Hello! You must get tired of hearing this, but I am very new to this. I am exploring macros in a range of Office applications to make life easier for my staff and myself.

Every few months, we need to send out emails to a mailing list of about 4000 people. Outlook's limitations mean that we need to break this list up into about 15 different emails, and we still run into problems.

Today, I managed to cobble together a macro that will call up Outlook from Excel and send an email from a list of addresses.

The problem is this - my company uses Titus Labs Message Classification system. At the moment, if I run the code, someone has to sit and manually add the classification to every single email. Not very practical for 4000 emails!

I am trying to work out a way to automatically add the required classification. I have checked in the references in the VB editor and found the reference to the library; I have looked in the program files on the system and found that it appears to be a DLL. I don't know what language it is written in.

Does anyone have experience with this particular add in, or have any general advice that I can try?

Thanks in advance for your tolerance and assistance.
