2026 DIALER MODE GUIDE · Last Updated July 22, 2026
A predictive dialer completes roughly 150 to 300 calls per rep per hour by dialing ahead of agent availability, a power dialer runs 80 to 120 calls per hour on a strict one-to-one pacing ratio, and a preview dialer trades volume for context, letting an agent review a contact before every call, according to JustCall's 2026 dialer comparison. The right mode depends on team size and abandonment risk under the Telephone Consumer Protection Act, not just raw call volume.
All three modes automate outbound dialing, but they differ in how far ahead of agent availability they dial and how much context an agent sees before the call connects.
Figures below reflect commonly cited industry ranges for each dialer mode, sourced from a 2026 dialer comparison.
| Dialer Mode | Calls per Rep per Hour | Abandoned Calls | Minimum Team Size |
|---|---|---|---|
| Power dialer | 80–120 | None | 1+ |
| Progressive dialer | 100–150 | None | 3+ |
| Predictive dialer | 150–300 | Present, must stay under 3% (TCPA) | 8+ |
Figures per JustCall's 2026 power dialer vs. predictive dialer comparison. Actual results vary by list quality, industry, and agent staffing, so treat these as planning ranges rather than guarantees.

Team size and lead type, more than company size alone, decide which mode fits.
A power dialer fits best: small headcount, relationship-driven cold outreach, no abandonment risk.
A predictive dialer fits: enough agents to keep abandonment under 3% while maximizing live conversations.
A progressive dialer fits: more throughput than power mode without predictive's compliance overhead at this headcount.
Predictive dialing's speed advantage comes with an abandonment-rate ceiling under the Telephone Consumer Protection Act, and running it below roughly 8 agents makes that ceiling hard to hold in practice.

MightyCall's Power plan includes a progressive dialer, a lower-risk starting point before a team is ready for predictive-mode volume.
A power dialer places one call per agent at a time, the moment that agent is free, with no abandoned calls. A predictive dialer dials multiple numbers ahead of agent availability to maximize volume, which introduces abandonment risk that power dialing avoids.
Most guidance puts the minimum around 8 agents, since smaller teams cannot reliably keep the abandonment rate under the 3% ceiling TCPA compliance requires.
They're closely related but not identical. Progressive dialing runs one or a few lines per agent only when that agent is free, typically reaching 100 to 150 calls per hour versus a power dialer's 80 to 120, with zero abandoned calls in both modes.
Preview or power dialing is the standard choice, since an agent reviews or is instantly available for every contact, which keeps abandonment risk at zero for regulated outbound communications.
Yes. Most cloud dialer platforms let a team start on power or progressive mode and move to predictive once headcount and list quality support it, without a full platform migration.
Compare Core, Pro, and Power plans, and see where the progressive dialer fits your team size.
