Is an Auto Dialer Right for Your Business?

Auto dialers are suitable for businesses with relatively low and predictable call volumes. It provides basic functionalities like automatic dialing and connecting calls to the agents at a minimal price. It can effectively support simple outbound campaigns, schedule appointments, automate follow-up calls, and send reminders. This dialer type supports surveys and data collection as it can quickly reach a large audience. Hence, businesses with few agents and small campaigns performing tasks like telemarketing, customer service surveys, or appointment reminders must opt for auto dialers.

Understanding Predictive Dialers and their Features

The predictive dialer is a narrower concept compared to an auto dialer. It is a type of auto-dialing that works within a specific framework. It anticipates the availability of agents and automatically connects them to the live calls. Moreover, it can predict the call answer rate and manage the dialing rate accordingly. Predictive dialers help an organization minimize idle time and maximize productivity by eliminating unanswered calls, busy signals, and voicemails. The essential features of this modern technology, driven by advanced algorithms, are as follows:

  • Adaptive Dialing: It automatically adjusts the dialing rate based on factors such as agent availability and call answer rates. By predicting real-time conditions, adaptive dialing ensures maximum agent productivity and reduced idle time.
  • Abandonment Rate Management: The percentage of calls the caller hangs up before connecting to the agent is called the abandonment rate. This management feature of the predictive dialer is used to monitor and control the rate of abandoned calls.
  • Do-Not-Call Compliance: It filters out numbers on the DNC list and prevents calling people who have registered their phone numbers on the Do-Not-Call Registry. SquadStack rigorously monitors for de-duplication and DND numbers to avoid spamming anyone.

Our lead matching engine ensures that only the agents with appropriate skills are assigned to specific tasks and calls, maximizing the chances of success.
  • Call Back Scheduling: Call back scheduling allows the agent to offer a call back at the customer’s preferred time. The predictive dialer schedules the call back for the agent and sends automated reminders to both the agent and the customer. It automatically connects the agents with the customers at the scheduled time.
