Mass Send Different Emails to the same list at the same time?

[emmadesigns]

I was hoping someone could help. We need to send out over two thousand emails from a mailing list. However each email has a different code in the content. I have been asked to find out how to do this without sending it over two thousand times individually. Is there any software out there that will allow you to mass send out different emails to different email addresses from the same list and at the same time?

If you used something like Mailchimp you could import your mailing list and have a field for the individual code, so your mailing list file would be made up of first name, last name, email address and code. Then you would just call that field in the email which would be something like **CODE**. That's the only way I can think of doing it but it's still going to involve typing 2000 codes in!

Maybe someone more useful will be along soon...
