Using a custom export method with standard List&Label mail handling

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.
