B2C app startups · WhatsApp marketing

Use the app that is already open on every phone to bring users back to yours.

WhatsApp marketing for a B2C app is the use of WhatsApp Business for permissioned messages, support and referrals that send users back into the app. GullySales plans the opt-in, the templates and the conversation flow, and works within the platform's current rules.

What WhatsApp marketing means

WhatsApp marketing is sending updates, offers and reminders to customers on the app most Indian buyers already check daily. GullySales sets up business WhatsApp, writes the message templates and keeps the list consented and current.

For B2C app startups

Where it usually goes wrong, and what we would do.

  • “WhatsApp is where the user already pays attention”

    A user who ignores a push notification may answer a message in a chat. That attention is borrowed from friends and family, so a message that reads like a broadcast gets blocked and costs the number's standing.

  • “Opt-in decides everything”

    Messages are sent to people who agreed, for the purpose they agreed to. The opt-in line at sign-up, the wording and the record kept are as important as the message. Check the platform's current rules before sending.

  • “A chat can finish what the app could not”

    A user stuck at KYC or unsure about a payment may complete it in a short conversation. The reply needs to be prompt enough to feel human and to have a person behind it, with a handover from automation.

  • “A forward is a free referral”

    Users share offers and invites in family and friend groups. A share message written to be forwarded, with a link that opens the right store page, carries more trust than an ad, as long as it reads like a person wrote it.

What we do

What we deliver for B2C app startups.

Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.

  1. Opt-in design

    The wording and placement of the WhatsApp permission at sign-up and in the app, and the record stored in your CRM.

    Result: A recorded permission for each number.

  2. Template set

    Approved templates for welcome, first action, abandoned step, payment reminders and winback, in the user's language.

    Result: A template library ready for approval.

  3. Conversation flows

    Menus and replies for common questions, with a clear point at which a person takes over.

    Result: Common questions answered, with a person behind them.

  4. Click-to-chat entry points

    Buttons in ads, on landing pages and inside the app that open a chat with a first message already written.

    Result: Entry points that start a conversation.

  5. Share and referral message

    Wording for users to forward, with a tracked link that opens the right store.

    Result: A referral message you can test.

  6. Quality and block watch

    A routine for reviewing blocks, reports and replies so messaging stays within the platform's limits.

    Result: Early warning when messages annoy users.

How the result is measured

  • Messages delivered
  • Reply rate
  • Enquiries from WhatsApp

Recorded as a baseline before work starts, so every later report has an honest comparison.

What to send

The WhatsApp messages an app sends, and the moment each one belongs to.

Welcome after opt-in
One message in the user's language with the first task and a help option. It confirms the permission and sets the tone before any offer.
KYC or setup reminder
A message naming the step a user left unfinished, with a link back to that screen. It can finish a job the app screen could not.
Payment status update
A message sent on a failed or pending payment, with the next step. It is a service message, so it should not carry an offer.
Order or session confirmation
A confirmation of what the user booked or ordered, with a way to reply. It gives the user a thread to come back to.
Winback to a lapsed user
A note naming what they did last and what is new, sent only if they agreed. A broadcast to everyone gets reported.
Forwardable invite
A short message the user shares in a family or friend group, with a link to the right store. It must read like a person wrote it.

Who it is for

This is written for these B2C app startups.

  • Consumer finance and payments apps
  • Health, fitness and habit apps
  • Food, grocery and quick-delivery apps
  • Learning and exam-prep apps for students
  • Local services apps for plumbers, tutors, beauty or repairs
  • Gaming and entertainment apps
  • Social and community apps built around a language or a hobby
  • Utility apps for transport, bills or government services
  • Subscription apps with a free tier and a paid upgrade

Not for

It is not the right fit if.

  • You have not recorded which users agreed to WhatsApp messages, and sending to the whole list would risk a block.
  • No one will answer when a user replies, so a two-way channel would leave replies hanging.
  • Your templates are not yet approved on the Business platform, and sending from a personal number is not a route to follow.

How it works

How the whatsapp marketing work runs

The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.

  1. 1

    Read the chats you already have

    We read how customers write to you, which questions repeat and where a chat goes quiet. The repeated questions decide what gets automated first.

  2. 2

    Sort the list and the permission

    Contacts who asked to hear from you are separated from numbers that only sit in a phone book. We agree the wording new contacts will see before they say yes.

  3. 3

    Choose the app or the API

    One phone and a small team can stay on the ordinary app. Several people on one number, templates or a CRM link need the API through a provider, which is its own piece of setup work.

  4. 4

    Write the replies and the plan

    The greeting, away message, saved replies and handover rule are written in your words and approved by you. The message plan and its templates follow.

  5. 5

    Connect the record and test

    Each link carries its source line and each chat lands in the CRM. We test on real phones, including a customer who asks for a person.

  6. 6

    Read the unanswered questions

    A question the first reply could not answer becomes a new saved reply or a fixed handover. Stop requests are watched too, with the number's quality rating where the API is used, since both show a message plan that has gone too far.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.

  1. Step 1

    Sales audit

    Find where deals are being lost and what to fix first.

    Start here if you cannot say where orders are lost.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
Can we message every user?
No. Only those who agreed, and only for what they agreed to. Keep a record of the permission and offer a clear way to stop.
Do we need the WhatsApp Business API?
For automated messages at volume, yes, through an approved provider. The Business app suits very small teams. We compare the options against your volumes.
Will it replace push notifications?
No. Each channel does a different job. Push is free for in-app prompts, while WhatsApp suits reminders and help that need a reply.
What happens if many users report our messages?
The sender's quality rating drops and the platform can limit or pause the number. Reports come from messages sent without consent or at the wrong moment, so send only to opted-in users and watch blocks and replies. Check the platform's current rules.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
How soon will we see results?
It depends on the trade, the channel and what is already in place. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
What do you need from us?
Your brief, and a conversation. After that, access to whatever this work touches, such as your website, your accounts or your enquiry record, and time with the people who handle your enquiries.
What if we are not happy with the work?
Tell us and the plan changes. Everything is reported against the baseline, so a number that is not moving is visible to both sides. The term is in your written scope, and the refund and cancellation policy sets out the rest.
