WhatsApp in India, and which numbers matter
WhatsApp is India's largest messaging platform by a wide margin, and every vendor page quotes WhatsApp users in India at you. Most of those numbers do not change any decision you are about to make.

The number that does matter
Not total users, but whether your customers use it. For almost every Indian consumer business the answer is yes, which makes the headline figure irrelevant to the decision.
The operationally useful comparison is response behaviour: messages on WhatsApp get read quickly and replied to conversationally, in a way email in India generally does not.
Reading vendor statistics carefully
Open rates quoted for WhatsApp are usually delivery-and-read rates on opted-in lists, which is a much easier bar than an email open rate on a cold list.
Treat any figure without a source and a date as marketing. Meta publishes its own numbers; those are the ones worth citing.
Be especially sceptical of conversion rate claims. They vary enormously by category and are almost never comparable across businesses.
What to measure instead
Your own numbers, from your own account: reply rate by segment, median response time, qualified conversations per campaign, and revenue attributed back.
Those four tell you more than any industry statistic, and they are the ones that change what you should do next.
Frequently asked questions
How many people use WhatsApp in India?
Hundreds of millions, and Meta publishes updated figures periodically. For business decisions, whether your own customers use it matters far more than the national total.
Is WhatsApp bigger than SMS for business in India?
For conversational messaging, yes in practice. SMS retains a role for OTP fallback and for reaching customers without WhatsApp.
