What you get

WhatsApp marketing that feels like a conversation, not a spam blast

Most Kolkata businesses use WhatsApp for one-to-one chats. We turn it into a full-funnel growth channel with broadcasts, flows, catalogue, and analytics.

Key Takeaways

Broadcast campaigns done right

Segmented lists, business hour targeting, and clickable CTA buttons that drive replies and orders.

Automated order updates

Confirmation, dispatch, and delivery messages on WhatsApp so customers never call to ask 'where is my order?'

Catalogue selling inside chat

Show products, share catalogues, and let customers order directly from WhatsApp without leaving the app.

Why WhatsApp beats every other channel for Kolkata businesses

Your customers already live on WhatsApp. They use it to talk to family, order food, and chat with friends. When you message them there, you meet them in a space they trust and open several times a day.

Unlike email or SMS, WhatsApp gives you a two-way conversation. You can send an offer, answer questions, take an order, and confirm payment — all in one thread.

Why BrandStory

A WhatsApp marketing agency in Kolkata that owns outcomes

We are a full-service WhatsApp marketing agency. From strategy and setup to copy, automation, and ads, we manage everything so you can focus on running your business.

What working with us looks like

Strategy first

We map your customer journey and identify the highest-impact WhatsApp moments: welcome, order, reminder, reorder, winback.

Copy that converts

Bengali, Hindi, and English scripts for every message — friendly, short, and action-driven.

Automation built for you

Visual flows for welcome, order, payment, and support journeys — no coding required from your side.

Catalogue and payment setup

We set up your WhatsApp catalogue, payment links, and order forms so customers can buy inside the chat.

Team training and handoff

We train your staff to use the inbox, templates, and quick replies so your team stays fast and consistent.

Monthly reporting

Clear reports on opened, replied, ordered, and revenue influenced — every single month.

What we design for your WhatsApp growth

Every message, flow, and campaign is designed to start conversations and close sales — not just send updates.

Websites design visual
Broadcast Campaigns

Promotional blasts segmented by customer type, location, and past purchases.

Mobile applications design visual
Automated Chat Flows

Visual builders for welcome, abandoned cart, order status, and post-purchase follow-ups.

SaaS products design visual
WhatsApp Catalogues

Mobile-first product listings with prices, images, and direct order links.

Our philosophy: conversation is the new conversion

Your customers don't want more calls, more emails, or more forms. They want a quick, friendly chat — and WhatsApp is where they already are.

We build marketing that respects attention and drives action. Every message has a purpose: inform, assist, offer, or invite. No spam, no noise, no 'last seen' stalking.

For Kolkata brands — from Burrabazar traders to Park Street restaurants — WhatsApp is the most direct line to the customer. We help you own that line.

assets, helping engineering teams build products faster with fewer inconsistencies.

Quality assurance

How we ensure every WhatsApp campaign works flawlessly

Before any message goes to your customers, we run a battery of validation checks to protect your sender reputation and your brand image.

How We Validate Digital Experiences

Template Compliance Check

We verify every template follows WhatsApp's content, language, and category rules before submission.

Link & Button Testing

All CTA links, payment links, and media attachments are clicked and tested across Android and iPhone.

Opt-in List Check

We ensure contacts are sourced from compliant points and have given consent to receive broadcasts.

Spam Trigger Review

We sanitise copy to avoid spammy words, excessive caps, and over-promises that could block templates.

Flow Logic Simulation

Every automation path is simulated with test contacts, including edge cases like already-ordered or already-subscribed.

Delivery & Reply Monitoring

Post-send we monitor delivery failure rates, replies, and WhatsApp quality rating to catch issues early.

What our validation protects

Sender reputation

High-quality sends keep your WhatsApp number safe from limits and blocks.

Customer trust

Relevant, correctly timed messages build trust instead of annoyance.

Campaign ROI

Working buttons and links mean every click turns into a conversation.

Compliance safety

Proper opt-in records protect you from platform penalties or legal issues.

Brand image

Clean, professional messaging reflects well on your Kolkata business.

Data accuracy

Correct segmentation and tags ensure offers reach the right people.

Our quality principles

Every project we undertake is guided by a consistent set of principles that shape both the user experience and the business outcome.

Design with purpose, not decoration.

Validate decisions with research and feedback.

Prioritise clarity over complexity.

Build consistency across every interaction.

Design for accessibility and inclusivity.

Create systems that scale as products grow.

Balance customer needs with business objectives.

Continuously improve through testing and iteration.

From Insight to Experience

Successful digital products aren't defined by how they look—they're defined by how they perform for the people using them.

We treat your WhatsApp number as a precious asset. Every message we send on your behalf must be useful, timely, and safe — otherwise it doesn't go out.

About BrandStory

We help Kolkata brands grow with WhatsApp

BrandStory was born in Kolkata with a simple observation: customers don't read emails, they don't watch ads, but they always reply on WhatsApp.

We built a team of copywriters, automation designers, and media buyers who obsess over one channel — WhatsApp — and use it to drive real business results.

Who we are

A group of Kolkata-based WhatsApp strategists, copywriters, automation builders, and ad experts who love converting chats into orders.

How we work

We start with your business numbers, not vanity metrics. Every campaign is tied to a commercial goal and measured against it.

Where we add value

Between broadcast campaigns and automated flows, we close the biggest gap in Kolkata marketing: being present where customers actually respond.

Designed for Development

Beautiful designs should also be practical to build. Our whatsapp marketing playbooks, documentation, and engineering handoff process help engineering teams implement accurately and efficiently.

Focused on Long-Term Product Growth

Digital products evolve continuously. We create scalable design foundations that make it easier to introduce new features, improve user experiences, and support future business expansion.

The BrandStory Experience

Instead of a comparison table, imagine each point as an interactive feature card on the website.

Local language expertise

We write WhatsApp copy in English, Bengali, and Hinglish to match your audience.

Festive calendar mastery

Durga Puja, Diwali, Poila Boishakh, and more — we plan campaigns around them.

Fast implementation

We launch your first campaign within 2-3 weeks of kickoff.

Official API partner

No cheap bulk-SMS tricks. We use approved, safe WhatsApp Business API providers.

Full-service flexibility

Need just a broadcast? Or a full automation rebuild? We scale to fit.

Kolkata on the ground

We meet you in person if you want — we're local, not remote-only.

The Impact We Aim to Create

Instead of simply delivering design files, we help businesses achieve meaningful outcomes.

Orders

WhatsApp campaigns that turn viewers into buyers.

Appointments

Automated bookings and reminders that fill your calendar.

Leads

Instant replies that capture enquiries before they cool off.

Loyalty

Personalised offers that bring customers back again and again.

Trust

Compliant, respectful messaging that keeps your brand safe.

Every activity tied to one number: your bottom line.
