Callbox has done an excellent job for us, we have closed their leads and have several more in the pipeline. Many of these new leads were some we did not have in our database. So their list is worthwhile too.

Expect the first month be used to fine tune the call list. We had trouble with this. We were somewhat inexperienced choosing the correct SIC codes. I also listened to someone else and lowered the minimum revenue number; disaster. They are effective so make sure they are calling the people in your wheelhouse or you will be smothered with leads you don’t want. We gave them a script to capture information important to us so we could determine easily the value of the lead.

I have worked with Callbox since Jan 2009. I find them professional, helpful, and reliable. They do a great job of getting our prospects to sign up for a webinar or a face to face meeting. I would recommend them to anyone who needs telemarketing services!
