I don't have an answer to your question, but I will add my 2 cents in anyway!
I primarily use the DX Summit web site at http://oh2aq.kolumbus.com/dxs/
You can get spots for either HF or VHF. Furthermore, you can just ask for phone or CW spots. You can also get spots by band, but it doesn't break them down by mode. You can also get spots for Beacon, Digital, IOTA, QRP, Satellite and Mobile. These spots are in real time and are updated every few minutes.
Whith all due respect, it seems that getting spots by email is rather inefficient. It would seem that by the time you are sent the spot and it makes it's way into your system and assuming you get it in a timely manner, the DX could be gone. Since you need to be at your computer anyway to receive your email, why not just go to an online site and get them that way?
