I would advise against this for a few reasons...and without knowing more, some of them won't apply.
It would help if you would expand on:
- what are you trying to accomplish (a call back from them, a warm transfer to a live operator, someone to visit your site etc)
- where did you get the list to be called
- are you trying to reach consumers or businesses
- how many numbers are on this list, how old is it etc
I would advise against it because:
- if these people haven't expressed interest, you are just spamming/annoying them and you are not going after a targeted market, which is a waste of time and money
- if you want to reach people business or consumer, why don't you call, or hire someone to call this list and TALK to people to determine actual qualified, interested parties
- if it's a residential list, have you run it through the DNC
- it is not the best way to generate revenue or new business as it is just throwing out a huge net not knowing what's under it
I'd be happy to help if you want some other options.
