Status: written for testing, unexecuted, and not a customer result. Every name, order and answer here is made up. Adapt the wording to your business, and have your team approve it before any real call.
Details passed in before the call
Customer first name, brand, order number, item, attempt count, courier's reason code, next possible delivery date, and calling window.
What the agent may do
- Ask what happened, and record the answer.
- Record a preferred day, a time window, a landmark, or an alternate receiver.
- Ask whether the customer still wants the parcel.
- Promise only that the request has been passed on.
What it must not do
- Ask for, accept, or repeat an OTP, a card number, or UPI details.
- Change an address, cancel an order, or issue a refund.
- Promise a delivery time that your system hasn't confirmed.
- Tell the customer they were at fault.
The call
Agent: Hello, is this Asha? I'm an AI assistant calling for Example Store about your order of a blue kettle. Our courier couldn't deliver it yesterday. Do you have a minute?
Caller: Yes, but nobody came to my house.
Agent: I'm sorry about that. I'll note that no one reached you. Would you still like the parcel?
Caller: Yes, I need it.
Agent: Thanks. The next possible delivery day is Thursday. Would morning or afternoon suit you better?
Caller: Afternoon. And the courier should call me when they're near the temple. They never find the lane.
Agent: Got it. Thursday afternoon, and I've noted the temple as your landmark. Our delivery team will review this. I can't confirm an exact time, and they'll update you by message. Is there anything else to add?
Caller: No, that's all.
Agent: Thank you, Asha. Please remember that we'll never ask you for an OTP on this call. Goodbye.
When the conversation goes differently
Caller gives an OTP: "Please don't share that with anyone, including me. I haven't saved it." The agent shouldn't repeat it. Your team should also check that transcripts are handled accordingly, because the transcript may contain it.
Caller wants a new address: "I can't change the address on this call, but I'll flag your request for our team to verify."
Caller wants a person: "I can't connect you right now. I've noted this for our team, and they call back during working hours."
Caller says stop calling: "I understand. I'll note that request." Make sure that it reaches your do-not-call list.
The save fails: "I'm sorry, I couldn't save that just now. Please contact our support team." The agent mustn't say the request was passed on.
After the call
Send these fields to your delivery system by post-call webhook: reason_category, still_wants_parcel, preferred_day, preferred_window, landmark, alternate_receiver, needs_staff.
See the logistics workflow and the failed delivery guide.
Before your first real batch
Status: a blank planning sheet, unexecuted, and not a record of any customer result. Tick items only after you have checked them yourself.
Scope
- Choose which exception codes trigger a call, and which never should.
- Decide on a pilot limit, such as one hub, one courier, or one city.
- Record the second-attempt success rate before the pilot.
- Choose a comparison group of similar orders that don't get a call.
Data going in
- Check that the order feed has the right phone number, and has no sensitive fields it doesn't need.
- Remove orders that were already delivered, returned or cancelled just before dialling.
- Limit how many times one customer can be called for one shipment.
- Remove do-not-call numbers, and scrub against the national DND registry.
- Record where customers agreed to delivery calls.
Data coming out
- Match each field to a place in your courier or hub system.
- Confirm that a person can see landmark notes before the next attempt.
- Make repeat webhook deliveries harmless.
- Set an alert for results that don't arrive.
People
- Name who handles flagged requests on each shift.
- Brief hub staff on what these notes look like.
- Tell support staff that the calls are happening, and what the agent can't do.
- Name who can stop the campaign, and show them how.
Stop conditions
- Stop if the agent asks for or repeats an OTP or payment details.
- Stop if it says something was changed when it wasn't.
- Stop if calls go out outside the allowed hours or to a do-not-call number.
- Stop if results stop reaching the delivery team.
Deciding
- Compare second-attempt success against the group with no calls.
- Count complaints and do-not-call requests.
- Compare total cost per shipment, including staff time.
- Decide whether to expand, change or stop, and write down why.
24 cases to run yourself.
Have a colleague play each customer on a real phone line. Mark each case pass, fail or blocked in the spreadsheet, and note what the agent actually said.
A failed "must pass" case stops the pilot. Fix the cause, then run the whole list again, because a prompt fix for one case can break another.

The results log has one blank row. Add one row per shipment, using your own reference key in place of names or phone numbers.
The number that matters is second-attempt delivery, compared between similar shipments that did and didn't get a call. Also watch complaints and do-not-call requests, as these show the cost of calling.
