# Bulk calling campaigns: how to call a lead list with AI

> A bulk calling campaign uploads a lead list and has an AI voice agent call every number, qualify interest, and book a next step, with automatic retries for no-answers. It is the fastest way to revive an old lead database, because the agent calls the whole list at once instead of one at a time.

## When bulk calling is the right tool

- Reviving an old enquiry list for a new launch or batch
- End-of-month or festive offer pushes
- Re-engaging dormant customers

## How to run one well

1. Clean the list and keep only consenting contacts
2. Set the agent's job: qualify and book, or just confirm interest
3. Let it call the list with retries on no-answer
4. Review outcomes and hand hot leads to a human

## Prepare the list

Remove duplicates and numbers that are not 10-digit Indian mobiles, keep each lead's name and what they enquired about, and drop anyone who asked not to be called. A clean list with context lets the agent open with 'You asked about the 2BHK in Kokapet' instead of a generic pitch, which is what earns the next minute of the call.

## Read the results

- Connected rate: how many numbers answered, after retries
- Interested rate: connected calls that ended in a yes or a callback
- Booked next steps: visits, appointments or counselling sessions on the calendar
- Cost per booked next step: talk-time spent divided by bookings

> Keep campaigns consent-aware and within [TRAI and DLT rules](https://agents.elevatebox.in/guides/ai-calling-rules-india-trai-dlt).

## Frequently asked questions

### Can I call an old lead list with AI?

Yes, if the contacts consented. Bulk calling an old list is one of the highest-return uses of an AI caller.

### How many times should the agent retry a number?

Two or three attempts spread across different times of day reach most people who will answer at all. More than that rarely adds connections and starts to annoy.

### What does a bulk calling campaign cost?

With per-second billing you pay only for connected talk-time: ₹7.98 a minute at ElevateBox, and unanswered calls cost nothing. Estimate your list with the [AI calling cost calculator](https://agents.elevatebox.in/tools/ai-calling-cost-calculator).
