Start with the Puja calendar, not the call volume.
As of 7 October 2026, Sharad Navratri begins on 11 October. Kolkata's Durga Puja activity builds through the middle of October, so a campaign planned for this season has days, not weeks, to prepare its lists, scripts and follow-ups.
Kolkata's 2026 festival calendar places Durga Ashtami on 19 October and Bengal Vijayadashami on 21 October. Local Panchang calculations and individual Puja committee schedules can differ, so verify the final date and timing for the event you are promoting.
Retail shop
A clothing shop can call previous customers about a Puja collection, appointment or defined festive offer.
Builder's office
A property team can invite existing prospects to a Puja-period site visit or qualification call.
Indian grocery
An Indian grocery in New Jersey can call Bengali customers about a Puja bundle or pre-order window.
Build the campaign around specific conversations.
Split your database by reason to call.
Create separate lists for existing customers, new leads, event invitees, sponsors, past buyers and people who requested information. A previous Puja customer should not receive the same call as a new property enquiry.
Start with people who already know you. AI calling can do this.
Call previous customers first with a simple invitation or early-access offer. This gives you a warmer audience before you spend time on colder leads.
Add a location field to every lead. AI calling can do this.
For a Kolkata campaign, tag leads by locality or service area. A physical event should know whether a person is in Salt Lake, New Town, Ballygunge, Behala or outside Kolkata.
Decide one outcome for every list.
Your call should ask for one thing: RSVP, appointment, sponsorship discussion, registration or permission for a follow-up.
Use 11 October as a Navratri campaign trigger. AI calling can do this.
Navratri begins on 11 October 2026. If your offer covers Navratri and Puja, use the first call to announce it rather than waiting until the main Puja days.
Push event invitations before the crowded days. AI calling can do this.
For an event between 16 and 21 October, call prospective attendees several days beforehand. Closer to the main days, switch from introduction to reminder.
Run a reminder call 24 hours before the event. AI calling can do this.
Confirm the person's name, event, time and location. Give them a simple option to say they cannot attend.
Make the post-event call part of the campaign. AI calling can do this.
Call attendees afterwards to ask whether they want the product, appointment, quotation or follow-up promised during the event.
Offer a specific Puja benefit.
“Special festive offer” is weak. Say what the person gets: a consultation, event pass, product bundle, booking slot or defined discount.
Give the customer two simple choices. AI calling can do this.
Instead of “Would you like to know more?”, ask, “Would you prefer a visit on Saturday or Sunday?” Keep the decision small.
Build Bengali, Hinglish and English versions. AI calling can do this.
Kolkata audiences are not linguistically identical. Troika Tech supports 9+ Indian languages, so the conversation can be designed around the audience.
Create an objection path. AI calling can do this.
Prepare responses for “not interested”, “call later”, “send details”, “I am travelling” and “how much does it cost?”
Ask one qualifying question. AI calling can do this.
For a builder, ask the preferred property type. For a retailer, ask whether the customer is shopping for themselves or family.
Send qualified leads to a human. AI calling can do this.
Let the AI agent handle repetitive first conversations and pass interested prospects to your sales team without making the prospect repeat everything.
Schedule callbacks instead of relying on memory. AI calling can do this.
If someone says “call me tomorrow evening”, record that instruction and create the next action.
Stop calling people who say no. AI calling can do this.
Treat a clear refusal as an instruction to stop. Keep your promotional calling list clean.
Track connection rate by list. AI calling can do this.
Compare existing customers, recent leads and older databases separately. A poor result from an old database does not necessarily mean the script failed.
Track qualified leads, not just calls. AI calling can do this.
The useful number is how many people became genuine prospects, RSVPs or appointments. Call volume alone is an activity figure.
Record the reason for rejection. AI calling can do this.
Group responses such as price, timing, location, no requirement and wrong audience. Change the offer or list based on the pattern.
Review the first 100 conversations before scaling.
Check whether customers understand the opening, whether the offer is clear and whether the handoff works before increasing volume.
Keep the AI agent's job simple.
The agent does not need to run your entire sales process. Its strongest role is the repetitive first conversation: identify the person, explain one offer, ask one useful question, capture the answer and trigger the right next step.

- Answers to the five most common objections
- What qualifies a lead for human follow-up
- What to do when the customer says no
The 2026 Kolkata Puja campaign planner.
Use this as the operating sheet for the week. Adjust the calling days if your event has a different date, but keep the sequence: clean the list, test the script, launch, qualify, remind and follow up.
| Stage | When | Concrete action | Call objective | Next step |
|---|---|---|---|---|
| 1. Prepare | 7–8 Oct | Clean leads, remove duplicates, tag location and customer type. | No calls yet. | Finalise lists. |
| 2. Script | 8–9 Oct | Create Bengali, Hinglish and English versions and objection replies. | Prepare the conversation. | Approve script. |
| 3. Test | 9–10 Oct | Run a small batch with existing leads. | Check connection and response quality. | Fix the script. |

| 7. Main Puja | 18–20 Oct | Use reminders for confirmed attendees or opted-in follow-ups. | Reduce no-shows. | Record attendance. |
| 8. Dashami | 20–21 Oct | Keep promotional calling light and focus on agreed callbacks. | Complete pending conversations. | Move leads to post-Puja follow-up. |
| 9. Follow-up | 22–24 Oct | Call people who attended, enquired or requested details. | Convert interest. | Appointment, order or quotation. |
| 10. Review | 25 Oct | Compare lists, scripts and outcomes. | Find what worked. | Save the next campaign list. |
Date note: The 20–21 October placement around Dashami should be checked against your specific Puja committee or event schedule. Festival observance can vary by local Panchang conventions and community practice.
Use the festival as the idea, not just the label.
Tata Tea Gold
Tata Tea Gold's Puja campaign connected its festive activity with Bengali handloom traditions such as Kantha, Jamdani, Baluchari, Batik and Garad.
Lesson: Make your campaign culturally specific instead of adding a generic “Happy Durga Puja” line to an ordinary promotion.
Dabur Chyawanprash
Dabur's “Pujo with Dada” campaign used AI around the Puja experience and personalisation.
Lesson: Give AI a defined job in the customer experience rather than using it only as a campaign label.
Senco Gold & Diamonds
Senco's Puja campaign focused on the Bengali idea of homecoming and the festival's emotional connection.
Lesson: Identify the local reason people care about the festival and connect your offer to that reason.
Give the agent one short conversation.
Replace the brackets with your actual details. Keep the opening short and make the customer’s next choice obvious.
AI agent: Hello, is this [Name]? I’m calling from [Business]. I’ll take just 30 seconds. We’re inviting customers for our Durga Puja offer, [Offer], in Kolkata this Puja.
Customer: What is the offer?
AI agent: [Offer] is available from [Date] to [Date]. I can share the details and, if useful, help you book a slot. Would you like me to arrange that?
Customer: Yes, send me the details.
AI agent: Certainly. I’ll record that and have the details shared with you. Would you prefer a follow-up today evening or tomorrow?
Customer: No, I’m not interested.
AI agent: No problem, [Name]. Thank you for your time. I won’t take any more of your time. Have a good day and a happy Puja.
With Troika Tech, an AI calling agent can handle the first conversation, capture the response and route an interested lead to the human team for follow-up.
Check these six things before you call.
AI does not remove India's commercial-calling requirements. Treat consent, identification and opt-outs as part of campaign setup, not as an afterthought.
- Confirm that your promotional calling process follows the current TRAI commercial-communication and consent requirements.
- Use the appropriate registered telemarketing setup rather than ordinary personal mobile numbers for promotional calling.
- Maintain a suppression list for people who have asked not to receive further promotional calls.
- Make your business identity and purpose clear at the beginning of the call.
- Record consent, opt-outs and callback preferences in your CRM or calling system.
- Check the current TRAI rules immediately before launch because the regulatory framework can change.
| Before launch | Ready | Why it matters |
|---|---|---|
| Lead list is segmented | ✓ Yes | Different customers need different conversations. |
| Offer is specific | ✓ Yes | The caller has one clear reason to contact the customer. |
| Opt-out process exists | ✓ Yes | People who say no should not keep receiving promotional calls. |
| Human handoff is defined | ✓ Yes | Qualified leads need a clear next step. |
| Current TRAI requirements checked | ✓ Yes | Promotional calling must follow the applicable commercial-communication framework. |
Questions to settle before launch.
It is an automated voice conversation used to contact customers or leads about a Puja-related offer, event, invitation or follow-up. The agent can also capture responses, identify interested people and trigger the next action.
It can handle repetitive calls for invitations, registrations, reminders, enquiries and follow-ups. For example, a retailer can call previous customers about a Puja collection while the sales team focuses on people who actually want to visit the store.
Sharad Navratri begins on 11 October 2026. Kolkata Panchang sources place Durga Ashtami on 19 October, while Bengal Vijayadashami is listed on 21 October; local Puja schedules can differ because of tithi calculations and how the festival days are presented. Verify the final schedule for the specific event before calling customers.
Yes, AI calling can be designed for Indian-language conversations. Troika Tech supports 9+ Indian languages, but the exact language, voice and campaign configuration should be confirmed for your specific use case.
It can introduce the business, explain a defined offer, answer approved questions, qualify interest, schedule a callback and hand an interested lead to a human. It should not improvise claims, prices or availability that your business has not approved.
Yes. A campaign can separate people who want an immediate callback, a later call, more information or no further calls. That makes the second conversation based on what the customer actually said rather than starting from zero.
AI does not remove telemarketing obligations. Promotional voice calls are covered by India's commercial-communication framework, including rules around consent, registered headers and unsolicited commercial communication; check the latest TRAI requirements before launching a campaign.
Start with one list, one offer and one script.
If you are planning a Kolkata campaign for the 2026 Puja season, do not begin with a large call volume. Start with one clean customer list, one offer, one 30-second script and a small test batch. Troika Tech can manage the AI calling workflow, including the first conversations and qualified-lead handoff.
