Autoresponder integration

[JohnGBSA]

I'm trying to find out if there are any mods/hacks to integrate an autoresponder and newsletter mailing program into vBulletin.

Right now I am using Sendstudio (from www.interspire.com) but I can find absolutely nothing on the integration of this or any other program.

Any help or suggestions would be greatly apreciated.

Thanks,

John
