How an auto dialer works and when it is worth using

The problem an auto dialer solves

Without a dialer, agents type every number, wait for it to ring and often reach a call nobody answers, a busy line or voicemail. Then they write down the result by hand and start again. A good part of the day is lost between one conversation and the next.

An auto dialer takes over this repetitive work. The system places the calls, detects who answered and only then hands the call to an agent, who already sees the contact's details on screen. The team spends less time dialing and waiting, and more time talking.

How an auto dialer works, step by step

1. The list is imported. Contacts come in from a spreadsheet, with one or more phone numbers per person. A good system checks the numbers and flags duplicates before saving.
2. The campaign is set up. You define calling hours, the number shown to the customer, the possible results (sale, not interested, call back later) and the fields the agent sees.
3. The system dials. Calls go out at the pace of the chosen dialing mode, without exceeding the operation's limit of simultaneous calls.
4. The answered call reaches the agent. Along with it come the name, the history and the campaign fields.
5. The result is recorded. The agent classifies the call and the next one arrives. Unanswered contacts go back to the queue after the interval you set.

The four dialing modes

What sets one dialer apart from another is mainly the pace: how many calls the system places for each free agent. Each mode suits a different kind of list and team.

If in doubt, start with Progressive. It is the safest mode, because it never calls someone without an agent available. Once the team is used to it and you know your list's answer rate, try Power or Predictive.

What happens to people who do not answer

In any list, some people will not answer on the first attempt. The dialer handles this on its own: busy, unanswered or voicemail calls go back to the queue after the interval you define. If the contact has more than one phone number, the system alternates between them on new attempts.

This avoids two common mistakes of manual operations: forgetting to try again and insisting too much on the same number in a short time.

When an auto dialer is worth it

• Telesales: offers, renewals and customer reactivation, with more contacts per hour.
• Collections: organized lists of pending payments and scheduled callbacks.
• Customer relations: after-sales, welcome calls and surveys conducted by agents.
• Outbound service: callbacks, confirmations and notices that need a person on the other end.

If the conversation does not need an agent, another tool is usually better. For a recorded notice or reminder, use outbound IVR or voice broadcasting. To collect scores and opinions, use phone surveys.

Precautions before you start

• List quality: outdated numbers bring down the answer rate. Clean the list and remove duplicates before importing.
• Calling hours: call when your audience usually answers and respect the hours allowed for your type of business.
• Rules and consent: follow the data protection and telemarketing rules that apply to you (in Brazil, the LGPD and Anatel's rules for sales calls) and honor requests from people who no longer want to be called.
• Monitoring: watch the answer rate, average talk time and team occupancy in the first days, and adjust the dialing mode if needed.
