WhatsApp is the channel Indian customers actually read. That is exactly why mistakes on it are expensive: a banned number, a blocked brand or a hot lead left waiting for two days. Here are the seven problems we see most often when businesses come to us, and what fixes each one.
1. "Our number got banned"
Why it happens: bulk messages sent from the normal WhatsApp app or the WhatsApp Business app, often through browser extensions or "bulk sender" software. WhatsApp detects the pattern, and people who did not expect the message block or report it.
The fix: move business messaging to the official WhatsApp Business API, which is built for sending at volume with approved templates. Keep your personal number personal. If a number has already been banned, start the API on a fresh number rather than fighting for the old one.
2. Templates keep getting rejected
Why it happens: the template is in the wrong category, has a variable like {{1}} at the very start or end, has spelling mistakes, or promises something the commerce policy does not allow.
The fix: pick the category honestly (an offer is marketing, an order update is utility), write a full sentence around each variable, and keep the first line clear about who is writing and why. Build a small library of approved templates for your common situations so you are not waiting on approval before every campaign.
3. People read the message but nobody replies
Why it happens: the message reads like an advertisement, asks for nothing, or asks for too much.
The fix: give people one easy next step. Quick-reply buttons ("Yes, send details", "Call me", "Not now") get far more responses than "Contact us for more information". Personalise with the customer's name and something relevant, like the product they bought or the city they are in.
4. Messaging people who never asked to hear from you
Why it happens: a bought database, an old Excel sheet from an exhibition, or every number from the accounts software gets added to the broadcast list.
The fix: collect opt-ins on purpose. Add a WhatsApp checkbox to your website forms, a click-to-chat button on your site and Instagram, and a QR code at the billing counter. A list of 500 people who said yes beats 10,000 strangers, and it protects your number's quality rating.
5. Leads reply, and then nobody follows up
Why it happens: replies land on one person's phone, that person is busy or on leave, and the enquiry goes cold. This is the most common problem we see, and the most expensive.
The fix: use a shared team inbox where every chat is assigned to someone, with reminders for follow-ups. Add an instant automated first reply so the customer knows they have been heard, even at 11 at night. Then connect WhatsApp to your CRM so every enquiry becomes a lead with an owner.
6. Sending the same broadcast to everyone
Why it happens: segmenting feels like extra work, so the whole list gets every message.
The fix: start with three simple groups: recent customers, past customers who have not bought in a while, and enquiries who never bought. Each group needs a different message. You will spend less on message charges and see more replies. Our guide to WhatsApp API pricing shows how much segmenting saves.
7. Not measuring anything
Why it happens: the campaign goes out, a few people reply, and nobody checks what actually happened.
The fix: after every campaign, note four numbers: delivered, read, clicked and replied. Then note how many replies became sales. After three or four campaigns you will know your normal results, which message styles work, and which segment is worth the most.
A quick self-check
If two or more of these problems sound familiar, start with the basics: the official API, a clean opted-in list, and a shared inbox with follow-up reminders. Our free WhatsApp Marketing Checklist walks through all of it in two pages.
Frequently asked questions
Why was my WhatsApp number banned?
Usually because messages were sent in bulk from a normal WhatsApp or WhatsApp Business app number, or because many recipients blocked or reported the messages. Moving business messaging to the official API, and messaging only people who opted in, prevents most bans.
Why does WhatsApp reject my message template?
The common reasons are a wrong category (a promotion submitted as utility), variables with no surrounding text, spelling mistakes, or content that breaks WhatsApp's commerce policy. Fix the category and wording, then resubmit.
What is a good reply rate for WhatsApp campaigns?
It depends on your list and offer. Track your own baseline over three or four campaigns and try to improve it. Lists of recent customers almost always reply far more than cold or old lists.
