Excel VBA macro to send emails to unique users in range

I'm trying to create a VBA macro that will look into the A column, find all unique email addresses, create a new outlook email for each and populate the body of that email with the rows where that email is present (also including the header).

Example data:

+----------------+---------------------+---------+
|     Email      |     Application     | Version |
+----------------+---------------------+---------+
| test1@test.com | Microsoft_Office_13 | v2.0    |
| test1@test.com | Putty               | v3.0    |
| test1@test.com | Notepad             | v5.6    |
| test2@test.com | Microsoft_Office_13 | v2.0    |

| test2@test.com | Putty               | v3.0    |
| test2@test.com | Adobe_Reader        | v6.4    |
| test3@test.com | Microsoft_Office_13 | v3.6    |
| test3@test.com | Paint               | v6.4    |
| test3@test.com | Adobe_Reader        | v6.4    |
+----------------+---------------------+---------+

This is what I was able to find in my research, but it will create an email for every time the address is listed. It also doesn't really have any code which shows how to pull a range of cells into the body.

Sub Test1()
    Dim OutApp As Object
    Dim OutMail As Object
    Dim cell As Range

    Application.ScreenUpdating = False
    Set OutApp = CreateObject("Outlook.Application")

    On Error GoTo cleanup

    For Each cell In Columns("A").Cells.SpecialCells(xlCellTypeConstants)
        If cell.Value Like "?*@?*.?*" And _
           LCase(Cells(cell.Row, "C").Value) = "yes" Then

            Set OutMail = OutApp.CreateItem(0)
            On Error Resume Next
            With OutMail
                .To = cell.Value
                .Subject = "Reminder"
                .Body = "Hi, please find your account permissions below:"

                .Display
            End With
            On Error GoTo 0
            Set OutMail = Nothing
        End If
    Next cell

cleanup:
    Set OutApp = Nothing
    Application.ScreenUpdating = True

End Sub

The desired email output would be something like:

Hi, please find your account permissions below:

+----------------+---------------------+---------+
|     Email      |     Application     | Version |
+----------------+---------------------+---------+

| test2@test.com | Microsoft_Office_13 | v2.0    |
| test2@test.com | Putty               | v3.0    |
| test2@test.com | Adobe_Reader        | v6.4    |
+----------------+---------------------+---------+

Answer

I used the code from my answer mentioned in the comment and modified it.
Create a class and name it AppInfo. Here you find how to do that

Option Explicit


Public app As String
Public version As String

Then put the following code into a module. The asumption is that the data is in the active sheet starting in A1 with the header Email, Application and Version.

Option Explicit

Sub Consolidate()


#If Early Then
    Dim emailInformation As New Scripting.Dictionary
#Else
    Dim emailInformation As Object
    Set emailInformation = CreateObject("Scripting.Dictionary")
#End If

    GetEmailInformation emailInformation
    SendInfoEmail emailInformation

End Sub


Sub GetEmailInformation(emailInformation As Object)

Dim rg As Range
Dim sngRow As Range

Dim emailAddress As String
Dim myAppInfo As AppInfo

Dim AppInfos As Collection

Set rg = Range("A1").CurrentRegion    ' Assuming the list starts in A1 and DOES NOT contain empty row
Set rg = rg.Offset(1).Resize(rg.Rows.Count - 1)    ' Cut the headings

    For Each sngRow In rg.Rows

        emailAddress = sngRow.Cells(1, 1)

        Set myAppInfo = New AppInfo

        With myAppInfo
            .app = sngRow.Cells(1, 2)
            .version = sngRow.Cells(1, 3)
        End With

        If emailInformation.Exists(emailAddress) Then
            emailInformation.item(emailAddress).Add myAppInfo
        Else
            Set AppInfos = New Collection
            AppInfos.Add myAppInfo

            emailInformation.Add emailAddress, AppInfos
        End If

    Next

End Sub
Sub SendInfoEmail(emailInformation As Object)

Dim sBody As String
Dim sBodyStart As String

Dim sBodyInfo As String
Dim sBodyEnd As String
Dim emailAdress As Variant
Dim colLines As Collection
Dim line As Variant

    sBodyStart = "Hi, please find your account permissions below:" & vbCrLf


    For Each emailAdress In emailInformation

        Set colLines = emailInformation(emailAdress)
        sBodyInfo = ""
        For Each line In colLines
            sBodyInfo = sBodyInfo & _
                         "Application: " & line.app & vbTab & "Version:" & line.version & vbCrLf
        Next
        sBodyEnd = "Best Regards" & vbCrLf & _
                   "Team"

        sBody = sBodyStart & sBodyInfo & sBodyEnd

        SendEmail emailAdress, "Permissions", sBody
    Next


End Sub

Sub SendEmail(ByVal sTo As String _
              , ByVal sSubject As String _
                , ByVal sBody As String _
                  , Optional ByRef coll As Collection)



    #If Early Then
        Dim ol As Outlook.Application
        Dim outMail As Outlook.MailItem
        Set ol = New Outlook.Application
    #Else
        Dim ol As Object
        Dim outMail As Object
        Set ol = CreateObject("Outlook.Application")

    #End If

    Set outMail = ol.CreateItem(0)

    With outMail
        .To = sTo
        .Subject = sSubject
        .Body = sBody
        If Not (coll Is Nothing) Then
            Dim item As Variant

            For Each item In coll
                .Attachments.Add item
            Next
        End If

        .Display
        '.Send
    End With

    Set outMail = Nothing


End Sub
