Rakesh's team spent 4 hours sending Diwali offers one by one.
Their competitor sent one broadcast and was already handling replies.
Rakesh manages a real estate team of 6. On Diwali morning, he asked his team to send the festive offer to all 3,000 leads in their database. His team spent 4 hours copying and pasting. Some leads got it twice. Some didn't get it at all. One person sent the wrong offer to 200 leads.
Meanwhile, their competitor had set up a single WhatsApp broadcast, scheduled it for 9am, and was already calling the people who replied. 3Sigma lets you be the competitor.
Sending One by One vs Sending a Campaign
Both methods get the message out. But one uses your team's entire day. The other takes under two minutes and then gets out of the way so your team can do actual selling.
Sending one by one (what most teams do today)
Time to reach 500 contacts
4 to 8 hours. Each rep opens WhatsApp, finds the contact, types or pastes the message, checks the name, sends. Repeat 500 times.
Personalisation
The rep types the name manually. Half the contacts get 'Hi [Name]' because someone forgot to replace the placeholder.
Tracking
None. You don't know who got it, who read it, or who replied β unless someone checks their own chat history.
Errors
Wrong message to wrong contact. Duplicate sends. Missed contacts. You only find out when someone complains or when the deadline passes.
What your team is doing meanwhile
Spending the entire morning on admin. Not calling new leads. Not handling enquiries. Not closing deals.
3Sigma campaign broadcast
Time to reach 500 contacts
Under 2 minutes. Select your contact list, pick your message template, schedule or send. Done.
Personalisation
Every message auto-fills the contact's name, their area of interest, and any other field from the lead profile. 'Hi Priya, here's our Diwali offer for the Whitefield project you asked about.'
Tracking
Delivery confirmed. You can see who replied and when. Responses flow into the CRM inbox and get assigned to reps automatically.
Errors
None. The template is set once and applied correctly to every contact. No paste errors, no wrong names, no missed contacts.
What your team is doing meanwhile
Handling the replies. The campaign runs on its own. Your team's time goes toward converting people who responded β not toward sending messages.
Six Campaign Types Indian Businesses Actually Run
Not abstract use cases β these are campaigns that teams on 3Sigma run regularly, with the kind of response rates you can expect.
Festival Offers
Used by: Real estate, retail, education, insurance
Example message:
""Hi Rahul, wishing you and your family a very Happy Diwali. We have a special offer on our 2BHK units in Whitefield this festive season β βΉ2 lakh discount and zero registration charges till November 15. Want to know more?""
When to send:
Diwali, Holi, Eid, Christmas, New Year, Onam, Navratri
What to expect:
Festival campaigns typically get 3β5x higher response rates than regular follow-up messages. People are in a buying mindset.
New Batch / New Project Launch
Used by: Education institutes, real estate developers, training companies
Example message:
""Hi Sneha, our new Data Analytics batch is starting on December 1st. You had enquired about this course in September β we have 8 seats left. The fee structure has also changed to make it more accessible. Can we schedule a call this week?""
When to send:
When a new batch starts, a new project launches, or new inventory becomes available
What to expect:
An education institute in Delhi sent this to 500 pending inquiries. 80 enrollments came in within one day. The counsellors spent the entire day on calls β a good problem to have.
Premium Renewal Reminders
Used by: Insurance agents, subscription businesses, annual service providers
Example message:
""Hi Mr. Verma, your LIC policy (No. 432156) premium of βΉ18,500 is due on December 31st. This year you also qualify for an additional top-up coverage. Should I send you the details? Happy to arrange a quick call at your convenience.""
When to send:
30 days before renewal, 15 days before, and 3 days before
What to expect:
Insurance agents using 3Sigma for renewal campaigns report renewal rates going up 25β40% compared to calling each client individually β because messages get seen even when calls don't connect.
Re-engagement Campaign
Used by: Any business with leads that went quiet after initial interest
Example message:
""Hi Kiran, it's been 3 months since you enquired about our solar installation. We've installed 40 more systems in your area since then β including 6 in your apartment complex. Our new financing option also means zero upfront cost. Would you like an updated quote?""
When to send:
Leads that went silent 30, 60, or 90 days ago
What to expect:
Re-engagement campaigns bring back 8β15% of old leads that were otherwise written off as lost. For a database of 1,000 old leads, that's 80β150 conversations you wouldn't have had.
Post-Purchase Follow-up
Used by: Real estate, services, consumer products
Example message:
""Hi Anita, congratulations on your new home! It's been 3 months since possession. We wanted to check in β how is everything going? We also have a referral program where you can earn βΉ10,000 for every friend or family member who books with us. Know anyone who's looking?""
When to send:
30 days after purchase, 90 days after, and at anniversary
What to expect:
Referral campaigns sent post-purchase consistently outperform cold campaigns. The customer already trusts you β this is the lowest-cost way to get new leads.
Holi / Seasonal Collection Launch
Used by: Retail brands, fashion, home decor, gift businesses
Example message:
""Hi Pooja, our Holi collection is live β we've sent your exclusive early access link. This includes 30 new designs added just for this season. Free shipping on orders above βΉ999 till March 20th.""
When to send:
Before major festivals and seasons β typically 2 weeks before the occasion
What to expect:
Past-customer campaigns for seasonal launches get 4β7x higher conversion compared to running ads to cold audiences. Your existing customers already know your quality.
Personalisation Beyond "Hi [Name]"
Most people think personalisation means inserting a first name. 3Sigma lets you personalise based on anything in the lead's profile β making each message feel like it was written specifically for that person.
A generic message
"Hi, we have an exciting offer on our properties. Please contact us for more details."
Open rate: low. Replies: almost none. Gets ignored alongside every other generic message.
A personalised 3Sigma message
"Hi Rahul, it's been 45 days since you enquired about the 2BHK in Whitefield. We've just launched a new payment plan β 10% down, rest over 5 years at 8.5% interest β that might work better for your budget. We also have 3 units available on your preferred floor (2nd and 3rd). Can we connect this week for a 15-minute call?"
Uses: name, days since enquiry, project name, product interest, floor preference, budget signal. Every field pulled automatically from the CRM.
Fields you can personalise with
{name}Rahul, Priya, Mr. Sharma...
Contact's name from CRM
{days_since_enquiry}45 days, 2 weeks, 3 months...
Automatically calculated
{product_interest}2BHK, Term Plan, Data Analytics...
From the lead's enquiry details
{location}Whitefield, Powai, Bandra...
Area or city the lead mentioned
{last_interaction}your site visit, our call last week...
Last logged activity from CRM
{custom_field}Any field you've added to your CRM
Budget range, unit type, batch preference, etc.
WhatsApp Business API: What You Need to Know
To send bulk WhatsApp messages, you need access to the WhatsApp Business API β not the regular WhatsApp Business app. The API is what allows campaigns at scale without risking your number being blocked.
There are two types of messages in the WhatsApp ecosystem, and understanding this helps you plan your campaigns:
Template Messages (for first-touch campaigns)
When you message someone who hasn't texted you first in 24 hours, you must use a pre-approved template. These are submitted to WhatsApp for approval (typically takes 1β3 business days). Your Diwali offer, batch announcement, and renewal reminder all use templates.
Free-form Messages (within 24-hour window)
Once a lead replies to your message, a 24-hour conversation window opens. Within that window, your reps can send any message β no template required. This is where the real selling happens.
How 3Sigma handles this for you
API setup included
3Sigma connects your number to the WhatsApp Business API as part of the onboarding. No separate technical setup needed.
Template library pre-built
Common templates for festivals, reminders, launches, and re-engagement are already in the system. You customise and submit for approval.
Compliance built in
3Sigma only sends to contacts who have a legitimate relationship with your business. This is the correct practice and it's enforced in the platform.
Responses come back to CRM
When someone replies to your campaign, their response appears in the 3Sigma inbox β not your personal WhatsApp β and gets assigned to a rep.
When to Send Campaigns for Best Results
Timing your campaign well makes a real difference. These patterns are based on response data from campaigns sent by Indian businesses using 3Sigma.
Best times to send
TuesdayβThursday, 10amβ12pm
People are at work, have checked morning emails, and are making decisions. Response rates are typically 40β60% higher than Monday morning or Friday afternoon.
TuesdayβThursday, 5pmβ7pm
Work day is winding down. People have time to check messages and respond before dinner. Strong for B2C campaigns β real estate, education, insurance.
Saturday, 10amβ12pm
Works well for consumer-facing campaigns. People are more relaxed and have time to read. Good for retail, education, and B2C real estate.
Sunday or Monday morning
Lower response rates. Sunday feels intrusive for business messages. Monday morning is chaotic for most people β your message gets seen but not acted on.
How scheduling works in 3Sigma
You don't have to be awake at 10am on Tuesday to send your campaign. Set it once and it goes out at the time you specify β even if you're in a meeting, traveling, or asleep.
Create campaign in advance
Set up the campaign today for next Tuesday. All the personalisation fields are pre-filled. You review it once and schedule.
Set the exact time
Pick the date and time you want it to go out. 3Sigma queues it and sends at that exact time, managing delivery across all contacts.
Campaign report available immediately after
Once the campaign is sent, you can see delivery status and who's responded. No waiting until end of day.
Recurring campaigns possible
Annual renewal reminders, quarterly check-ins, monthly offers β set the schedule once and it repeats automatically.
What Happens When People Reply
A campaign is not a one-way megaphone. People reply. The quality of what happens after the reply determines whether your campaign generates revenue or just generates messages.
Replies flow into the CRM inbox
Every response to your campaign lands in the 3Sigma team inbox β not a personal WhatsApp that only one rep can see. The manager can see all replies at once.
Replies are assigned to reps
Based on your assignment rules, each reply is assigned to a specific rep. That rep gets a notification and can continue the conversation from their phone.
Replies are linked to the lead's profile
When someone replies, 3Sigma connects that response to their existing lead profile. The rep can see the full history β when they first enquired, what they looked at, every previous interaction.
High-intent replies flagged
Responses like 'yes interested' or 'can you call me?' are flagged as high-priority. The rep sees these at the top of their inbox.
Example: Diwali campaign results view
Replies (most recent first)
Yes interested, can you share details?
What floor are the remaining units on?
Can someone call me today?
What is the total cost with registration?
+ 243 more replies. All assigned to reps.
What's Included in 3Sigma WhatsApp Campaigns
Every campaign feature is built into 3Sigma. No separate tool. No extra setup per campaign.
Bulk Broadcast
Send to hundreds or thousands of contacts at once using the WhatsApp Business API. Contacts are reached reliably β no risk of your number being flagged for spam.
Message Personalisation
Auto-fill name, location, product interest, days since enquiry, and any custom field from the lead profile. Every message feels written for that specific person.
Contact Segmentation
Send to specific groups: leads from a particular source, leads at a specific pipeline stage, leads in a city, or any custom filter. Don't blast everyone β target the right people.
Campaign Scheduling
Set campaigns to go out at the optimal time. Schedule days or weeks in advance. Recurring campaigns for renewals and seasonal events run automatically.
Delivery and Response Tracking
See delivery confirmation and who replied after each campaign. Know which contacts engaged so your reps can prioritise follow-up calls.
Centralised Response Management
All replies come back into the 3Sigma team inbox and get assigned to reps automatically. No reply gets lost in a personal WhatsApp. Every response gets a follow-up.

What Businesses Say About Running WhatsApp Campaigns
"We have 3,000 leads in the database from the last 2 years. Before 3Sigma, they just sat there β we couldn't reach all of them regularly. Now we send a campaign before every major festival. Our Diwali campaign got 312 replies in 6 hours. The team spent the whole day handling enquiries. That one campaign resulted in 18 bookings in the following week."
Arun Kapoor
Sales Head, Real Estate Developer, Pune
"We run a coaching institute and our biggest challenge is converting pending inquiries when a new batch starts. We used to call everyone individually β 2 counsellors would spend 3 days making calls. Now we send a campaign on Day 1. 400 messages go out in the morning. By afternoon, 60 to 80 people have replied asking about the batch. The counsellors spend the next 3 days on meaningful conversations, not cold outreach."
Nandita Rao
Admissions Head, Coaching Institute, Hyderabad
"I have 600 insurance clients and renewal season in November is always chaotic. Before 3Sigma, I'd miss renewals because I couldn't track who I'd called and who I hadn't. Now I send a renewal reminder campaign 30 days before due date, another 15 days before, and one on the due date. My renewal rate went from 58% to 81% in one year. The difference is that the reminders actually reach people β most of my calls weren't being picked up."
