If you can live with requiring CDO to be present on the machine, and you don't mind a user-provided SMTP server, you can use that. Just google for some example code, but for you convenience I'll paste some below from www.rondebruin.nl :
Sub CDO_Mail_Small_Text()
Dim iMsg As Object
Dim iConf As Object
Dim strbody As String
' Dim Flds As Variant
Set iMsg = CreateObject("CDO.Message")
Set iConf = CreateObject("CDO.Configuration")
' iConf.Load -1 ' CDO Source Defaults
' Set Flds = iConf.Fields
' With Flds
' .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
' .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") _
' = "Fill in your SMTP server here"
' .Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
' .Update
' End With
strbody = "Hi there" & vbNewLine & vbNewLine & _
"This is line 1" & vbNewLine & _
"This is line 2" & vbNewLine & _
"This is line 3" & vbNewLine & _
"This is line 4"
With iMsg
Set .Configuration = iConf
.To = "[email protected]"
.CC = ""
.BCC = ""
.From = """Ron"" <[email protected]>"
.Subject = "Important message"
.TextBody = strbody
.Send
End With
End Sub
Adding an attachment would be done using .AddAttachment "C:\files\filename.pdf" on the iMsg.
