email, Col B = Subject & Col C = Path
Option Explicit
Public Sub Example()
Dim olApp As Object
Dim olMail As Object
Dim olRecip As Object
Dim olAtmt As Object
Dim iRow As Long
Dim Recip As String
Dim Subject As String
Dim Atmt As String
iRow = 2
Set olApp = CreateObject("Outlook.Application")
Dim Sht As Worksheet
Set Sht = ThisWorkbook.Worksheets("Sheet1")
Do Until IsEmpty(Sht.Cells(iRow, 1))
Recip = Sht.Cells(iRow, 1).Value
Subject = Sht.Cells(iRow, 2).Value
Atmt = Sht.Cells(iRow, 3).Value ' Attachment Path
Set olMail = olApp.CreateItem(0)
With olMail
Set olRecip = .Recipients.Add(Recip)
.Subject = Subject
.Body = "Hi "
.Display
Set olAtmt = .Attachments.Add(Atmt)
olRecip.Resolve
End With
iRow = iRow + 1
Loop
Set olApp = Nothing
End Sub
