How we work it out
Monthly records = agents × working days × records per agent per day. The right number per agent depends on your dialler, your connect rate and how long calls last: predictive dialler teams often get through a few hundred records per agent per day, manual dialling far fewer.
Tips to make the data go further
- Add an HLR check so your dialler doesn't waste attempts on dead numbers.
- Take a live feed rather than one big file, so agents always call the freshest records first.
- Upload a suppression file of existing customers so you don't pay for them again.
- Recycle no-answers at different times of day before moving on.
