What is a auto dialer?

An auto dialer is any system that places outbound calls without a person keying digits. There are four modes — power, preview, progressive and predictive — and they differ in how many calls run per rep and who hears the phone ring first. All four are in the base product here, switchable per campaign.
Why auto dialer works better on numbers you own: on a shared pool your calls are a small fraction of the traffic from the same block, so the caller-ID reputation is mostly other businesses' calling and signing caps at B attestation. On owned numbers the reputation is your own, callbacks reach your team, and calls sign at A attestation with CNAM registered.
Auto dialer runs on numbers you own outright, which is what the diagram's right-hand column describes.

How it works

Auto dialer in four steps

No implementation project. Most teams are dialling the same day they sign up.

  1. 1

    Load the list and let it clean itself

    Import a CSV or pull a CRM segment. Numbers are validated, formatted to E.164, deduplicated, and screened against your suppression and do-not-call lists before anything dials.
  2. 2

    Choose the mode for the campaign

    Preview for high-value accounts, power for curated lists, predictive only where you have the agent pool to keep abandonment inside the legal limit. The mode is a campaign setting, not a purchase decision.
  3. 3

    Set the guardrails

    Calling window in the contact's own time zone, per-number daily dial caps, which owned numbers to present, and what happens on each disposition.
  4. 4

    Dial, disposition, and follow up

    Reps talk; the system logs the outcome, writes it back to the CRM, and triggers the next step — a task, a text, a sequence, or a suppression entry.

Capabilities

What you get

Four modes, one licence

Power, preview, progressive and predictive are all included. Switch per campaign, per list, or per hour of the day rather than buying a different product.

Abandonment controls that are on by default

Predictive pacing is bounded by the abandonment limit rather than by an optimistic pacing target, and the required recorded message plays on any call that goes unattended.

Numbers you own

Caller ID reputation attaches to the number. Dialing from numbers you own means the reputation is your own calling, and calls sign at Attestation A rather than capping at B.

Answering-machine detection

Voicemail is detected and handled — dropped, or given a pre-recorded message — without a rep waiting through a greeting.

Compliance guardrails, not add-ons

Calling hours by the contact's time zone, DNC suppression, consent records, and per-number caps ship with the product rather than as a paid module.

Usage pricing

No seat licences. You pay for connected minutes and number rentals, which is what makes running four modes on one platform economic in the first place.

Which dialing mode should you actually run?

Mode is the only decision here that changes outcomes, and it is decided by two numbers: how many reps are dialing at once, and what share of your list answers. Everything else is preference.

The mode is a campaign setting here, not a product tier.
ModeLines per repWho it suitsMain risk
Preview1, dialed on the rep's signalHigh-value accounts where research before the call changes the conversationSlowest by design; reps spend time reading
Power1, dialed automaticallyCurated lists and follow-up cadences — the sensible defaultNone to speak of, which is why it is the default
Progressive1, paced to agent availabilityInbound-outbound blended teamsPacing that drifts when agent availability is volatile
PredictiveSeveral, paced by an algorithmLarge agent pools on cold lists with known answer ratesAbandoned calls, which are capped by rule and by statute

The abandonment rule that decides whether predictive is available to you

Predictive dialing places more calls than there are free agents, on the assumption most will not be answered. When that assumption is wrong, somebody answers a call with no agent to take it — an abandoned call. The Telemarketing Sales Rule caps abandoned calls at 3% of answered calls, measured over a 30-day period per campaign, requires the call to connect within two seconds of the greeting finishing, and requires a recorded identification message on any call that is abandoned.

The practical consequence: predictive dialing is only workable with an agent pool large enough that the pacing algorithm has room to be wrong. Below roughly ten concurrent agents, the maths does not hold and you are running a compliance risk to save minutes you were not going to lose anyway.

The limit is on abandoned calls, not on dial volume

It is measured as a share of answered calls, so a campaign with a low answer rate reaches the cap faster than the raw dial count suggests. Track it per campaign, not per account.

What actually changes your connect rate

Teams buy dialers expecting more conversations and measure more dials. Those are different things, and the gap between them is where the money goes. The arithmetic is worked through in connect rate vs contact rate, but the short version is that dialing faster multiplies whatever your answer rate already is — so a list answering at 4% dialed twice as fast produces twice as little of nothing.

  • Number reputation decides whether the phone shows your name or the word Spam. It is the largest single lever and it has nothing to do with the dialer.
  • Local presence lifts answer rates where the callee recognises the area code — provided the number is one you own rather than a pool number a stranger has already burned.
  • Time of day, in the contact's time zone, moves answer rates more than any pacing setting.
  • List quality. Validated, deduplicated, freshly sourced numbers answer; scraped lists do not, at any dialing speed.

Fit

Who a auto dialer is right for

If none of these describe you, a different mode probably fits better; the comparison pages lay out the trade-offs honestly.

  • Teams running more than about 40 outbound calls per rep per day
  • Anyone whose reps currently copy numbers out of a CRM by hand
  • Operations that need different pacing for different lists in the same week
  • Regulated sellers who need the compliance controls demonstrable, not assumed

Frequently asked questions

Is an auto dialer legal?
Yes, with conditions that depend on who you are calling and what you are calling about. Consent requirements, do-not-call scrubbing, permitted calling hours and abandonment limits all apply, and they attach to you as the caller rather than to the software. The obligations are covered in our TCPA guide.
What is the difference between an auto dialer and a power dialer?
Auto dialer is the umbrella term for any system that dials without a person pressing digits. A power dialer is one mode within it — exactly one call per rep at a time. Predictive and parallel dialing are also auto dialing; they simply run more lines.
How much does an auto dialer cost?
Here, there is no dialer licence: you pay for connected minutes and the numbers you rent, both published on the pricing page. Platforms that charge per seat typically land between $100 and $150 per rep per month before usage, which is why the crossover maths matters more than the sticker price.
Will an auto dialer get my numbers marked as spam?
The dialing method is not what triggers a spam label. High volume from one number, very short average call duration, low answer rates and complaints are. Owned numbers, branded caller ID, sensible daily caps per number and reputation monitoring are what keep calls clean.
Which mode should I start with?
Power dialing, in almost every case. It removes the dead time without introducing abandonment risk, and it tells you what your list's real answer rate is — which is the number you need before deciding whether parallel or predictive is worth the complexity.
