Recruiting dialers

The main difference between them is how many lines open at once. A power dialer works a list one number at a time, dialing the next as soon as you hang up. A parallel dialer opens several lines simultaneously and connects you to whoever answers first — many more conversations per hour, at the cost of occasional dropped calls and a heavier compliance burden. Preview dialers sit in between, giving you a few seconds with the record before the call goes out.

Agency and high-volume staffing teams feel the difference first. If your recruiters are working down a list rather than returning scheduled calls, this is usually the highest-leverage tool they own.

Worth checking before you buy: how the vendor protects caller ID reputation, since carrier spam labeling now costs more connect rate than bad lists do; whether local presence is included and where the numbers come from; how deeply it writes back to your ATS, and whether call notes and recordings reach the candidate record automatically; per-seat versus per-minute pricing at your real volume; and how it handles consent, recording notification and do-not-call rules across the states you work in.
