When receiving unsoliciting phone calls by telemarketers, many people consistently hung up, don't bait, and don't interact. So why don't telemarketers delete from their databases such phone numbers that don't lead to any sales or other business benefits?
Maybe the cost of keeping the numbers is so low telemarketers just don't bother. Or keeping track of what numbers to delete may actually have a cost. Or perhaps telemarketers hope those people will eventually pick up the calls.
Any insight?
Okay. But if a robocaller doesn't lead to results, it may be programmed to give up on unpromising numbers.
Sure it can be, what I'm trying to say is that there is no financial incentive for it to be though. Programming takes time and money, and there is literally no profit to be had for doing it.
