This Outlook VBA will load an excel file with emails stored as records and send all of them.

Option Explicit

 Private Const xlUp As Long = -4162

Sub SendEmailsFromExcel()

    Dim xlApp As Object

    Dim isEmailTo As String    ' Col A
    Dim isSubject As String    ' Col B
    Dim isMessage As String    ' Col C

    Dim i As Integer
    Dim objMsg As MailItem
    Set objMsg = Application.CreateItem(olMailItem)

    Dim emailsMatrix As Variant

    Dim objWB As Object
    Dim objWs As Object
    Dim FileStr As String

    FileStr = "C:\Users\...\Documents\EmailsInExcel.xlsx"

    Set xlApp = CreateObject("excel.application")

    With xlApp
        .EnableEvents = False
        .DisplayAlerts = False
    End With

    Set objWB = xlApp.Workbooks.Open(FileStr)
    Set objWs = objWB.Sheets(1)

    ' Matrix load:  A - Email Address, B - Subject, C - Body
    emailsMatrix = objWs.Range("A1:C" & xlApp.Cells(objWs.Rows.Count, "A").End(xlUp).Row)

    objWB.Close

    Set objWB = Nothing
    xlApp.Quit
    Set xlApp = Nothing

'   Done getting Excel emails file.

    For i = 1 To UBound(emailsMatrix)
        isEmailTo = emailsMatrix(i, 1)
        isSubject = emailsMatrix(i, 2)
        isMessage = emailsMatrix(i, 3)


        objMsg.Recipients.Add isEmailTo
        objMsg.Subject = isSubject
        objMsg.Body = isMessage
        objMsg.Send
    Next i

End Sub
