You may want look at the MailJob
class (when using .NET) or the LsMailSendFile
API when using the API - both approaches allow to send emails directly.
Also, you may set the Export.Mail.AttachmentList
export option via LL.ExportOptions.Add
or LlXSetParameter
(see chapter 7.5.2 in the programmer’s reference) to add files to the email created by the export process.
